I was down in a remote area of Mexico this last weekend and a truck
backed into my aileron. I was lucky that the driver had a sat phone and
I was able to call an A&P to come down to Mexico and swap it for me.
However, all the local pilots, and the A&P who came down seemed to
think it would have flown ok as was. From a simply academic point of
view I"m curious what you guys think.

I wonder how the damaged aileron would have reacted to slow flight vs. a
little speed ...better or worse?

Just looking at the photo, I would have been concerned about the outer
attach point for possible post impact misalignment that might under load
cause an issue, but that being said, I've flown prop fighters on ferry
permits that looked worse off than this.
The bottom line is that you had a known damaged airframe and a take off
decision to make that involved a go/no go without looking inside the aileron
for hidden damage.
If the guys that won't be in the airplane are right, and you don't have a
problem, you're gold. If on the other hand, if the guys not going in the
airplane are wrong, and you do have a problem.........well......they're not
in the airplane......and you might be dead!
My decision would have been to have it looked at before I flew it out.

Most likely it would have flown fine--perhaps a bit out of trim.

The question one has to ask oneself in such situations is "do I really want
to be a test pilot?"

It is not impossible that the deformed control surface would have fluttered,
with possibly disastrous results.

Playing the odds, sure...pretty good chance it would've flown, and probably
with very little noticeable effect. But there's no way to know for sure,
short of a test flight. It could've been quite bad.

Also, while it's not clear the A&P who came to fix it bothered to check, I
would always be concerned at hidden damage. A relatively small force at the
wingtip can exert a much higher force closer to the fuselage, and of course
even out there at the wingtip who knows how the force of the impact was
transmitted through the airframe. I would be less concerned about the
damage to the aileron (which appears to be mostly cosmetic), and more about
potential damage elsewhere.

The classic rule applies: "when in doubt..."

My guess is yes - but seriously out of trim for sure. I'd do an empty
trip around the pattern for evaluation. Assuming the handling is
tolerable, load up but keep the speed down.

This is a case where it is really not correct to simply rely on an A&P
mechanic for such a decision. The training they receive doesn't really
include the consequences of aerodynamic variences although their
experience may be very valuable. It really is a situation where the
judgements and experiences of other pilots etc is as valid as any A&P
could give. I definitely don't want to put A&Ps down, but they don't
walk on water - they are only human in their ability to evaluate.

Jim Macklin
March 22nd 06, 02:04 AM
The damage appears to be confined to the trailing edge of
the aileron, so it would be out of trim. But the
reflections and paint otherwise look straight and
unwrinkled. A ferry permit could be issued for such a
condition and an inspection for range of motion, security,
etc signed of by an A mechanic and of course it would be
finally up to the pilot whether to fly. I would not want to
fly it IFR, most ferry permits only allow Day/VFR.

Since the wing looks good at the tip/aileron area, I'd also
want to see the wing attach points since the strength of the
wing and its lever arm would have a lot of force applied to
the spar points. I'd look for wrinkles, cracked paint along
the fuselage. I'd still look that over, just changing the
aileron doesn't complete the inspection.

Robert,
It would have flown, poorly. You would have had to hold right aileron to
keep it strait. High speed characteristics would be un-known.

You did the right thing getting replaced.

Nowadays I'd wait for repairs but a neighbour spent 5 years driving

You just never know about these "little bang jobs".
There's an old saying in the fighter business. Treat every pilot you meet in
the air as though he was better than you until he shows you by his actions
that he isn't.
Same goes for a damage decision. You should treat it as though it's serious
until it's proven that it's not .
This philosophy has managed to get me all the way through a career in one
piece. There just might be something to it :-))

There's no way I'd fly it. I saw a similarly damaged plane fly back to
it's homefield (against the advice from many) - and when it got back -
it was a *lot* worse. Considerably fluttering/vibration was apparent -
according to the pilot - in flight.

But he made it. He got quite a shock when he saw the additional damage
the fluttering had caused (dunno why he didn't put it down in one of the
many alternatives on the way).

One of the reasons I didn't want to try for the permit is because I
just don't know what the procedure would have been, but I expect it
would have taken months. The initial inspection would have had to have
been done by an A&E and then approved by Mexico City. However, then
comes the custom's duties, etc. Finally, I'd need an A&P to look at it
before I entered the U.S. (or right after entering, I don't recall).
So I kept very, very quiet about it. I didn't tell the Mexicans about
it and didn't mention anything to U.S. customs.I believe that
technically both the A&P and I could have both been arrested since I
believe it is totally illegal for an A&P to do any major repair without
an A&E present.

