View Full Version : Quality of ATSB reports getting worse?

I read ATSB reports habitually. As a low time pilot that struggles to fly as often as I'd like I find it helps to keep my head in the game.

However, I have to wonder if lately they've been getting work experience kids to write them? This gem being an example:

Old Akro, your post makes me wonder something that no-one I know has been able to answer.

At my home airfield there have been two serious accidents in the past couple of years. Both were non-fatal but the aircraft (both VH registered) were destroyed. The authorities were informed and I believe attended to interview people, but reports were never published.

So, what criteria has to be addressed for an investigation to happen and a report to follow?

Why is someone landing nosewheel first in a 182 at Bathurst considered worthy of a report but two near-fatal accidents not?

Short answer? Resources. So they pick and choose based on criteria available on the ATSB website. This extract was before BASI was amalgamated within the ATSB.

‘In recent years, the Bureau has adopted a policy of selective investigation, similar to many of our equivalent organisations in other countries. The traditional approach in Australia had been to investigate everything, no matter how minor. However, many categories of air safety occurrence are repetitive in nature, such as ground loops involving aircraft with tailwheel undercarriages, and no new prevention knowledge is gained by continuing to investigate such events. However, the law requires that all accidents and incidents must be reported. Because BASI receives all these reports, it retains the ability to monitor trends, and can initiate an investigation into safety issues raised – for example, by a number of relatively minor occurrences. While these events individually would not warrant full investigation, considered as a group they may be indicative of broader systemic safety deficiencies – a topic which will be addressed later in this paper.
In practice the Bureau does not distinguish operationally between accidents and incidents – they are all ‘safety occurrences’. The objective of selective investigation is to concentrate the Bureau’s resources on in-depth investigations, which offer the greatest potential to enhance air safety. BASI has developed and refined various criteria to decide which events will be looked at most closely – one of these is a primary emphasis on the safety of fare-paying passengers in any category of operation – high capacity regular public transport (RPT), low capacity RPT and charter, and other commercial operations involving fare paying passengers.
AVIA5022 The Purpose of Investigation – Edition 4. 11

In addition, in part enabled by the redeployment of resources as a result of the selective investigation policy, BASI is placing a much stronger emphasis on applied systems safety studies. This is aimed at identifying and rectifying underlying factors within the aviation system which can impact upon safety at the ‘sharp end’ – that is, in the cockpit, cabin, control tower, maintenance workshop, or on the ramp.’

The issue I have with the report is the lack of investigation into the Right Hand fuel tank indication of being half full but the actual fuel found to be only 25 L. (total).

Read this:

https://www.avweb.com/news/maint/182907-1.html

HZE was produced in 1985 so some of that information is irrelevant but the filling of the tanks - very!

A little bit of research added to the ATSB report would have provided valuable knowledge to the readers.

And that would help keep your head in the game.........

Short term profit and greed is why we cant have anything nice in Australia anymore. The profit & cost margin.

How do we as a society accept this? How can we accept undermanned authorities when we bring in taxi drivers on working visas.

Its messed up.

It takes a well lead, hard working, forward thinking committed society to make sacrifices to have good infrastructure, beautiful and liveable cities and well run authorities that are not tied at the wrists.

Anything worthwhile, long lasting and first-world takes sacrifice and commitment and and we in Australia no longer have the willingness nor guts to do it. We are selling out to the lowest bidder, for the least cost and greatest profit. In my lifetime we have started to become third world.

Our authorities are run at bare bones, our once beautiful city buildings, parks and skylines are being mined by property developers, our infrastucture is selling to private hands.

There is nothing nice for the long term for the general citizens of our country in this.

The classic example; Airport Security and Border Control - security and CBP queues doubled out the entrance doors but fewer than half the lanes active because of understaffing.

Public transport: Sydney about $3 to get from Sydney to the last stop on the train line beforre Sydney airport. Another $12 on the fare if you take the next stop to the airport - MacQuarie Bank owns Sydney Airport.

Melbourne: no public transport link at all!

I want a government that can govern, cities that belong to the people.

Next thing you'll be telling us that public infrastructure should be returned to public ownership!

Back when airports and ground transport infrastructure were owned and run by public institutions, how many millionaires were making their millions out of that infrastructure? None! See how inefficient that is?

Now there are plenty of millionaires making their millions milking these assets. That's efficient!

While you're all busy criticising the delivery, how about thinking of the message and the audience?

