Airworthiness Directive · Amendment 39-11969 · McDonnell Douglas Model DC-10, Model MD-10, and Model MD-11 Series Airplanes
McDonnell Douglas Model DC-10, Model MD-10, and Model MD-11 Series Airplanes
All Model DC-10, Model MD-10, and Model MD-11 series airplanes; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to all McDonnell Douglas Model DC-10, Model MD-10, and Model MD-11 series airplanes. This action requires revising the Airplane Flight Manual (AFM) to ensure that the flight crew is advised of appropriate procedures for disabling certain fuel pump electrical circuits following failure of a fuel pump electrical connector. For certain airplanes, this action also requires revising the AFM to prohibit resetting of tripped fuel pump circuit breakers. This action is necessary to prevent continued arcing following a short circuit of the fuel pump electrical connector, which could damage the conduit that protects the power lead inside the fuel tank, and result in the creation of a potential ignition source in the fuel tank. This action is intended to address the identified unsafe condition.
To prevent continued arcing following a short circuit of the fuel pump electrical connector, which could damage the conduit that protects the power lead inside the fuel tank, and result in the creation of a potential ignition source in the fuel tank, accomplish the following:
(a) Within 14 days after the effective date of this AD, insert applicable Interim Operating Procedures regarding abnormal operations for fuel pump electrical connector failures into the Procedures Section of the FAA-approved AFM, in accordance with Boeing Flight Operations Bulletin DC-10-00-01A, MD-11-00-03A, and MD-10-00-02A, dated September 20, 2000.
(b) For Model DC-10 and Model MD-11 series airplanes: Within 14 days after the effective date of this AD, insert the following information into the “Fuel Management” paragraph of the Limitations Section of the FAA-approved AFM which may be accomplished by inserting a copy of this AD into the AFM.
“Do not reset any tripped fuel pump circuit breakers.”
Note 1: If the information in paragraph (b) of this AD is already in the “Fuel Management” paragraph of the Limitations Section of the AFM, no further action is required by paragraph (b) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
