Which action should be performed if flaps retract after lifting lightly on them during a preflight check?

The appropriate action to take when flaps retract after lifting lightly on them during a preflight check is to cycle the flap handle and confirm operation. This procedure is critical because it allows the pilot to verify that the flap system is functioning correctly before flight. By cycling the flap handle, the pilot can ensure that the flaps extend and retract as intended, which provides an opportunity to identify any abnormalities in the flap operation during the preflight inspection.

Confirming the operation of the flaps involves testing the entire system under normal operating conditions. If the flaps do not respond as expected after cycling the handle, this indicates a potential issue that requires further investigation. Ensuring the proper functioning of all flight control surfaces, including flaps, is imperative for the safety of the flight.

Other options, while relevant to maintenance or reporting issues, do not directly address the immediate need to verify and check the flap operation during preflight procedures. Taking proactive steps to cycle the flap handle gives the pilot a better understanding of the aircraft's condition before taking off.