If a major job of such a report is to inform, then it's told a fair story - particularly to newer recruits to GA. Unsubtly we can see from this:

(1) What can happen when the juice runs out
(2) That Cessna's and other craft with similar fuel systems can effectively cross feed between tanks when not level
(3) That the end result of (2) can mean you end up with far less fuel than you originally thought
(4) That some tank and filler siting mean that you may never fill a tank properly if the craft is not level
(5) Before taxiing out on a longer jaunt check you should check your fuel levels with a dipstick (on a level surface!)


Personally I've often wondered when reading of similar issues why more people don't do (5)?

As to the quality of the report, well we can all do better, and if I wasn't being the devil's advocate I might have a negative comment or two, but in the end it's the same old story that's only been told hundreds of time before in hundreds of such reports so perhaps they've just run out ways of saying the same thing :ugh:

Certainly not being an apologist here but, as is the way these days, the report is effectively anonymised as it issued by an organisation. However it will have most likely been written by an individual and (hopefully) reviewed by another...

Individuals are not born with the ability to write concise, accurate, and informative reports - these things take time and experience. Additionally in a world such as we have today where everyone's sensibilities need to be taken into account, writing public reports is not made any easier than it was, to my mind the converse is true.

Perhaps then this could have been a 'first report' by someone? Certainly if I were allocating lead investigatory and reporting roles to someone who had not had such a role before then this would be the type of accident I'd choose - non-fatal, and to a certain extent not that uncommon.

Regardless I think it still told sufficient a story to get the points out of it I earlier elucidated. Yes you could shorten it and make it more succinct, but then I'm sure you'd all complain there wasn't enough background or something :rolleyes:

You really don't get it, do you!

Fuel gauge indicating 50% in Right Hand tank = 25% fuel available and the noise stops..... and you don't want to know why.

The planned fuel consumption, the electronic gadgetry and the fuel indication were probably in close alignment with the expected endurance remaining - which is how we operate aeroplanes.

Over different terrain, this could have been a fatal accident.


full rich all the time, that's a dangerous practice - What?!

26th Aug 2017, 04:48
I think people should take another look at First Principals post because it is the most sensible I have read. The 75ltr/min figure was what the pilot planned on, there is no mention of what the inflight figure was. From my point of view the report is all about being aware of how much fuel you actually have before departure and being aware at all times how much is left. Who in their right mind relies on the fuel gauges of light aircraft anyway?

The planned fuel consumption, the electronic gadgetry and the fuel indication were probably in close alignment with the expected endurance remaining

All of that points to the fact that the assumptions made were obviously incorrect. Unless there was a fuel leak somewhere, if the pilot overestimated how much fuel was on board then all the other assumptions are incorrect. The electronic wizardy is only as ggod as the information put into it. It applies to airliners as much as light aircraft.

This attitude is part of the problem - pilots hear this dribble often enough and they don't look at the gauges.

If the gauges are not reliable, the aircraft is unairworthy. Write them up and get them fixed, whether or not the aircraft is 'light'.

While I applaud the sentiment it's not necessarily correct. The MEL for many aircraft may not include operating gauges, particularly if alternative methods of calculating the fuel quantities are available.

One of the more well known is Air Canada 143, aka the Gimli Glider. As I recall this new 767 had a fault with all of the fuel gauges but was still able to operate if the fuel quantities were calculated as sufficient for the proposed flight. While in this instance the ensuing miscalculations resulted in a major incident the point first of all is that 'light' or not, gauges are not necessarily required, nor are they infallible.

This is why I return to my earlier comment - dipping the tanks prior to a flight, particularly of any duration, is a no-brainer. It costs a couple of minutes of time perhaps, but could save an awful lot of grief. And if there's any lingering question, do it en route if/when you land - something else that could be taken from this report if you'd care to, the data is there...

I could not agree more. Light aircraft fuel contents gauges are often unreliable for many reasons. Yet, when leaving the factory floor, they don't start off that way. Same with parking brakes. The problem then arises where general aviation instructors and pilots accept these type of defects as normal GA and then quietly sneak off and leave the decision to write up the snag to the next unsuspecting pilot who flies that aircraft. Yeah,:ok: right:ugh:

Aircraft owners have the moral responsibility to do their bit and supply fuel tank dip sticks. After all, it is in their financial interest to keep the fuel gauges serviceable and thus lessen the chance of someone running out of fuel due to a defective fuel gauge. Having said that, if dip sticks are part of the aircraft equipment it would be good airmanship (Non technical Skills, if you prefer that buzz-word) for pilots to use them.

full rich all the time, that's a dangerous practice - What?!That's what I said. Book endurance figures only work if the engine is leaned for cruise in accordance with whatever assumptions were made by the book writers about cruise engine settings.

