Yes it was a C model..


The reason this is so perplexing to me is that it occurred during the 3rd engine start of the day. It happened almost immediately after the started was engaged. Very little vibration here. The loop test passed after the fact, while the amp test failed. So obviously the problem, weather it was real or false, was within the amplifier. Replacing the loop corrected the problem.
 
I understand the problem is corrected, but how did replacing the loop do anything for a bad amplifier? Did I miss something?
 
Good question.

I don't know that the amplifier was "bad".. I just know that the amp test failed after the T-handle lit.

I guess it's possible that

a) the process of replacing the loop disturbed something that affected the amp's ability to pass a test

b) the amp test failure was an anomoly

c) you really did have a bad loop, but testing didn't show it as bad

This is a good example of the brain teasers I dealt with every day before I started flying. I think I enjoy the flying more.
