The airworthiness directive
64-12-04 GENERAL DYNAMICS: Amdt. 742 Part 507 Federal Register June 5, 1964. Applies to All Models 22, 22M, 30 and 30A Aircraft.
Compliance required within 1,500 hours' time in service after the effective date of this AD, unless already accomplished.
Inadvertent operation of the engine air turbine starter at continuous overspeeds has occurred in flight. This caused failure of the starter with resultant damage to surrounding nacelle structure and propulsion systems. To preclude starter failures of this nature, the following modifications and airplane flight manual procedures are required:
(a) Modify the Models 22, 22M, 30, and 30A starter operation warning systems to include a master warning light indication when the starter valve is in the open position in accordance with the following General Dynamics/Convair Service Bulletins or an FAA approved equivalent:
(1) General Dynamics/Convair Service Bulletin 880 S.B. No. 80-5 for the Model 22.
(2) General Dynamics/Convair Service Bulletin 880M S.B. No. 80-2 for the Model 22M.
(3) General Dynamics/Convair Service Bulletin 990 S.B. No. 80-3 for the Models 30 and 30A.
(b) As an alternative for Models 30 and 30A aircraft, relocate the existing starter operation warning lights from the flight engineer's panel assembly to the pilot's overhead control panel per General Dynamics/Convair Service Bulletin 990 S.B. No. 80-1.
(c) FAA engineering approval of equivalent methods of complying with (a) shall be processed through the FAA, Aircraft Engineering Division, Western Region.
(d) Revise the Emergency Procedures section of the appropriate FAA approved Airplane Flight Manual to incorporate the procedure for isolating a malfunctioning starter valve in flight as set forth in the following FAA approved General Dynamics/Convair Airplane Flight Manual revisions:
(1) Revision 73 to CS 59-061 dated December 17, 1963, for Model 22-2 and Revision 74 to CS 59-019 dated December 17, 1963, for the Model 22-1.
(2) Revision 34 to CS 61-008 dated December 17, 1963, for the Model 22M.
(3) Revision 32 to CS 61-048 dated December 17, 1963, for the Model 30.
(4) Revision 14 to CS 62-046 dated December 17, 1963, for the Model 30A.
This directive effective July 6, 1964.
