Background

    Note 3 attachment to Table 2, Fuel Resistance and Extreme 
Temperature Test Schedule, is located in Appendix 1 of TSO-C76a, only 
appears in the ``a'' version. A subsequent review of the ``a'' revision 
of TSO-C76 determined that the revised temperature values contained in 
Note 3 were arbitrary and provides no technical value to the 
qualification of fuel drain valves, nor will the testing to those 
temperature values provide an increase in the operational safety of the 
fuel drain valve. Therefore, we are taking this opportunity to cancel 
TSO-C76a.

    Issued in Washington, DC, on July 30, 2009.
Susan J.M. Cabler,
Assistant Manager, Aircraft Engineering Division, Aircraft 
Certification Service.
