Who may conduct the pre takeoff contamination check?

• A. PIC or designated person
• B. Ground crew
• C. Maintenance supervisor
• D. Any crew member

Answer: (A)

The key idea is who is authorized to verify that the aircraft is free of contamination before takeoff. In this procedure, the pilot in command has the ultimate responsibility for flight safety, but they may designate another qualified person to perform the pre-takeoff contamination check. That designated person must be trained and authorized by the operator to conduct the check. This ensures the person performing the inspection is competent to identify contamination on critical surfaces and to confirm that deicing/anti-icing has been applied correctly.

Ground crew or a maintenance supervisor aren’t authorized to perform this specific preflight verification as part of the takeoff decision, and “any crew member” would not guarantee the required training and authorization. The PIC or a designated, trained individual is the proper channel to perform the check.
