Main gear door issue

[billsheila]

A&P did some tests and he says actuators are all fine. He thinks it is the power pack "time delay valve" and related adjustments. One prelim test seems to indicate it may be the internal non-adjustable valve, but he wants to do some added tests and jack it. This is frustrating because this power pack was replaced with a rebuilt unit only 3 years ago. The (original) 40 some odd year pack was working fine, but with a cracked aluminum hydraulic line coming out of it, I decided to replace the pack when the line was being changed. Bill
