What does 14 CFR 121.629(c) require from the flightcrew regarding pretakeoff checks within the holdover time?

• A. Only the pilot needs to perform checks
• B. Check of the aircraft's wings for frozen contamination by the flightcrew only
• C. A team of ground personnel must perform the checks
• D. Checks can be skipped if no precipitation is present

Answer: (B)

The requirement outlined in 14 CFR 121.629(c) mandates that the flightcrew must conduct a thorough check of the aircraft's critical surfaces, specifically focusing on the wings and other areas for any signs of frozen contamination. This step is crucial because frozen contamination can significantly affect an aircraft's aerodynamics, performance, and safety during takeoff. By requiring the flightcrew to perform this check themselves, the regulation emphasizes the importance of direct accountability in ensuring that the aircraft is safe and ready for flight. The flightcrew's hands-on inspection allows them to assess the aircraft's condition accurately and determine whether de-icing or anti-icing procedures need to be applied before departure. This regulatory requirement is designed to enhance safety, particularly in winter operations where frozen contaminants are more prevalent. It reinforces that the responsibility for this critical check lies with the flightcrew, who are trained to understand the implications of contamination and the necessary actions to take to ensure safe flight operations.
