How should the fuel system be drained on the Beechcraft Travel Air BE-95?

Draining the fuel system on the Beechcraft Travel Air BE-95 should be done using the drain valves located at the bottom of the fuel tanks. This method is the most effective and safe means of removing fuel. The drain valves are specifically designed for this purpose, allowing for controlled and complete draining of fuel, which helps in preventing contamination and ensuring that any water or sediment in the tanks is removed. This approach is essential for maintaining the system's integrity and ensuring optimal performance, as it allows for proper inspection and management of the fuel system.

Utilizing a siphon or a hand pump may introduce the risk of fuel spillage and contamination, while running the engine until empty could result in fuel starvation and damage to the engine components. Therefore, the use of drain valves is the preferred and safest method for draining the fuel system on the BE-95.
