Light aircraft down near Oban?
 
Just reported on BBC News.

No further details, other than it appears to have been flying from central Scotland to Tiree?

Jan Olieslagers 4th Apr 2015 17:58

Not more info as yet, but it is sure to come up.

Noticed a Bristow S-92 SAR bird heading in that direction at about the right time - headed back to Inverness 1 1/2 to 2 hours later.

piperboy84 4th Apr 2015 20:24

If the SAR choppers go home, do they come back or is the search continued with ground personnel only ? What's the SOP

I heard a helicopter around this afternoon then saw the Oban lifeboat at the top of Loch Etive on AIS.

If the weather was similar to that in the news photos of the search, I guess this could be either - VFR flight trapped between terrain and dropping ceilings; or IFR forced to descend blind due to mechanical problem. I guess we will find out eventually.

SpannerInTheWerks 6th Apr 2015 09:48

Strange that no one seems to know anything about the flight?

A sad occurrence

SpannerInTheWerks 6th Apr 2015 10:03

Very sad indeed.

9 lives 6th Apr 2015 11:00

This is sad all the way around. Following an extended family tragedy, in which two cousin kids were killed in a car accident on the way to a family Christmas, I rethought my airplane as a mode of family transport to "big" events. My personal choice is to reduce the use of my airplane, and greatly increase my personal minimums, when seasonal or big family events are involved.

When my daughter was married here at home, not only did I not fly, I blocked the runway with my plane so no one else could either. An aviation accident was not going to be a memory for her special day.

I'm not trying to allow my flying passion to appear dangerous, but the reward vs disappointment ratio can really change for a lot of people, when X day becomes the life long memory of the day that A+B were killed. If you're flying there to surprise them, you did not fail to surprise them if you wisely turn back for poor weather - they weren't expecting you anyway. If they were expecting you, they'll understand. If you have to be there, going much earlier, or by a more common means is worthy of consideration...

Munnyspinner 7th Apr 2015 12:07

Wise words
 
Thank Step turn
A useful reminder that press-on-itis, get-home-itis are all too often a contributory factor. We can all fly below minimums but never without eroding safety. I flew a gtf in very poor conditions having called it off. My examiner confirmed I had made the right call then we flew. It was perhaps just on the right side of marginal and he was a very experienced ex military CPL/IR. It was the most useful thing I have ever done. If the weather is marginal for flying - don't fly. If the cloud base is lower than the surrounding hills - find another route, drive or look at the forecast for the next day! Hindsight is a tool only available to the living. Two lives cut short. So sad.

I am still amazed that people don't use the performance of a flying-machine to climb above inclement weather. It seems so logical to use the 3 rd dimension to avoid interaction with Terra Firma.
(no, I'm not a pilot, but have some experience of light aircraft.....this was not a low-performance Microlight.

A very sad waste of 2 young lives.

ecosse 7th Apr 2015 21:47

Low powered microlight?

power to weight ratio and climb rate of just about any micro would be as good as any cherokee? I stand to be corrected.

A microlight could land on a field just about anywhere but a pa28? not so sure.

anyway looking at the weather and where the flight was headed I would not have attempted this flight. Not a chance, certainly more chance of putting down a microlight somewhere if weather gets bad.

Very sad..

as was the other incident over the water today.

:ugh:

Cockney Steve: This being a public forum of course you have every right to comment.

The wisdom of doing so is another matter.

But there are so many variables that we should all wait for the AAIB report as the team making the report , unlike you, will probably contain a pilot and will investigate whether , for example, the crash a/c pilots were IMC qualified and did indeed attempt to climb above the weather only to be brought down by ice:

There are many tragic possibilities.

Nobody knows: leave it to the experts.

Not quite sure how that is to be achieved if the icing level is below MSA.

(I didn't go outside the circuit that day because the forecast icing level down here was only about 1,000' above MSA and I wasn't comfortable with that. Someone who understands met a lot better than me might have come to a different decision.)

CS, as you earn the privilege to fly, and gain experience, the many possible and probable reasons for not flying over weather, in most GA aircraft, will become apparent, and your amazement will recede.

Many of us here have flirted with flight out of VMC when we should not. Now we actively encourage other pilots not to go there, until properly trained, and flying a suitable aircraft. The key to GA safety is NOT using the 3rd dimension when weather gets poor, return from whence you came on the 2nd dimension you came on! If you are flying the valleys, there is no GA aircraft with the performance to safely climb out within the valleys, to safe airspace above - If the flight is not planned to be flown in IMC from the beginning, changing to flight out of sight of the ground along the way is probably very unsafe.

