After landing, if you suspect a fault developed in flight, what is the recommended action?

• A. Immediately turn off the aircraft.
• B. Coordinate with maintenance after landing.
• C. Ignore and continue.
• D. File a complaint.

Answer: (B)

When you suspect a fault developed in flight, the priority is to get qualified people involved and document what happened. After landing, you should coordinate with maintenance and report the suspected fault, making sure it’s entered in the aircraft’s technical log with as much detail as possible (which system, what symptoms, when it occurred, any related cockpit messages). This kicks off the proper inspection, fault isolation, and any MEL (Minimum Equipment List) procedures, so the aircraft can be handled safely and accurately.

Documenting and handing the issue to maintenance preserves evidence and ensures the fault won’t be overlooked or misdiagnosed on a later flight. It’s about safety and proper disposition: you don’t try to fix it yourself or ignore it, and you don’t just file a general complaint. Coordinating with maintenance after landing is the appropriate, systematic path to resolve the issue.