Ironically in this case, the actual hourly fuel consumption was probably higher than the (very rich-for-cruise) 75 litres per hour assumed for planning. By my count, there were 5 take offs and a number of very short legs. During all of those take-offs and climbs I'm assuming it was 'balls to the wall', in which case the engine was gobbling in the order of 100 litres per hour (unless the pilot was using the target EGT leaning during climb technique, but even then the fuel consumption would have been much higher than 75 litres per hour during take off and climb.

For example, I'm pretty confident that during the 30 minute flight from Katalpa to Pine View Station the aircraft consumed more (a lot more) than 37.5 litres.

Fuel consumption for a 4.5 hour trip with one take off and landing is vastly different than a 4.5 hour trip with 5 take-offs and landings (including manoeuvring in the circuit and taxiing at each).

If the gauges are not reliable, the aircraft is unairworthy. Write them up and get them fixed, whether or not the aircraft is 'light'.

CASA in its wisdom reintroduced regular fuel tank calibration. Gigantic waste of money and a retrograde step in my view. There is no reason why the fuel gauges should no be reasonably accurate.

Furthermore, the thinking owner / pilot will be doing periodic cross checks of refuel quantities with gauge readings.

I have tabled every fuel tank calibration that out Seneca has had in its life and there is very little variation. In fact I would suggest that the major variotiin is caused by LAME's who don't know how to do it properly.

Then of course there is the $2 piece of wood Dowling that every aircraft should have as a calibrated dipstick. Once again, it probably only takes 6-10 refuels to draw a calibration line.

Gee - maybe it would be a safety enhancement if the ATSB published some tips about this??

Were they always this bad?No, they were not. It appears that, these days, the writer is just not of the quality he was in the old days.

A few examples from that report linked to by MagnumPI:

Passing 12 NM (22 km) on approach to Mildura, the pilot made a broadcast to advise that they
were approaching the airport. The pilot reported that during the approach, the AWIS indicated that
the cloud base was varying between 1,000 ft and 3,000 ft. Therefore, the pilot decided to
approach Mildura overhead to observe the conditions. Clunky and overly wordy. The words, "the pilot" appear far too often. The first sentence is entirely irrelevant. This entire passage could thus have been written more simply and concisely:

Approaching Mildura, and with the AWIS now indicated a cloud base varying between 1,000 ft and 3,000 ft, the decision was made to observe the conditions from overhead the aerodrome.

Note that this simpler form has avoided the dreadful "the pilot" altogether.

Yes, the ATSB are politically correct too, and will go to whatever lengths it takes to avoid divulging genders, but this attitude has been taken to ridiculous lengths in this report. The phrase "the pilot" appears 31 times in this short report. The gender-neutral "they" also appears an excessive number of times, and on many of these occasions, the usage is wrong. Wrong because "they" means "more than one".

Examples:
The pilot reported that the aircraft was parked with the left wing low at the fuel point and when they
refuelled the fuel tanks in the wings, so they might have stopped before the tanks were full.It is most likely that this refuelling was done by a single person, which means that "they" cannot be used.

On approach,
they noticed there were powerlines on both sides of the road and changed their landing site to a
nearby paddock.We know that at this stage of proceedings, the pilot was the only occupant, so again, "they" cannot be used. In their zeal to be politically correct, they are subverting the language!

A poorly written report. Makes one long for the Macarthur Job days. Now don't get me started on the quality of their investigations.

And did you rely on the other fuel gauges to determine how much fuel you considered was remaining in the tanks?

The ATSB reports are not written for pilots but for the "man on the Clapham omnibus" Literacy skills are not that good in society genarally so the report serves its purpose. Even newspapers are written for the reading ability of a 12 year old. If the message of the report was to inform Joe average that pilots should be certain of how much fuel is in the fuel tanks instead of assuming how much there is, then job done from what I can tell. All the other discussion on the number of times the word pilot appears is just intellectual pontificating!

And did you rely on the other fuel gauges to determine how much fuel you considered was remaining in the tanks?Didn't have to. I was in the circuit and about to land. The gauge for one tank suddenly dropped from the reading that coincided with the calculated consumption to a reading of zero, because of (what turned out to be) a wiring problem. I knew that the tank had not suddenly lost a quarter of its contents and I wasn't running on that tank anyway. If everything dropped to zero and it turned out those indications were accurate, my only option would have been to ..... do what I was already doing.

As to whether the report serves its purpose, unnecessary waffle distracts and therefore detracts from the effectiveness of safety messages.

It appears that, since the days of the Macarthur Job and the Aviation Safety Digest there has already been considerable dumbing down in the area of ATSB reports and investigations.