Some GA type destinations cannot be reached at all with a flight planned in instrument conditions.

piperboy84 8th Apr 2015 04:13

Damned shame for the young couple just starting out in life.

As a pilot who regularly flies in this area and whose favorite journey is taking the boat on many occasions from Connell bridge up to the logging camp at the very end of loch Etive I can assure you it is very hostile terrain to attempt a forced landing regardless of weather. The glen walls on the part of the loch that doglegs north are pretty much sheer from about 800ft down to and below the surface, my depth gauge was showing at least a hundred feet close to shore and could not measure the bottom in the middle.

Does anyone have the weather for the day in question?

adambsmith 8th Apr 2015 07:37

This is horrible news.

When I saw the 'selfie' of the two people in the Daily Mail's report, it reminded me of a very similar selfie I have on my phone of me and my wife. I then started to question whether I wanted to continue flying with my wife at my side or at all.

I realise there may be other factors (and we should wait for the AAIB report) but if the met on the day (see bottom of the first page) had shown up on my iPad that morning I just would not have bothered to go to the aero club let alone climb into a PA28.

I await the accident report with interest - not from a morbid point of view but wanting to learn what exactly went wrong.

maxred 8th Apr 2015 09:36

Sorry for the families of these two people.

Ecosse, the weather you gave was for Oban, not Tiree, not sure what it was at the destination, but it can be very localised weather. Overcast at 1500, with broken at 1600, can mean anything. We do not know if this pilot was instrument rated/IMCr. If so, a cruise above at say 3k, would be pretty easy, IF the weather at destination was suitable for VFR let down. The report will cover it all. I advise,and stress to all, that if flying in UK, particularly Scotland, some form of instructional Instrument flying should be done. Dundee to Tiree is a direct route, MSA should be in region of 5000, so.........VFR at low level, is precisely that, VFR. If a wall of crap was sitting around Oban, they should have gone round, turned back, or headed South and let down over the water. We were not there so... and easy with armchair hindsight to make comment. The report may well be predictable unfortunately.

Unusual Attitude 8th Apr 2015 09:55

Tiree weather for the day, pilot was IMC qualified and I'd expect with the forecast en route he would have planned to use it:

I departed Perth a couple of hours earlier that day and the cloud base in that area was around 4000' though reducing significantly inland, forecast to the west was guff, freezing level if I recall given as 2-4k. I was headed south thankfully but even that was rubbish south of Edinburgh and I had to route along the coast.

maxred 8th Apr 2015 10:19

Thanks UA. That is a no go in my book, and would suggest most peoples. It was not even predicted to improve. It just is so sad when peoples lives are lost when based on a weather decision, where everything is telling you get the ferry.

What a shame; however 'see and be seen' has always been a good motto, especially flying light aircraft.

I had flown HF a number of times as an instructor when it was at CVT (EGBE) in the 80s:hmm:

Regardless of ratings, EGPO doesn't have any published procedures and the METARs seem particularly low for a DIY approach. So to that extent, I would be a bit surprised if he was rated. However, as has been said, the facts will all come out in due course with the AAIB.

SpannerInTheWerks 8th Apr 2015 13:31

If this was a club-operated aircraft who signed them out - surely with the weather forecasts available and the route known it was a 'no go' from the start?

As MaxRed stated:

That is a no go in my book, and would suggest most peoples. It was not even predicted to improve.
If it was a privately operated flight, it's sad that no one questioned the viability of the flight and/or had a quiet word in their 'shell-likes' when they booked out. All good advice in hindsight I know.

There are many issues here it would appear - not least IMCr v IR, MSA, published procedures, freezing level, TAFs and actuals ... the list goes on.

It's one of those accidents which makes you feel that the system's failed them somewhere?

Unusual Attitude 8th Apr 2015 13:54

I can assure you the pilot was IMC qualified, and it was his own aircraft, not club owned.

I'm not going to speculate as to what I think happened, merely stating that the weather was guff at the time which is apparent from the historic METARS. These are easy to read in hindsight and the TAFs may have shown something different but from memory of my brief that day the Form 215 showed crappy weather to the west, a nicer patch over Eastern Scotland and either a warm or occluded front out to the east moving west at about 10-15kts. It may have been the pilot thought he saw a window in the afternoon where the nicer patch would be over his destination, as it happened the winds aloft were not even close to forecast that day.

