Airworthiness Directive · Amendment 39-14937 · McDonnell Douglas Model DC-8-62, DC-8-63, DC-8-62F, and DC-8-63F Airplanes
McDonnell Douglas Model DC-8-62, DC-8-63, DC-8-62F, and DC-8-63F Airplanes
This AD applies to McDonnell Douglas Model DC-8-62 and DC-8-63 airplanes and Model DC-8-62F and DC-8-63F airplanes, certificated in any category; as identified in McDonnell Douglas DC-8 Service Bulletin 78-95, Revision 2, dated March 10, 1971.
The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-8-62, DC-8-63, DC-8-62F, and DC-8- 63F airplanes. This AD requires revising the wiring for the engine thrust brake circuit and indicating circuit and other specified actions, or rerouting the wiring at plug P1-1762A on the electrical power center generator control panel, as necessary. This AD results from the determination that the thrust reverser systems on these airplanes do not adequately preclude inadvertent deployment of the thrust reversers. We are issuing this AD to prevent inadvertent deployment of the thrust reversers during takeoff or landing, which could result in loss of control of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 27 months after the effective date of this AD, do the applicable action specified in paragraph (f)(1) or (f)(2) of this AD, by accomplishing all of the applicable actions specified in the Accomplishment Instructions of McDonnell Douglas DC-8 Service Bulletin 78-95, Revision 2, dated March 10, 1971; or Revision 1, dated December 29, 1970.
(1) Revise the wiring for the engine thrust brake circuit and indicating circuit, and do all other specified actions before further flight after revising the wiring.
(2) Reroute the wiring at plug P1-1762A on the electrical power center generator control panel.
