Boeing Model 747-200B, 747-300, 747-400, and 747-400D Series Airplanes
This AD applies to the Boeing airplanes, certificated in any category, specified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD.
(1) Model 747-200B and 747-300 series airplanes identified in Boeing Special Attention Service Bulletin 747-53-2497, dated November 4, 2004.
(2) Model 747-200B and 747-300 series airplanes on which Boeing Service Bulletins 747-25-2716, 747-25-2724, and 747-25-2784 have been done.
(3) Model 747-400 and 747-400D series airplanes identified in Boeing Special Attention Service Bulletin 747-53-2481, dated October 24, 2002.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-200B, 747-300, 747-400, and 747-400D series airplanes. This AD requires modifying the lateral shear beam for the Door 5 crew rest and, for certain airplanes, replacing Zone E tie rods and modifying the Zone E stowbin ladder. This AD results from a report indicating that the lateral shear beam for the Door 5 crew rest does not meet the 9G forward loading requirement. We are issuing this AD to prevent the structural support for the Door 5 crew rest and Zone E stowbins from failing, which could result in the crew rest or stowbins falling during an emergency and consequent injury to crew and passengers.
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 60 months after the effective date of this AD, modify the lateral shear beam for the Door 5 crew rest by accomplishing all of the actions specified in the Accomplishment Instructions of Boeing Special Attention Service Bulletin 747-53-2497, dated November 4, 2004.
Within 60 months after the effective date of this AD, modify the lateral shear beam for the Door 5 crew rest, replace the Zone E tie rods, and modify the Zone E stowbin ladder, by accomplishing all of the actions specified in the Accomplishment Instructions of Boeing Special Attention Service Bulletin 747-53-2481, dated October 24, 2002.
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.