The problem with dumbing down is that there is no end to it. You either accept a standard, and work to maintain that standard, or allow the open-ended dumbing down, resulting in wordy reports that fail to convey the message effectively.

If you are getting bogged down in where the full stop should be or how many times the word pilot appears then you might as well stop reading any report the ATSB publishes.

Myself, and many others are growing concerned about the quality of the written reports.

Macarthur Job would be turning in his grave. Not just at the writing, but the investigations, too. Some recent reports look like they have been written by school children, doing work experience at the ATSB. Are the investigations going the same way?

I would agree with you Lead. Always struck me as strange that if the pilot had broken so many rules, as alleged by so many people, why was he not charged with the offences and brought before the courts? He most certainly not the first person to be caught out by the vagrancies of Norfolk Island weather, and most probably won't be the last.

The salient point of these reports might be obvious enough but I do believe that if there are consistent grammatical errors that this indicates a lack of thoroughness in the overall investigation. Just because these safety incidents are often repetitive in nature doesn't mean that a poorly written report is adequate.

If you submitted a report like this to an academic institution it wouldn't cut the mustard. We are expected to believe that scientific investigation has taken place, so why shouldn't there be a factually accurate and grammatically correct report?

The A330 report linked above in the other thread is most interesting as it clearly violates the impartiality standards which the ATSB are supposed to uphold. Irrespective of whether or not you think the flight crew did a good job in the circumstances (which I actually do as well), it is not the ATSB's role to use subjective statements which make it more like a narrative than a report.

I just had a look at the ATSB site to see what was released in the common end of the month dump.

There are currently 97 reports pending.

Over the last 6 months there has been an average of 8 new incidents per month.

Over the last 6 months the number of released reports has averaged slightly under this (something like 7.3).

Not a picture of a department on top of things.

Which puts the pedantry of this report in the spotlight. Why waste time producing such trite when there is such a backlog of real work.

I was interested to read this newly minted tome from the ATSB regarding the Chieftan that bounced a main gear on a truck on approach to Barwon Heads.

https://www.atsb.gov.au/media/5773497/ao-2017-040_final.pdf

I struggle to find it cohesive, let alone reaching any sort of conclusion of any value.

Not to mention the factual error that the maximum vehicle height in Victoria is 4.3m not 4.6m. Which makes a lot of the reports discussion about landing approach angles valueless. The recommended road clearance in Victoria is 4.6m to deal with vehicles up to 4.3m. If the author doesn't have the English comprehension to figure this out from published material, I weep for the future.

While there is a discussion about land zoning that seems completely spurious, any discussion about the lack of warning road signs about the airport was completely absent. I'm not sure how much difference it would have made, but the interview with the driver suggests that he was oblivious to the airport so, maybe a couple of the standard yellow warning diamonds may have done something.

Why are we paying for this?

If you submitted a report like this to an academic institution it wouldn't cut the mustard. We are expected to believe that scientific investigation has taken place, so why shouldn't there be a factually accurate and grammatically correct report?

......!

No offence, but I wish that were true. At one stage in my life I had quite a bit to do with essays written by LLB students and later, with papers written by legal practitioners and social workers. I am no longer shocked by poor construction of sentences, lack of understanding of basic grammar, and inability to articulate thoughts clearly; but I am concerned that this is at least in part a consequence of the disjointed communication style now practised in social media.

The salient point of these reports might be obvious enough but I do believe that if there are consistent grammatical errors that this indicates a lack of thoroughness in the overall investigation. Just because these safety incidents are often repetitive in nature doesn't mean that a poorly written report is adequate.

Yep.

The report is the 'coal face' of all the work that happened prior. The interface between the investigators findings and we the reader. If the report reader caint understand or make use of the investigators findings then what is the point of the investigation ?

While a poorly written report might offer annoyance to the more learned around here they soon enuf see and understand the error and read on. To those like me with poor written and reading skills a poorly written report can be a confusing read that needs multiple readings to get a sense of the finer details. Whilst I'm a bit dogged and will persevere I would suspect younger pilots with the instant easy digest info mindset will simply not bother labouring though a poorly written report.

Here we go again. From a report issued today regarding a tailstrike to an A320 departing YMML:

"Good communication from the cabin crew alerted the flight crew that a tail strike may have occurred. The climb was stopped and a timely decision to return to Melbourne was taken which minimised the potential risk from damage caused by a tail strike."

"Good" communication? A "timely" decision?

These are judgements, ATSB. You are not there to make judgements. You are there to investigate and report. You just don't get it, do you?

This was my problem with their report on the Qantas A330. That report was full of glowing judgements about crew performance.

It's a "factual" report, FGD. It's a fact that ATSB made those judgements.