I guess I got lucky that the guy who hit me had a sat phone on him.
Otherwise I would have been faced with the decision. Either fly it out
of there as-is or abandon the plane there.

Well, at that point the insurance company owns the plane. Do you want

I'm not sure about the Mexican rules or even Customs duties
on bringing the repaired airplane back. But a visit to the
FSDO by the A&P before he came to Mexico, with the proper
details would have resulted in a quick issuance of a Special
Airworthiness Certificate [ferry permit] and the A&P would
make such repairs as needed before signing the logbook and
the certificate to make the flight legal. You would also
want to contact your insurance company because most aircraft
insurance policies are restricted to "when a valid standard
airworthiness certificate" is on the airplane. A ferry
permit is not a standard airworthiness certificate and your
insurance is not in force. That would be a violation of
Mexican law.
Also, not informing your insurance company makes it
difficult or impossible to recover damages from the truck
driver.

Since the airplane was US registered and the work was done
by a US A&P, the FAA would have issued the permit within a
hour. But Mexican labor law might have also required that
you hire a Mexican mechanic to supervise.

I hope you flew it back solo and sent the family by airline
or bus.

One thing to watch out for on seemingly minor damage near the outboard
edges of wings is a bent spar. Think of how much torque on the inboard
part of the wing that an impact to even make a small dent would make.
Needless to say, kinked spars are vastly weaker than unkinked spars.

Our club had a Cessna 170 - someone put the wingtip into a hangar at
taxi speed making a small dent in it. It also made a small kink in the
aft spar even though it was at low speed and seemingly only cosmetic
damage - the spar had to be repaired before the aircraft was airworthy
again.

I believe Highflyer has a story about hitting a wingtip of a Taylorcraft
on a pole at taxi speed - the damage appeared merely cosmetic but
the aft spar fractured in flight, which could have quite easily been fatal.
The torque from hitting the wingtip on the pole caused a compression
fracture in the wooden spar.

That would have been my take -- a little right wing down, and some
fluttering. Dudley made the right call, though. What you can't see is any
potential damage to the attach point.

That's easy to say now. However, that really means that you may never

Well the local Mooney service center just sent their estimate to the
insurance company. They are recommending a factory new aileron.
Although they are certified and equipped to rebuild them, they say
they've never seen anyone rebuild a Mooney aileron and get it straight.
Apparently the factory is able to do something the service centers
can't do. When I look at the aileron it looks like a bunch of ribs with
some skin on them. The service center is saying there are no ribs in
the aileron and the construction is different. In any case, I sure hope
my insurance company is able to claim against the truck's Mexican
liability coverage. It shouldn't be a problem but the total cost is
looking to be around $4K. The service center is also saying that there
may be a bent rod under the seat, but they haven't actually seen the
plane yet, this is just their Mooney experience. They don't seem
concerned about structural issues at all. The Mooney structure is very
different than a Cessna or Piper and considered much stronger (ever see
the picture of the entire factory floor assembly team standing on top
of a Mooney wing, two people deep?)

Is there actually an "attach point" in the normal sense? I've never
taken one of these apart but my undetstanding is that its a one piece
solid wing and the body of the plane rests on top of the wing. I've
seen the wings removed and they are one solid piece (not two wings like
a Cessna).

That's easy to say sitting here but not so easy when you're there. The
concequences of that are 1) You may never see your bird again and 2)
Rather than a 2 hour flight back to the states you are looking at 2
days of Mexican dirt roads blowing chunks the entire way.

The insurance co's attitude was "spend what you have to, do what ever
you have to" to get the plane out of Mexico. If a pilot leaves a plane
in Mexico it can take months to get it back. The Mexican gov't has a
real hard time with pilots exiting that are not the pilot who flew the
plane in. Also, they know there is money in fixing airplanes and they
want to make real sure they get a piece of that. Everything in Mexico
requires lots of paperwork and every paper needs lots and lots of
stamps

That may all be true, but the FAA does have the ferry permit
to allow damaged airplanes to be flown, solo or required
crew only. Your insurance company has a contract to insure
your airplane if you operate it in accordance with the FAA
regulations.

