F. Put the Airplane Back to its Usual Condition"
CaptainSandL,
Apologies - I didnt know it was in the 737 Manual, but that is possibly the exception to the rule. This statement has possibly been amended into the 737 manual as a result of previous incidents?
As stated by Fargoo - Engineers may try and return the flight deck to its original condition but it is more often left in the state "at the end of work". I don't know of anyone that will try to reset switches at the end of work. However; What is the "Usual Condition"? That may vary from contract to contract.
