McDonnell Douglas Model DC-10-10 and DC-10-10F Airplanes, Model DC-10-15 Airplanes, Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) Airplanes, Model DC-10-40 and DC-10-40F Airplanes, Model MD-10-10F and MD-10-30F Airplanes, and Model MD-11 and MD-11F Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) McDonnell Douglas Model DC-10-10 and DC-10-10F airplanes, Model DC-10-15 airplanes, Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) airplanes, Model DC-10-40 and DC-10-40F airplanes, and Model MD-10-10F and MD-10-30F airplanes; as identified in Boeing Alert Service Bulletin DC10-28A254, Revision 1, dated September 12, 2007.
(2) McDonnell Douglas Model MD-11 and MD-11F airplanes, as identified in Boeing Alert Service Bulletin MD11-28A134, Revision 1, dated September 6, 2007.
The FAA is adopting a new airworthiness directive (AD) for certain transport category airplanes identified above. This AD requires modifying the fuel boost pumps. This AD results from a fuel boost pump found with blown thermal fuses and a fractured thrust washer. We are issuing this AD to prevent failure of the fuel boost pumps, which could lead to the potential of ignition sources inside fuel tanks. This condition, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Comply with this AD within the compliance times specified, unless already done.
The term “service bulletin,” as used in this AD, means the following service bulletins, as applicable:
(1) For the airplanes identified in paragraph (c)(1) of this AD, Boeing Alert Service Bulletin DC10-28A254, Revision 1, dated September 12, 2007.
(2) For the airplanes identified in paragraph (c)(2) of this AD, Boeing Alert Service Bulletin MD11-28A134, Revision 1, dated September 6, 2007.
Note 1: Boeing Alert Service Bulletin DC10-28A254, Revision 1, dated September 12, 2007; and Boeing Alert Service Bulletin MD11-28A134, Revision 1, dated September 6, 2007; refer to Crane Hydro-Aire Service Bulletin 60-847-28-3, Revision 1, dated July 2, 2007, as an additional source of service information for accomplishing the modification in paragraph (g) of this AD.
At the applicable compliance time specified in paragraph (g)(1) or (g)(2) of this AD, modify the fuel boost pumps having part numbers 60-847-1A, -2, or -3, in accordance with the Accomplishment Instructions of the applicable service bulletin.
(1) For fuel boost pumps identified as Configuration 1 or 2 in Table 1 of paragraph 1.E. of the applicable service bulletin, do the modification within 120 months after the effective date of this AD.
(2) For fuel boost pumps identified as Configuration 3 in Table 1 of paragraph 1.E. of the applicable service bulletin, do the modification within 72 months after the effective date 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.
