I often wonder how reliable the little plastic thingies are... how much time do they give etc? Most of the ones I have seen fitted are out of date.

Stalling or spinning into the ground is invariably fatal although I am not saying this is what happened in this case.
While that is the case in most stall spin accidents it does vary from aircraft to aircraft. There is a 4 seater Canard (Velocity)which on its test flight was stalled. The test pilot could not get the aircraft out of a flat spin and to save the only test airframe opened the canopy and attempted to break the flat spin by putting his body weight towards the nose.

This failed and the aircraft spun to the ground landing on a beach. The test pilot climbed out and the same airframe was repaired and used again.

As stated in a spin the vertical speed is relatively low compared to a dive. One witness described the engine sound like a high speed drill and the accident would look like a high speed dive crash.

I do not for a moment this was caused caused by CO poisoning because you normally get some effects from that, and of the three people aboard one would expect at least somebody to get a headache and have a moan about it.

I have a BW Gasalert CO detector. Great little unit. The battery lasts about a year and costs about £3. It even picks up the exhaust from the plane which landed before me.

Looking through all the threads and the possible time on type the pilot had on the aircraft, maybe a spin is a bit of a factor, but if he had the aircraft a long time and knew it well maybe not, think someone said he had a PPL for 19yrs? Could be more of a health problem leading to loss of control, especially if the passengers were not pilots. There is also the issue of mechanical problems, or structural, by that I means controls.
Whatever it was will come out in either a post-mortem report or from the aicendent report. Condolences to the families involved.

Statistically low-level stall-spin departures are not necessarily fatal but, being realistic, they are a common cause of fatalities. By type, the older "plank wing" PA28s, whilst not excessively dangerous, do have some history of fatal accidents of this nature (which, incidentally, was almost totally eliminated with the later tapered wing aircraft). This *may* be due to the aircraft's stall warner, which is very non-intrusive, unlike the relatively effective audio-warned of the later aircraft. Or it may be unrelated.

W.R.T. Discussion on performance. Whilst I'd agree that a Cherokee 140 is easily overloaded, an overload related accident is most likely to occur just after take-off, not some time later. Two people in the front and one in the back seat is unlikely to be close to the aft CG limit at any fuel load.



I was listening to the radio news driving home from flying yesterday when the BBC gave the names of the two passengers. A 10 year old and 18 month old child who will never see their parents again. This is the best reason in the world why we should all pay every attention to understanding and teaching the best practice in safety in our flying. I've spent a lot of my life studying and researching the causes of fatal light aircraft accidents; to some extent this has been reduced in the last year or so; this concentrated my mind painfully on the need for continued efforts in this area.

I'm astounded

Instead of temporarily removing the aircraft details from G-xxxx, the CAA have in fact already listed the owner/pilot as deceased....

Speechless :rolleyes:

Speechless
Why? The CAA website provides factual information, and this is a - certainly very, very sad - fact.

I feel sorry for the kids......

I recognise that the website is a factual database, and a good one at that - but today is a Sunday, and the CAA is the epitome of a bureaucracy. So it seems to me that some admin/techie person must have gone in to work and updated the website.

VFE 4th Jan 2009 11:01

Well said Genghis, it appears from reading this thread that much work still needs to be done in drawing peoples attention to flight safety given the desire by some to use the emotional aspect to stifle all positive discussion on preventing them.

Pa-28 140
 
I flew this type frequently in the late 1960's with a visual RED LAMP stall warning indicator. On one occasion with 4 on board the stall warning lamp came on at take off just as I eased back on the column. I had no idea why so pushed the nose down running into the X area for an extra 5 knots and very gently eased back the column. This time OK but I did not attempt a normal rate of climb until some time later. Subsequently I was told I should have had TWO stages of flap down rather than just ONE. This time I survived to know better.

However I was surprised at how heavy and "lumpily" the aircarft flew with four up and for finals I set up the aircarft some way out and longer than normal to get a feeling for the sink rate.

Nevetheless I never experienced any problems with 3 up and even although the aircraft had the "squared wings" never had any problems handling the stall even under blind flying instruction. I lovely little aircarft.

Maybe the intention is to prevent members of the media from mistakenly attempting to contact the aircraft's owner, which would only cause additional distress to his family. I do not think that the CAA have acted insensitively.

My thoughts are with the families and friends involved.

VictorGolf 4th Jan 2009 17:24

I expect I shall get flamed for this and I apologise for any thread drift but I have question. I was coming back from the Fly-In at North Weald today and chugging up "Mig Alley" between Luton and Stansted. Stansted ATIS was giving a temp of minus 2 degrees when I saw some lowish cloud ahead, fortunately off my track. The question is how quickly would a windscreen ice up in these conditions? I'm not suggesting for a minute it was a factor in this crash but I would like to know as I don't usually fly in such cold conditions. BTW don't engines perform better when it is cold.

IO540 4th Jan 2009 17:34


The question is how quickly would a windscreen ice up in these conditions?
Anything from not at all, to totally covered in seconds. It all depends on how much humidity there is in the air. I think bookworm is the one to ask how much icing potential there would have been on the day.

It's an interesting possibility - assuming the pilot was completely unable to fly on instruments.


BTW don't engines perform better when it is cold.
They do but in a PA28-140 you tend to be grateful for the smallest mercies, like having the prop rotating ;) So, not a lot of difference.

Shaggy Sheep Driver 4th Jan 2009 18:51

We all know that non-pilot witness statements are to be taken with a very big pinch of salt, but the consistancy of the reports (initially very low flight, high revving engine noise before impact, high speed descent, ground-shaking thump on impact, total destruction of the aircraft with no recognisable pieces left - and one credible description of a 'looping roll' [barrel roll?]into the ground) plus the video evidence of the accident site make me think this accident does not fit the usual GA accident scenarios. I await the AAIB report with interest. This one looks 'different'.

youngskywalker 4th Jan 2009 19:38

I often wonder how the AAIB cope with the amount of work they seem to have, I reckon they must be investigating at least one new fatal GA prang per month.

vabsie 4th Jan 2009 20:30

I was wondering how much press GA Accidents like these get in the UK?

If this unfortunate accident did not disrupt a rail track would it have made the BBC evening news?

I'm purely asking in order to try and gauge how frequent fatal GA accidents are? Is there an easy way to search on the AAIB Site for fatal accidents for a specific year?

And lastly .. terrible news of course and thoughts with all the family and friends.

cessna-kevin 4th Jan 2009 21:02

how many people really mean "my thoughts go out to the family" or waffle on about the incident without knowing the facts? i spoke with a friend of mine with whom ive flown on and off with for some years, who also said look on pprune and you will have countless comments of people getting at each other or trying to score browney points about the cause of the incident.this is one area of pprune that saddens me,i hope i am not alone and that many pilots out there feel likewise but cant be bothered to be caught up in this posting of a sad event.

On the contrary, non-pilots tend to describe what they saw. We pilots, I'm afraid, have a bad habit of trying to interpret what we saw and describing our interpretation of it - which can be much useful to an investigator.

i rest my case ,after the last post............i hope pprune changes for the better.

A and C 4th Jan 2009 22:53

I have to agree with Genhis, more than a few years back when a Helicopter crashed at EGTB (fortunally the pilot escaped with only bruses) the best witness to the accident was the guy digging the footings for the new toilet block!

He had no aviation background and just described exactly what happend.
