AD 2003-16-02 Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F Airplanes

Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F airplanes; as listed in Boeing Alert Service Bulletin (ASB) DC10-28A241, dated April 24, 2003; certificated in any category.

Required as indicated, unless accomplished previously. To prevent heated localized temperatures within the fuel boost/transfer pumps due to frictional heating, which could result in a potential source of ignition in a fuel tank and consequent fire or explosion, accomplish the following: Inspection/Records Review/Follow-on Actions (a) Within 90 days after the effective date of this AD: Do a general visual inspection of the fuel boost/transfer pumps to determine if Hydro-Aire part number (P/N) 60-847-1A is installed. Instead of inspecting the pumps, a review of the airplane maintenance records is acceptable if the P/N of the pumps can be positively determined from that review. Do the actions per the Work Instructions of Boeing Alert Service Bulletin DC10-28A241, dated April 24, 2003. (1) If the inspection and/or records verify that no pump having P/N 60-847-1A is installed, no further action is required by this paragraph. (2) If the inspection and/or records verify that a pump having P/N 60-847-1A is installed, do the applicable actions specified in paragraph (b) of this AD. Note 1: For the purposes of this AD, a general visual inspection is defined as: “A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to enhance visual access to all exposed surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.” (b) With the exception of fuel boost pumps having P/N 60-847-1A that are located in the aft position of the main tanks: Do the applicable actions specified in paragraph (b)(1) or (b)(2) of this AD, at the applicable times specified, per the Work Instructions of Boeing Alert Service Bulletin DC10-28A241, dated April 24, 2003. (1) If replacement pumps having either P/N 60-847-2 or P/N 60-847-3 are available, within 90 days after the effective date of this AD, replace the pumps per Option 1 of Condition 3 of the ASB. With the exception of paragraph (c) of this AD, this constitutes terminating action for the requirements of this AD. (2) If replacement pumps are not available, do the actions specified in paragraph (b)(2)(i), (b)(2)(ii), or (b)(2)(iii) of this AD within 90 days after the effective date of this AD. (i) Deactivate pumps having P/N 60-847-1A per the McDonnell Douglas DC-10 Minimum Equipment List (MEL) and replace the pump with a pump having P/N 60-847-2 or 60-847-3 within the time limitations specified in the MEL, per Option 2a. of Condition 3 of the ASB. (ii) Relocate the pumps per Option 2b. of Condition 3 of the ASB. Or, (iii) Insert Appendix A of the ASB into the Limitations Section of the Airplane Flight Manual. Note 2: Fuel boost pumps having P/N 60-847-1A that are located in the aft position of the main tanks are always covered with fuel during takeoff; therefore, operating the airplane per the operations limitations specified in Appendix A of Boeing Alert Service Bulletin DC10-28A241, dated April 24, 2003, is unnecessary. Parts Installation (c) As of the effective date of this AD, no person shall replace a fuel boost/transfer pump on any airplane with a fuel boost/transfer pump having Hydro-Aire P/N 60-847-1A, unless that pump is installed in the aft position of the main tanks. A fuel boost/transfer pump having Hydro-Aire P/N 60-847-1A that is removed for inspection per paragraph (a) of this AD may be reinstalled until paragraph (b) of this AD is complied with. Alternative Methods of Compliance (d) In accordance with 14 CFR 39.19, the Manager, Los Angeles Aircraft Certification Office, FAA, is authorized to approve alternative methods of compliance for this AD. Incorporation by Reference (e) Unless otherwise specified in this AD, the actions shall be done per Boeing Alert Service Bulletin DC10-28A241, dated April 24, 2003. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
