If Engineering has worked the defect then certified the aircraft as serviceable, responsibility to move switches to the ready for flight position lies with the next crew taking the aircraft. We will make switch selections required for our tests and should leave them in the normal position or where the Aircraft Maintenance Manual states. This may or may not be where the Ops manual requires them to be for flight which is why pre-flight checks are so important.
The only people that know where pilots want switches placed are pilots. We work to the AMM not a Flt Ops Manual.
