If an aircraft has a fuel leak, which publication should be consulted?

In the event of a fuel leak, referring to the Manufacturer's Manual is the most appropriate action. This publication typically contains essential information regarding the aircraft's design, systems, and troubleshooting procedures specific to that aircraft model. It provides guidelines for handling various operational scenarios, including emergencies like fuel leaks.

The Manufacturer's Manual includes detailed procedures for identifying the source of the leak, assessing the severity, and implementing the necessary corrective actions to mitigate risks. It may also provide information on emergency procedures related to fuel systems and recommendations for maintaining safety.

While the Aircraft Maintenance Manual (AMM) is also a valuable resource, as it focuses on maintenance practices and detailed procedures for repairs, the Manufacturer's Manual is typically more directed toward operational guidance, making it the first point of reference in an emergency situation like a fuel leak.

The Pilot Operating Handbook (POH) is important for flight operations and performance data but does not usually contain extensive troubleshooting or emergency procedures related to fuel system issues. The FAA Regulations Handbook primarily outlines regulatory requirements and does not provide specific details about aircraft systems or emergency responses.
