Airworthiness Directive · Amendment 39-13862 · Boeing Model 737-100, -200, -300, -400, and -500 Series Airplanes
Boeing Model 737-100, -200, -300, -400, and -500 Series Airplanes
Model 737-100, -200, -300, -400, and -500 series airplanes; certificated in any category; equipped with intercostal support structures at stringer 5R and having a number 2 galley weight of 996 pounds or more (including any attached equipment that imposes loads on the galley).
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 737 series airplanes, that currently requires modification of certain fuselage support structure for the number 2 galley. This amendment requires modification of the same support structure using new methods based on new calculations. This amendment also expands the applicability of the existing AD to include additional airplanes. The actions specified by this AD are intended to prevent the galley from shifting, which could limit access to the galley door during emergencies, and result in injury to passengers and flightcrew. This action is intended to address the identified unsafe condition.
To prevent the galley from shifting, which could limit access to the galley door during emergencies, and result in injury to passengers and flightcrew, accomplish the following:
(a) The term “service bulletin,” as used in this AD, means the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-53-1154, Revision 1, dated October 3, 2002.
(b) Except as provided by paragraph (c) or (d) of this AD, as applicable: Within 18 months after the effective date of this AD, modify the upper attachment support structure of galley 2 from body station 344 to 360 inclusive, between right stringers 3 and 7, in accordance with the service bulletin.
(c) For airplanes listed in paragraphs (c)(1) through (c)(3) of this AD: Within 18 months after the effective date of this AD, modify the upper attachment support structure of galley 2 from body station 344 to 360 inclusive, between right stringers 3 and 7. Do the modification in accordance with a method approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA; or in accordance with data meeting the type certification basis of the airplane approved by a Boeing Company Designated Engineering Representative (DER) who has been authorized by the Manager, Seattle ACO, to make such findings. For a modification method to be approved, the approval must specifically reference this AD.
(1) Airplanes listed as Group 1 in the service bulletin, on which the galley has an allowable operating weight of 996 pounds or more.
(2) Airplanes listed as Group 2 in the service bulletin, on which the modifications specified in the initial release of the service bulletin have been incorporated.
(3) Airplanes listed as Groups 3 through 9 in the service bulletin for which the service bulletin specifies to contact Boeing.
(d) Instead of accomplishing the modification required by paragraph (b) or (c) of this AD, as applicable: Within 18 months after the effective date of this AD, do the actions specified in paragraphs (d)(1), (d)(2), and (d)(3) of this AD, in accordance with a method approved by the Manager, Seattle ACO; or in accordance with data meeting the type certification basis of the airplane approved by a Boeing Company DER who has been authorized by the Manager, Seattle ACO, to make such findings.
(1) Reduce the total weight limit of the galley to a maximum capacity of 995 pounds or less.
(2) Re-placard to specify the maximum capacity limit for the galley.
(3) Re-placard to specify the load limit for individual compartments, as necessary, to ensure that the total of the individual compartment weights does not exceed the maximum capacity for the galley.
(e) In accordance with 14 CFR 39.19, the Manager, Seattle ACO, is authorized to approve alternative methods of compliance (AMOCs) for this AD.
(f) Unless otherwise specified in this AD, the actions shall be done in accordance with Boeing Special Attention Service Bulletin 737-53-1154, Revision 1, dated October 3, 2002. 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.
