When someone asks you to do anything that isn't covered by the MEL (or AMM) ask them to fax you a letter signed by the chief engineer and QA manager authorising you to deviate from the approved procedure with step by step instructions detailing exactly what they want you to do......
Yeah, I was going to make the same statement, just my experience especially with our current operator would never recieve this kind of relief. Loved your statement about "step by step instructions". I have refused to go with an E.A. as engineers constantly write them vague leaving ambiguous interpretation of the authority EG: refer back to an AMM that conflicts with the true condition. They have to conform as well to process standards but try to leave the liability on myself, no way my friend..
