Who is responsible for signing an A sheet?

The responsibility for signing an A sheet falls to the Plane Captain, who confirms that the aircraft is safe for flight, and the aircrew, who are responsible for pilot readiness. The A sheet serves as a critical document indicating that the aircraft has undergone all necessary maintenance checks and is deemed operationally ready.

The Plane Captain conducts thorough pre-flight inspections, verifying that all systems are functioning correctly and that any discrepancies are addressed. The aircrew, on the other hand, confirms that they are prepared for the flight and that the aircraft meets all safety and operational standards. Their joint signature on the A sheet represents a final acknowledgment of the aircraft's airworthiness.

This collaborative responsibility emphasizes the importance of teamwork in ensuring flight safety. While the Safety Officer, Maintenance Chief, or Flight Operations Officer each have vital roles within the aviation environment, the specific act of signing the A sheet reflects the direct accountability of both the Plane Captain and the aircrew for the condition of the aircraft before it takes to the skies.
