Understanding Aircraft Corrosion
I am in the process of purchasing a share in an aeroplane. The aircraft is 28yrs old and has been parked outside most of its life.
The pre-buy inspection has thrown-up ~6 areas of corrosion. Some of it regarded as "exfoliation" corrosion. Non of the areas are particularly big, but I am told that exfolition is the worst type and starts within the metal and works out.
So I am concerned, naturally.
Should I give this aircraft a wide berth?
One area of corrosion is, for example, one of the wing attachment bolts which is displaying a patch of corrosion on the surface.
I got the impression from the engineer that the presence of any exfolition is a deal-breaker?
Opinions greatly received.
