Boeing Model 747-100, 747-100B, 747-200B, 747-300, 747-400, 747-400D, 747SR, and 747SP Series Airplanes
This AD applies to certain Boeing Model 747-100, 747-100B, 747-200B, 747-300, 747SR, and 747SP series airplanes, as identified in Boeing Alert Service Bulletin 747-25A3287, Revision 2, dated September 4, 2003; and Model 747-400 and 747-400D series airplanes, as identified in Boeing Service Bulletin 747-25A3187, Revision 2, dated January 27, 2000; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-200B, 747-300, 747-400, 747-400D, 747SR, and 747SP series airplanes. This AD requires replacing or modifying the control panels for the galley cart lift and modifying related electrical cable assemblies, as applicable. This AD is prompted by reports of injuries to catering personnel and flight attendants who were loading or unloading galley carts on one deck when, due to a disabled or malfunctioning safety interlock door switch, the galley cart lift unexpectedly moved when it was activated from the control panel on the other deck. We are issuing this AD to ensure that the galley cart lift can be sent only from the deck on which it is in use, which will prevent unexpected movement of the cart lift that could result in possible injury to catering personnel or flight attendants.
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 18 months after the effective date of this AD, accomplish the actions required by paragraph (f)(1) or (f)(2) of this AD, as applicable.
(1) For Model 747-400 and 747-400D series airplanes: Replace the main and upper deck control panels for the galley cart lift with new or modified control panels by doing all the actions specified in Boeing Service Bulletin 747-25A3187, Revision 2, dated January 27, 2000.
(2) For Model 747-100, 747-100B, 747-200B, 747-300, 747SR, and 747SP series airplanes: Modify the main and upper deck control panels and related cable assemblies for the galley cart lift by doing all the actions specified in Boeing Alert Service Bulletin 747-25A3287, Revision 2, dated September 4, 2003.
Actions accomplished before the effective date of this AD in accordance with Boeing Alert Service Bulletin 747-25A3287, dated October 25, 2001, or Revision 1, dated April 25, 2002; or in accordance with Boeing Service Bulletin 747-25A3187, dated April 29, 1999, or Revision 1, dated September 23, 1999; are considered acceptable for compliance with the corresponding actions specified in paragraph (f) of this AD.
