The fact that the plane had an estimated 25 hours since new indicates strongly that it was the standard 25 hour inspection. George Patterson There's plenty of room for all of God's creatures.

Anyway, that was just an example. It might have been the AI portion of the display, instead. If I had to bet, though, my money would be on simple spatial disorientation. Until you've had it happen to you, you just don't know how easily you can become completely fuzzled at night if you're not on your guard. -- Dan C-172RG at BFM |

As I recall, there's not much to it - mainly check a bunch of stuff to make sure it's still firmly attached and change the breakin oil out if that hasn't already been done. There's another one due at 50 hours since new. That would also explain why he was flying it elsewhere for the work. Bet that was the dealer who sold him the plane.

Pretty hard to imagine how a faulty HSI would cause loss of control-- even in inadvertent IMC.... You don't fly IFR do you? :-)) An AI, or HSI usually fails slowly. It just slowly rolls over to one side or the other. If the pilot doesn't have a good scan technique he just rolls with it. I've flown that area and had the weather get really hazy just before dark. Still VMC, but enough to start relying on the gauges. I've also gotten caught down there when the visability went for good to nil in a very short time. It wasn't real problem, but if you aren't prepared it can scare you and getting disoriented is a strong likely hood.

Pretty hard to imagine how a faulty HSI would cause loss of
control-even in inadvertent IMC.... You don't fly IFR do you? :-)) An AI, or HSI usually fails slowly. It just slowly rolls over to one side or the other. If the pilot doesn't have a good scan technique he just rolls with it. Yes, but probably not as much as you. Agreed about the AI, disagree about the HSI. Seems to me there's a BIG difference in the implications and dangers between AI failing, which can cause loss of airplane ATTITUDE control, and and HSI or DG failing, which could cause some loss of NAVIGATIONAL awareness. If your Horizontal Situation Indicator gradually turns to an incorrect heading, do you think you might gradually, unknowingly, increase your bank angle trying to "follow" it? Or maybe the CDI going off-scale would induce you into a 60-degree bank trying to "catch it"? I think not. -- Cheers, John Clonts Temple, Texas N7NZ |

Losing a navigation instrument isn't a very good excuse to lose attitude control even in IMC. Matt |

Good judgment is something else Munson didn't have. Showing off flaps-up
touch-and-goes in a Citation at night wasn't the smartest thing. "jsmith" wrote in message ... Which we know as "Thurmond Munson Syndrom" kontiki wrote: Having lots of money can buy you almost anything... except experience. |
