Would this plane have flown?
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. 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...) -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

news:W9mUf.840188$x96.700068@attbi_s72... 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 [...] 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.

om... 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 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. , not having made arrangements/contacts with a local mechanic in case there were some kind of problem, etc. 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. 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. "People who can afford"? My understanding is that Robert wasn't the one footing the bill. Pete |

I don't think you would want to EVER disconnect a control surface. Do
others know more about this? |

I don't think you EVER want to disconnect a control surface or even a
trim tab. Any Aero engrs out there want to comment? |

Actually, now that I think about it, they had to be bigger than 1 inch. More like 1.5 inch. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

"george" wrote Nowadays I'd wait for repairs but a neighbour spent 5 years driving various two and four engined bombers over Occupied Europe and had a series of photos of just how little you -really- need in the way of contol surfaces 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. -- Jim in NC |

Robert M. Gary wrote: http://www.thegaryhouse.com/aircraftdamage/ 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 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. |

Flutter scares the crap out of me. 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. -- Dylan Smith, Port St Mary, Isle of Man Flying: http://www.dylansmith.net Oolite-Linux: an Elite tribute: http://oolite-linux.berlios.de Frontier Elite Universe: http://www.alioth.net |
