hi,
Thank you for your posts.

I think safety harness is mentioned in the AMM (737-200), I don't know if it is used for trimming purpose or high power checks, may be not used on high bypass engines?
When performing leak check above idle, are the fan cowls open or closed (let's say there is a leak in the fan case area)? I am asking this because when engine is above idle, the suction or injestion area is increased over the fan case, and with the cowls open this may cause damage to the fan case and also to the engine through FOD (items or part of items may be tear off from the fan case and sucked into engine).
I read that some engines can be operated at 70%0 N1 to perform part-power leak check, how this is performed? (fan cowls open or close, if open the AMT must be near engine.....?)
I guess it is not eazy to find a leakage with cowls closed (thrust reverser and fan cowls) and engine running at idle or above.
Feedback appreciated. Thank you.
Best regards.
