High time airframe question

It is my recollection that piper wing separations tended to occur on hightime airframes that also spent considerable time doing pipeline patrols. otoh - 11,000 hours on that warrior is how many hours per year? -- Bob Noel (goodness, please trim replies!!!) |

I would personally be much more concerned about an aircraft that's sat around in some field with grass growing around it for years on end. High time generally means the aircraft has been regularly flown, well maintained, and upgraded for it's entire life. My airplane has almost 9,000 hrs and I'm not at all worried about it. I know a guy that owns a 172 with over 17,000 hrs on it and it's still going strong. I think that's a concern in the industry though. As our fleet ages we may find that planes will start falling from the sky at some point. Boeing puts limits on how many cycles a plane can have. It would make sense too that a spar can only flex so many times, wouldn't it (I'm not metal expert though)? Perhaps there is such a point, but I don't believe that point is within the realistic life of a small GA aircraft. The limit Boeing puts on aircraft will be in the neighborhood of 40,000 hours or more. Even at that you have a lot of 727s and 747s still flying at well over 70,000 hours. You're also talking about aircraft that endure extremes of pressure and temperature on every flight and routinely penetrate severe weather that no pilot of a small GA aircraft would purposely go anywhere near. Corrosion is a much greater threat to GA aircraft than metal fatigue. |

High time airframe question
In this market why would you screw with an airframe with that high of a
total time? Good point. A lot of folks are practically begging to sell right now. It's a great time to be a buyer. -- Jay Honeck Iowa City, IA Pathfinder N56993 Ercoupe N94856 www.AlexisParkInn.com "Your Aviation Destination" |

My partners and I are looking at a warrior with over 11,000 AFTT. In this market why would you screw with an airframe with that high of a total time? Probably because high time airframes offer an even better value in many instances. Also there's lots of high time airframes out there which are very well equipped because those who were in them spent a lot of time and they could justify costly improvements. Here's two aircraft simularly equipped: This one is listed for $39K http://www.aso.com/i.aso3/aircraft_v...raft_id=114817 This one is listed for $89K http://www.aso.com/i.aso3/aircraft_v...raft_id=115832 Both aircraft are the same age, carry the same weight, and go the same speed. One is $50K cheaper than the other. The 2nd one might be in a little better shape cosmetically and perhaps even functionally, but not $50K worth. If I were in the market for such a plane, I would be more inclined to buy #1 and that's even knowing it almost certainly spent a good part of it's life as a trainer (notice the wear on the rightside yoke). |

I think the greater issue with airliners is the pressurization/depressurization cycles, not the landings.- That's just another way of saying metal flexing too much. We have flex in our metal parts too. That's the point. -Robert |

True, except that about all of the nice 182RGs seem to have that butt-ugly brown/orange interior with orange or brown paint! Man that is ugly... Matt |

Flying straight and level for long periods and mostly well under gross. What am I missing? |

Nap of the earth flying, jinking, turning and diving and climbing. I believe they have to stay close to the pipeline for their sniffers to work. That would put more stress on the airframe than training, except for the landing gear. -- Jim in NC |