Purely from an academic standpoint, I'm curious why people go into remote
areas of a foreign country (particularly one like Mexico) without some way
of calling for help if they get stuck, not having made arrangements/contacts
with a local mechanic in case there were some kind of problem, etc. People
who can afford having an A&P come down to Mexico to fix a problem ought to
be able to afford a little planning ahead for eventualities just like this
one. Academically speaking, of course. :)

The insurance co was pretty clear that they did not want me to wait
around for the paperwork process and wanted me to get it back to the
U.S.. The longer you wait around, the more likely the Mexicans will
notice the plane is damaged.

Having a local mechanic work on your plane only solves 1/2 the problem
because the plane is again illegal as soon as you get back to the
states since you would need another log entry from a U.S. mechanic. I
think its better to skip the Mexican mechanic and just have the A&P do
the work and don't let the Mexicans find out.

Nobody can really tell just by looking at the picture. I would want a
look at the aileron attach points and control linkages - but that would
be a flashlight-and-mirror deal. If they were OK, I would cheerfully
sign the ferry premit and fly it.

The damage to the aileron is superficial. Stay in the green arc and it
will be OK. Do I know that beyond a shadow of a doubt? No. But as an
A&P and engineer, I consider it so close to certainty that I would be
willing to take the risk.

For sure. At OSH '04, our tent -- with 1 inch aluminum poles -- blew over
onto the wing of Atlas, our '74 Piper Pathfinder.

Those very stout tent poles bent like pipe cleaners over the trailing edge
of our right aileron like butter -- with NO damage to the aileron.

If a one-inch-thick pole can break across the trailing edge of an aileron
WITHOUT inflicting damage, just imagine the impact it took to inflict that
kind of damage to your aileron. I'd check the wing spar and attach points
very carefully.

(Incidentally, our '75 Warrior had very similar hangar rash on the aileron
when we bought the plane in '98. Our A&P signed it off at the pre-buy
inspection, and we flew it that way for several months, until we could
afford to have it rebuilt. Never had a problem...)

I thought you said they were "1 inch aluminum poles".

Not to discount your point about the potential of harm to the interior wing
structure (which is valid IMHO), but I'll bet you could take one of those 1
inch aluminum poles and easily bend it over your knee.

What would you suggest? Satellite phones are pretty much the only solution
that I see and they are quite expensive. They are also a relatively recent
invention (especially with respect to consumers like us), and somehow people
managed to get by without them prior to their availability.

This is an even more bizarre thought, IMHO. Do you arrange for a local
mechanic at every location to which you fly? I sure don't. I doubt many
pilots do.

Nope -- I tried.

Actually, now that I think about it, they had to be bigger than 1 inch.
More like 1.5 inch.

THEY had no choice, but to fly back home, while they were hit over enemy
territory. This fella did have a choice.

My take on it? He got lucky, and I'm glad he did.

I would say the chance of having a problem is low, less than 10%, most
likely. That means if 10 guys got hit like he did, one would not make it
home. Put in those terms, would you want to be that 1 out of 10? Even if
it was 1 out of 100, it would be too high, when there is a choice.

If it were me, I would have done as detailed inspection (removing access
covers, whatever) as possible. Perhaps, I even would have disconnected that
side at the yoke, or first belcrank, and bolted that aileron stationary.
Flutter scares the crap out of me.

Whatever, I would not have made any decision's based on what the insurance
company said.

I would not have felt qualified to determine whether it was flyable or
not, so I probably would not have flown it without getting an opinion
and a ferry permit from an A&P (and I am not above making the A&P fly
with me). My main concerns would be weakened attach points and possibly
some sort of flutter induced by disrupted airflow over the aileron.

I would strongly doubt (based on what I know) that there was even the
remotest chance of flutter. From what I understand, flutter would
require the flexing of the wing structure in such a way to cause the
whole thing to oscillate. This happens with experimental airframes (or
used to happen) because the whole surface or wing would warp under
aerodynamic loads in such a way that you'd get the oscillation. A dent
in a Mooney aileron isn't going to cause that.

Yes it could - seen it for myself first hand - significant further
deteriotion occurred in-flight as a result of the flutter (that the
pilot could feel) - the pilot was very relieved to be on the ground
again - and won't be repeating the experience (why he didn't choose to
land at one of the several alternatives, we'll never know).

