What action should a mechanic take if issues are found and there is no MEL?

In situations where a mechanic discovers issues with an aircraft and no Minimum Equipment List (MEL) exists, the appropriate action is to deactivate and placard the aircraft. This approach ensures that the aircraft is rendered unairworthy until the identified discrepancies can be properly addressed. By deactivating the inoperative systems or components and placarding the affected areas, the mechanic communicates to all personnel that the aircraft should not be operated until repairs are completed, effectively preventing unsafe conditions.

This action aligns with safety regulations and policies in aviation maintenance, emphasizing the importance of thorough inspections and maintenance protocols. It protects the integrity of the aircraft and ensures compliance with regulatory standards regarding airworthiness. Proper placarding also serves as a clear visual warning to pilots and maintenance staff about the inoperative status of certain aircraft systems, which is crucial for flight safety.

The other choices typically involve actions that might not be suitable in the absence of an MEL. Immediate repairs may not be feasible in all circumstances, reporting to the FAA may not necessarily be the correct response unless there are significant safety violations, and scheduling a follow-up would delay addressing the aircraft’s airworthiness effectively. Thus, deactivating and placarding is the most responsible action to ensure safety until the aircraft can be returned to full