I'll leave it for the experts to figure out.

dont overfil 8th Apr 2015 15:23

loganair cancelled their morning flight to Tiree due to the forecast.

However, the Tiree weather had nothing to do with what happened as he was still 60 nm away and in the cruise.

Aircraft being taken off the mountain today to be moved to Farnborough.

Unusual Attitude has the basic facts correct. Freezing level in the area was forecast to be +2 at 5000ft. I would not trust that to be accurate but he could have been above cloud. 10 miles west of Dundee he was climbing through 3700 ft and VMC.

maxred 8th Apr 2015 15:42


However, the Tiree weather had nothing to do with what happened as he was still 60 nm away and in the cruise.
Agreed, but given he was flying Dundee - Tiree, it figures largely in the decision to go, or not, as the case may be.

Maybe his engine failed, no one knows.

piperboy84 8th Apr 2015 16:54

The press reported that "radar coverage was lost" if this is correct I assume he must have been at least 5k to have been picked up which may have put him VFR on top which would be more likely than trying to stitch his way thru the low level clag with high mountain tops. As a previous poster implied it could have been a multitude of causes or a combination thereof. Either way it's a tradgedy.

Maoraigh1 9th Apr 2015 09:06

From the Oban Times:

The plane was seen going down behind the hills at a steep angle by two separate hill walkers in the Ardmaddy area,who reported it to emergency services.
This appears to have been loss of control at altitude - not scud-running. As there is no fuel at Tiree, they would have had fuel to return, and probably divert to anywhere in Scotland. The decision by an IR(R)/IMC rated pilot to fly the route does not seem unreasonable.

TAF COR EGPU 041206Z 0412/0414 29009KT 9999 BKN015 TEMPO0412/0414 1200 DZ BR BKN002
Pilot error does not appear to me to be the most likely cause. Airframe break-up due to severe turbulence/overspeed?
Overspeed reulting from A/H failure in cloud? CO affecting occupants?
I assume they would have been able to recover from a spin in the VMC conditions where the hillwalkers saw them.

airpolice 9th Apr 2015 11:01

Or a loss of control due to Icing / Airframe failure / Pilot incapacitation, the list is huge.

Once the AAIB have trawled the wreckage we might get a GoPro style FDR/CVR to tell us what went wrong, or we might never know.

As for a not unreasonable journey, Loganair cancelled their trip that morning, due to Wx.

I agree that a report of the aircraft descending into the ground, as opposed to flying into it more or less level, is interesting information as to the conduct of the flight. Scud running is less likely to result in steep descents - 'cause you're not high enough to do it :uhoh:

Any of the quoted circumstances (other than the CO) would happen only as a result of failure to maintain speed, and/or attitude. That would take us back to pilot actions. An airframe will not break up in turbulence, if the aircraft is flown at a margin slower than Va. A spin will not be entered if speed and attitude control is maintained. A/H failures happen, but can and should be managed.

It is possible for a pilot to loose control of at aircraft in IMC or no practical vis conditions, with JFK Jr. being one of the more memorable examples.

Well, if I wanted to fly a helo off a nearby ship into Tiree that TAF might seem reasonable. But it doesn't seem so reasonable given where the flight was coming from and the dirty great mountains they had to negotiate. One would expect a route brief indicating somewhat better conditions to that along the way, and no doubt the experts will be looking at that as they try to figure this one out.

gasax 9th Apr 2015 19:25

To the east of Ben Cruachan it is highly likely that the weather was perfectly reasonable VFR. In the lee of that ridge running down the east of Loch Linnhe it would have had a very low ceiling. To the west more typical of the Tiree conditions

Over Tiree where there is a single area of high ground and the rest of the island is about 20ft high it would have been reasonable to descend over the sea and sneak in. These conditions are not unusual on the west coast and it is possible the pilot was familiar with them - or equally they were not. But being natives of the island and IMC rated? Likely they were familiar with the typical conditions.

funfly 9th Apr 2015 20:53


I am still amazed that people don't use the performance of a flying-machine to climb above inclement weather.
When I had just learned to fly but did not have an instrument rating, I flew into a cloud wall that I did not see.

Engine to full, 180 turn and climb as fast as I could.

When I cleared the cloud in less than 1 minute I found myself very close to the ground and at a peculiar angle. It was a close thing and made me quickly get my instrument training but it does illustrate that it's not as easy as 'just head upwards'.