OK, I thought this requirement came from manufacturers service letters and the

Here's a quote from http://www.avweb.com/news/maint/182829-1.html "Getting Good
Paint" by Paul Bertorelli:

"Guenther and better shops insist—rightly—that controls be removed, stripped,
inspected and, most important, rebalanced after painting. On some
controls—Bonanza ruddervators and Mooney ailerons—this is a critical task and
shouldn’t be skipped. But it should still be standard on all aircraft. Guenther
goes so far as to record the balance data in the aircraft logbook, along with
the signoff for the paint itself."

which makes me think this is not a general requirement or practice.

nrp
March 23rd 06, 03:45 PM
Flutter is determined by the torsional stiffness (and mass) of the wing
section. In this case, that did not seem to be compromised - i. e.
there were no diagonal wrinkles across the wing panel. If there were
diagonal wrinkles, flutter would be a real possibility. But dropping
the airspeed greatly helps the flutter margin, just as increasing the
max speed quickly reduces the flutter margin. I understand that during
each new aircraft's flight at the factory, the test pilot must dive it
to 110% of the indicated red line speed. The survivors are certfied.

There were diagonal wrinkles across the aileron panel, but I don't
think the aileron in itself can flutter. The question in this case
would be the aileron control integrity. Someone earlier suggested
blocking or locking one aileron. That could have all sorts of
interesting changes and very definitely I would not recommend.

That is exactly how I felt (although I was less concerned with the
permit itself). I was getting lots of advice but it felt good to have
an A&P come out and give me his opinion. It would have been nice to get
the opinion of an aerospace engineer but I wasn't going to hold my
breath for that. I did have the A&P come with me on the test flight
after the repair before I put the family in the plane. My main concern
had also been flutter resulting from the uneven surface.
My broker seems to believe that it would be very unlikely that this
will effect my rates in the future. I"m hoping that they are able to

how often people drop their plane off for annual and the mechanic
borrows parts off it to retrieve another plane without the owner ever

It is. Most all manufacturers provide control surface balance requirements.
Even the Cessna 150 requires it. I also believe it is in the FARs.

Flutter is caused by imbalanced movable surfaces. When the
plane moves the moment arm of the surface causes deflection
of the surface.

Jim,

I'm not sure what type of stupid statement you are trying to make. The
plane was fixed (minus mismatched paint). How many years do you
normally require a plane sit idle after the A&P repairs the plane
before you fly it??

-Robert

Jim Macklin
March 23rd 06, 06:22 PM
Was it repaired and completely inspected or were more
repairs done on return to the USA? The indications that I
had from the thread was that more repairs/inspections were
done on the airplane after it returned to the US. Yet you
carried your family after major repairs caused by damage.

Glad you got away with it, but what would you have done had
the bell crank on the aileron been damaged and stuck the
aileron full up or down? What would have done if something
else was hidden in the controls that was not repaired? You
obviously had a question, why else did you start this
thread?

FAR requires a test flight after repairs and that you, the
pilot doing the test make a logbook entry, right after the
A&P release to service, before any passengers are carried.
Without a ferry permit [special airworthiness certificate]
the A&P can only return the aircraft to service if it is in
the same condition as a "new airplane" or all repairs are
completed. If you are stopped by the FAA on a ramp check,
hope all your paperwork is perfect.

Quoting from the original post "I was able to call an A&P to come down
to Mexico and swap it for me." Sadly, the other Mooney owners wants his
back (go figure) so yes, more repairs were also done back home (like
ordering a factory new aileron for me, paint etc). Yes it was
inspected in Mexico by the A&P doing the work and all wing panels
relevant to aileron control were removed before the A&P got in the
plane with me and we performed the test flight. I honestly don't know
what else to do with regard to inspection other than having had the A&P
look at it. I could ask Mooney if they want to send an engineer down
but I don't think that is going to happen.

Jim, I'm still highly offended by your comment about my family.

nrp
March 23rd 06, 06:39 PM
But I understand flutter also relies on the original torsional
stiffness of the wing being preserved. That if it is not (i. e. a
wrinkled wing skin) the flutter margin is reduced. Might even a
properly balanced control surface still flutter if the primary wing
stiffness is compromised? or is the control surface CG the only
determining item? THX

IMHO you did everything that could have reasonably been expected.

Jim Macklin
March 23rd 06, 06:53 PM
Then you answered the question, IF you really had a complete
repair and the A&P did make a "return to service" entry. If
he did all that and you did a test flight [you really should
not have carried a passenger, which the A&P would be] and
made the pilot's return to service after test flight, then
what was your question, should you have just flown it away
without any work/inspection or repair?

