ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 83-18-02 McDONNELL DOUGLAS: Amendment 39-4718. Applies to CFM-56 powered McDonnell Douglas Model DC-8-70 series airplanes, with P/N 9984M90G20 fuel injectors installed on one or more engines, certificated in all categories. Compliance required as indicated, unless previously accomplished: A. To prevent possible engine flameouts while using JP4 or Jet B fuel accomplish the following within seven calendar days after the effective date of this AD: 1. Revise the limitations section of the FAA approved Airplane Flight Manual (AFM) to read: "Aircraft being operated with any amount of JP4 or Jet B fuel and equipped with one or more engines incorporating General Electric P/N 9984M90G20 injectors will require that the ignition override switch be placed in the ALL ENGINES position, on one or both systems, prior to and during descent through landing." 2. Install a placard in the cockpit, in clear view of the pilots, which reads: "With any amount of JP4 or Jet B fuel - Use ignition override prior to and during descent through landing." B. A copy of this AD inserted in the FAA approved Airplane Flight Manual is considered as an acceptable means of compliance with the required AFM revisions. C. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD. D. Alternate means of compliance which provide an equivalent level of safety may be used when approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region. NOTE: Replacement of all P/N 9984M90G20 injectors on an aircraft with approved replacement injectors, removes that aircraft from the applicability of this AD, and permits removal at the AFM revision and placard required by paragraph A., above. This amendment becomes effective September 8, 1983. FOOTER:
