yr right,
I just stick to the facts, it is as easy as that.
One of the things is if they ( who is they, underwriters??)won't to release an engine on condition
Prove it, show us an excerpt from a policy.
I don't think you even understand that it is the Registered Operator who is ultimately legally responsible for the completion of maintenance and the continuing airworthiness of an aircraft, not a/the LAME.
There is no issue with the definition of "manufacturer's recommended time between overhaul", that is simple and plain English and is accepted by the courts.
A reasonably useful working policy in Australian aviation is:
"Believe nothing that you hear, and only half what you see"
Tootle pip!!
PS: Do you understand that is is legally possible for an aircraft to be "signed out" without the involvement of an AME/LAME anywhere in the process?