As for your family, my comment was about your judgment, if
you want to substitute three strangers from the beach,
that's fine with me.


BTW, since some FAA types read these groups, they have your
N number.

Wing stiffness has more to do with control reversal, flutter
has to do with harmonics and balance.

If I had a question about a control surface and I had to fly
the airplane, I would limit speed to Va so that even a full
deflection of the control would not break the airplane.


I've seen pictures of a C210 [old plane with struts] that
took off from a strip near Tulsa with just a little ice on
the ailerons. I got to cruise speed and crashed shortly
there after, the outer wing panels looked like a Navy
fighter with the wings folded.

Jim, again quoting from the original post..
"From a simply academic point of view I"m curious what you guys think."
I was just curious how it would have flown since I obviously did not
fly it.

Again, I was very offended by your comment.

Flutter can also result from unusual airflow exciting a surface (such as
the rather large dent in the aileron tip). It is a function of
stiffness, true airspeed, balance and external excitations.

The owner did the conservative thing -- after all his insurance company
was there to stand behind him. Yes -- the whole thing was obviously a
major PITA, but everyone came out fine. Congratulations!

That it may be illegal and that it needs another log entry are two separate
issues. There's also nothing wrong with using a Mexican mechanic if he/she
is an FAA-certified A&P. You can download the airmen database from the
FAA.GOV website and check for certified mechanics living there (as well as
in any other country, they even separate the files for you, domestic and
foreign), or you can go to places like...

http://www.landings.com/evird.acgi$pass*81558983!_h-www.landings.com/_landings/pages/search/certs-ap.html

....and search for COUNTRY = MEXICO and off you go.

Also, if you do a little bit of research you'll find this interesting
document...

http://www.bajabushpilots.com/news-pop.php?NewsID=44

....which contains this interesting little tidbit of useful information:

"2) A&P mechanics working on US aircraft in Mexico
Requested by the BBP (Baja Bush Pilots) at the meeting, the DGAC (Dirección
General de Aeronáutica Civil), after consulting with their legal persons (at
the meeting) indicated that this requirement was not a rule or law and that
US A&P mechanics can work on US aircraft in Mexico without the presence of
or signing off by a Mexican A&P. This major change will make repairs much
simpler and less expensive for anyone who has a problem in Mexico. The DG
indicated that he will be sending a message to all ICAO airports addressing
this situation this week."

All of this is academically-speaking, of course. Don't take it personally,
I'm just trying to show the benefits of doing a bit of googledigging before
heading off in that nice Mooney of yours to a remote location in a foreign
country.

There are other solutions, such as portable radios of various types, as well
as arrangements to have someone come down to the location if you haven't
been heard from in x number of hours or days.

What is bizarre is reading what I said and translating that into "every
location to which you fly." That is absurd. Note that the original post
mentions a REMOTE LOCATION IN MEXICO. Enough said.

I didn't get that at all from what I read. Did the insurance company pay for
the A&P coming down to the "remote location" in Mexico to make the repairs,
including the cost of the parts? The point is there are quite a few A&P's in
Mexico proper, FAA-certified. Just because someone is Mexican doesn't mean
he/she can't do repairs on N-reg aircraft.

Been thinking about a test flight to test any airplane after
such damage repair, before carrying passengers.

A full range of control inputs at no more than Va for the
weight, followed with autopilot operation. Then in small
steps of increasing speed up Vne with moderate control
displacement.

No, what is bizarre is having two people not understand what you meant, and
blaming both of them rather than considering that your words might have been

They were not.

"Purely from an academic standpoint, I'm curious why people go into remote

Not a word about "every location to which you fly." Very specific mention of

You have no desire to see the truth, because it implies defect in your post.
However, the fact remains that the defect exists. The proof is in the way
your post was read by others.

As far as your claim that you were clear about "remote areas of a foreign
country" go, that clause was interpreted by both me and Steve to be
connected only to the clause immediately following, with the subsequent
comma marking the beginning of an entirely new clause.

As I said, it is bizarre that you would ignore the ample evidence of the
ambiguity in your post, and continue to insist that it was not.

I suppose. But the dude in the truck was there, at least he knew he could

Typical. Don't like the message, so shoot the messenger. How mature. It
