Narrative:

I was assigned to work aircraft X for a discrepancy of 'FMC faults' (flight management computer fault) that was called in on the radio by the flight crew. When I arrived at the aircraft; I was informed that the flight crew had reset the system twice and it was okay. This is not the first time this type of action has happened where the flight crews are resetting circuit breakers and aircraft systems and are not documenting the maintenance performed on aircraft as required per the fars (code of federal regulations). They are also are not accomplishing the required ops (operational) test; system test or lmp test per the maintenance manual; troubleshooting manual; general procedures manual.flight crew and moc (maintenance control) are not following maintenance procedures. Moc are instructing flight crews to reset circuit breakers at the gate; when it is not their function and they are not qualified to perform specific maintenance task such as lmp test on lmp components and systems. They are also not documenting these discrepancies or the actions taken when they reset circuit breakers and are not documenting the maintenance references required. The flight crews are being instructed to contact moc by aircraft maintenance supervisors and when the flight crew calls moc; moc is instructing them to reset breakers. At times; the flight crew is not aware that the item is an lmp component or system; which requires the work to be performed by a qualified lmp technician and requires an lmp test. Which the flight crew can't perform because they're not qualified and if done by unqualified personnel the aircraft lmp status must be downgrade per the gpm (general process manual).flight crew needs to enter all discrepancies in the logbook when they call aircraft maintenance for assistance and inform them of a discrepancy on the aircraft. Moc needs to stop instructing flight crews to reset circuit breakers at the gate and interrupting critical aircraft systems without allowing qualified aircraft technicians to address the discrepancy and accomplish all required test and procedures required per maintenance manual and gpm.