I was interested to read this newly minted tome from the ATSB regarding the Chieftan that bounced a main gear on a truck on approach to Barwon Heads.

https://www.atsb.gov.au/media/5773497/ao-2017-040_final.pdf

I struggle to find it cohesive, let alone reaching any sort of conclusion of any value.


Apropos of my earlier post I had assumed that reports, particularly from junior investigators, would be reviewed by senior personnel.

Where I have been in this (reviewing) role I have tended to allow some leeway to authors in their telling of the story. Another person's style is not necessarily mine, and if it gets the message across, with some gentle guidance, then why should I try and impose my use of the Oxford comma, for instance?

However this report suggests to me that maybe there is, at best, a flawed review process; certain aspects of it don't reflect well on the organisation, to my mind.

To this end I wonder if anyone knows what the investigation/reporting process is within the ATSB? Is there a published set of criteria?

FP.

Not to mention the factual error that the maximum vehicle height in Victoria is 4.3m not 4.6m. Which makes a lot of the reports discussion about landing approach angles valueless. The recommended road clearance in Victoria is 4.6m to deal with vehicles up to 4.3m. If the author doesn't have the English comprehension to figure this out from published material, I weep for the future.

Statements like this is why the ATSB really doesn't care what you think OA. From published material:

https://www.vicroads.vic.gov.au/business-and-industry/heavy-vehicle-industry/heavy-vehicle-road-safety/height-clearance-on-roads

4.6 m is correct for certain types of vehicles.

What I find amusing is that on a pilot's forum no one is talking about the pilots attempts to fix the increased rate of descent. But then again most of the harrumphing about grammar and they and their is from journalists and other pontificating professions.

If you knew me, you wouldn't question.

The Vicroads document recommends a minimum road clearance of 4.6m.

Vicroads don't get to regulate vehicle dimensions, thats the role of the RVCS section of DIRD that publishes the Australian Design Rules which are a legislative instrument. ADR 43/04 specifies a maximum height of 4.3m.

Overdimension is possible, but a completely different kettle of fish.

Even when its in writing you won't accept it.

The Road Safety(Vehicles) Regulations 2009 allow certain types of vehicles to operate up to 4.6 metres in height.
These include:
Car carriers
Hay trucks
Livestock trucks
Vans carrying light freight (separate information bulletins detail the
operating requirements for these types of vehicles)

All vehicles likely to be on a country road passing a rural airport. Your assertion was that the investigator hadn't done their homework and therefore the whole report is wrong.

If you knew me, you wouldn't question. All bow down:ugh:

All I know about you is what you post and from what I can tell you make statements that are incorrect. From your focus on the periphery of what happened and your lack of discussion on the actions and thought processes of the pilot I am assuming that you are not a professional pilot.

The ATSB's findings and "safety message" from the Barwon Heads incident suggest that they believe the pilot's non appreciation of ALA standards was the major factor.

This is WRONG. That aspect was not the major factor and I'm sure most pilots would agree with me.

The major factor was the flight path and the management thereof. This flight path was either chosen by the pilot, or was imposed on him by the circumstances, or was some combination of both.

The ATSB seem to believe that the runway threshold is the target of the flight path. This is not the case. Pilots are trained to touchdown at an "aiming point" which is some distance beyond the threshold. Passing over the threshold at 50 feet, on a descent angle of 3 degrees, for example, puts the aiming point about 300 metres beyond the threshold.

Why 50 feet over the threshold? Pilots are trained to do this because this is the optimum, according to landing performance theory. If this pilot had been conducting the approach in accordance with how he had been trained, and in accordance with his knowledge of landing performance, he would have been about 63 feet (19 metres) above the height of the threshold at the point he passed over the truck.

The aircraft was well below where it should have been. The pilot's poor management of the flight path had entirely eroded the safety margins that are provided by a normal approach.

This is the real "safety message" from this incident. Sure, ALA standards may have been a contributing factor, but only by a few centimetres.

Try again, ATSB.

Try that at places like Mabuiag and Darnley in the Torres Strait. Let us know how the aircraft recovery effort goes. :}

I thought the 50' over the threshold came from very early in the history of aviation where a particular military flying school operated out of an all over field with trees up to 50 feet at one end. That is what they used as a standard procedure and when it came to making regulations it stuck.

This thread is not really about landing technique. More about ATSB reports. Suggest you make your comment on the Barwon Heads PA31 thread.

Ahh no. Not sure how you would come to that conclusion anyway.

The strips are only 4-500m long, and in the case of Darnley, going in one of the directions is some sporty down slope. You do NOT want to be landing with your suggested aim point 300m past the threshold!
