How much corrosion is too much?
I searched the archives, and found discussion on problems that corrosion has
caused, but haven't found any dealing with the role of corrosion in the sale of an airplane. I know most of you steadfastly maintain that ANY corrosion is bad. But, in reality, how many of you have purchased anyway, knowing that some corrosion existed? I'm not talking about just the thin white dusting type corrosion that is almost common in all aircraft. I'm talking stuff where you can see "piles" 1/32th of an inch or so of powder fairly well distributed. I'm not talking exfoliation type stuff. See some pics below. The first is an inspection cover. The 2nd is the interior of the tail inspection area. With mirrors, you can see the "piles" on the lower surface of the horizontal stab skin. http://f2.pg.photos.yahoo.com/ph/cor...bum?.dir=/4be0 So, if you're in a dry area, and if you start treating with Corrosion-X or other, would you do it? The A&P says that it could last another 15-20 years. BUT... I have to look at resale down the line. Thanks for any opinions; Carl |

OK; think I've got it now. Have never posted to Yahoo, so I hadn't shared
them out. I *think* I've set it correctly now.

I'd have a really close look at the outside surfaces, opposite the corroded areas, and look for tiny blisters. Poke these with a small, sharp tool like an awl, and if it goes through easily, the metal is shot. BTDT. There might be much worse corrosion in the riveted joints where you can't see so well. Such areas tend to trap moisture, and electrical current through these areas can accelerate corrosion. Look for animal nests inside pest-accessible areas like the wings and elevators (it is a 172, right?). They get in through lightening holes (inboard ends of elevators and between aileron and wing) and do terrific damage with their wastes. Dan |

No outside blisters whatsoever (I thought the same thing). Yes, it's a 172.

Looks like a bunch. Scotchbrite and treat. Replace it later in your
career!
