Subject: | AOA probe design |
Folks,
I am looking for a sensible AOA probe to feed my Dynon D100. The
Dynon probe is ghastly - very big and heavy so I won't use that.
I can't see what's wrong with a small, light weight probe based on
the same principle, ie an angled face with a hole in it. Has anyone
else designed their own and if so how well did it work?
Anyone know of a good off the shelf probe suitable for the Dynon?
Many thanks
Willie Harrison

Replaced the wheel barrow tyre with an Airtrak prior to first flight, there
was clearance between the tyre sidewall and forks then, albeit small, now
find after 7 hours and 24 cycles the tyre is now lightly rubbing against the
forks.
This subject, from memory has been raised on here before, cannot fully
remember the fix, would someone be kind enough to reiterate their proven
procedure.

I don't know of an off-the shelf probe, but I wonder if something
like the attached PDF would do the trick. Any half-competent machine
shop should be able to produce a similar item, even scaled down a bit
if thought desirable.
I found the file in my "AOA" folder and I'm afraid I don't know where
I got it, although the "airsoob" part of the filename is probably a
clue.

Rowland

Jim & Heather.
I've had no luck with any of the flexible plastic tubing.
As far as possible, I have replaced it with auto fuel injector hose.
Aircraft Spruce list clear PVC pipe, used in Quickie as fuel level
gauge, p/n 03-54100,
however the diameter is larger, and I could not see an easy way of
plumbing it in
without risking a further source of fuel leakage.

After reading the report I am left not fully understanding which came
first.....thus causing the second.
Did the rear lift/drag pin of the right wing fail, causing enough up and
down movement to overstress the tailplane enough for it to disengage from the
tailplane drive pins, causing significant up and down gyrations to cause the
further and final failure of the right wing?
Or did the tailplane disengaging cause the failure of the right wing rear
lift/drag pin?

Rowland,
That could well be a problem.
There actually a loop of wire in the back of the meter which you
cut to activate the timer. You could splice in a switch to detect wings
on, airspeed>60, etc. If trailering is frequent though, I'd look for a
different solution. N224xs lives in a hangar far from my old
earthquake shaken home of KSQL

I think the report is very detailed. The failure of the drag pin caused the
whole scenario. The tailplanes had nothing to do with it. But who knows, i

en possible ?

Mike,
I know that for some time now the AAIB and the PFA/LAA have been looking
at the failure of the right hand wing rear drag pin being the cause of
the accident and you can certainly read that into the report, but I
agree that it does take some reading to figure it all out.

I don't see how failure of the drag pin leading to flap flutter and

I think that was the underlyng conclusion (i.e. they don't know)
although the BBC has interpreted in its news 'report' that it was the
wing pin failure that caused the aeroplane to crash; which in a way is
true, but possibly an oversimplification.
The AAIB report has the flavour of having been poorly drafted, then
amended a number of times by a number of other people. Either way, the
report uses the would "if" a lot of times and the word "would" where one
would expect "could". But otherwise it would read even more
speculatively.

Duncan, I disagree. I think the report reads as a very well thought out
account of detailed detective work, and that the conclusion that the wing
lift pin failure was the primary cause is entirely convincing. I would
rather have believed that the tail was the primary problem, but the lack of
metallurgical or other evidence of tailplane flutter, together with the
findings of the opened up holes in the outer alloy plates securing the Right
lift/drag pin, is enough to convince me.
Having said that I don't feel that a prolonged discussion of the
minutiae of the report will be a great help to William and Paul's relatives.

I don't believe that the experts, the AAIB, publish these reports lightly -
and I certainly don't think that their findings should be queried on this site
by a lot of people who think they know better..
If you want to talk about it do it verbally, but out of respect for William

I visited the AAIB a few weeks ago and by chance got to speak to the
lead inspector on G-HOFC. He was very clear that it was the wing drag/
lift pin which initiated the break up and they had abandoned their
earlier hypothesis that the tail failed first..
Also, I'd have to add how utterly sobering it was to look at the
wreckage - if you set out to cut a Europa into so many pieces with a
chainsaw it would be a day's work.
