Background

This TSO is being re-issued in its entirety. We have cancelled TSO-C76a because the specific requirements that make up the minimum performance standard necessary to have the Fuel Drain Valves be marked as TOS approved, provided no technical value. Those requirements have resulted in manufacturers seeking TSO approval of their Fuel Drain Valves to experience difficulties in meeting the MPS. We have deemed the requirements to be arbitrary, resulting in our re-issuing of the original TSO-C76.

Issued in Washington, DC, on July 30, 2009.

Assistant Manager, Aircraft Engineering Division, Aircraft Certification Service.
