Sorry, not gonna buy that. So you are saying before purchasing the airplane you never, nor did your mechanic, open an inspection cover? You or your mechanic never removed a cowling?


You're grasping at straws.

You buy junk, you get to fly junk. Or fix it.

My point is that I just expected better.

Just received the Maintenance Manual revisions, Part #D2500-2TR9, which update the February 1973 current Maintenance Manual, Part #D2500-2-13.

Corrosion! They had the knowledge and technology to zinc chromate all internal surfaces...but out of gross negligence and profit motive the airframes insides are bare metal...a crime against aviation in my opinion.

It's not bare metal. Zinc chromate doesn't prevent corrosion; and in some cases, it makes inspection more difficult. Corrosion takes many forms. So does corrosion prevention. A manufacturer isn't negligent because the manufacturer doesn't spray chromate on surfaces.

What do you mean zinc chromate doesn't prevent corrosion? That's not what I was told in A&P school.

my 73p riems was full zinc coated from the factory. all the aircraft part were
made in cessna's factory and then shipped to france for assembly.
so if mine was coated in 73 why did they stop? were all p's coated or
just the one riems purchased as cessna went broke?

[hharney]

Not sure Rick but it could be protocol that Riems set up or the fact that parts were being shipped across the pond and there would not be a controlled environment before assembly.
