Have you read an MEL, it's not always black and white and is open to interpretation?
Hi spanner,
I appreciate always yr good and wise posts, but here I disagree with U.
We have the power to say no , I did it a couple of times, also due to inadequate documentation. This is called good workmanship, for that we get our money.
In my job in MCC in a so called "*****" airline I see a lot of bulls..t done by qualified engineers. Trying to bring the plane out instead of safe work.
Remember: we keep them flying........SAFE
seemed strange to me, so I did something the FIM didn't say and it cured it, saved a delay and the cost of a main battery. Was I right to do that, it was outside the book?
Original Boing FIM:
Fault Isolation Task Features
A. General
(1) The FIM is a tool to help you operate the airplane economically. The procedures in the FIM help you to
quickly isolate the cause of each airplane fault.
(2) To isolate the cause of a fault, you can also use your knowledge from:
(a) Your past experience with airplane faults
(b) The conditions under which the fault occurred
(c) The history of faults on your airplane or your fleet.
(3) It is not a requirement to do the steps in the FIM procedure in the order shown. But if you do not plan to
follow the FIM procedure exactly, make sure that you read it before you start to isolate the fault. Some FIM
procedures start with important steps that have an effect on other steps later in the procedure.
Step 2a) So go ahead with yr good workmannship, You are allowed to do it , so long U know what U do.
Good luck everyone.....
