Airworthiness Directive · Amendment 39-18095 · Fuselage
The Boeing Company Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) The Boeing Company Model 737-100, -200, -200C, -300,—400, and -500 series airplanes, as identified in Boeing Special Attention Service Bulletin 737-53-1260, Revision 1, dated May 23, 2013.
(2) The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes, as identified in Boeing Service Bulletin 737-53-1244, Revision 5, dated July 27, 2011.
We are superseding Airworthiness Directive (AD) 2013-24-13 for certain The Boeing Company Model 737-100, -200, -200C, -300, -400, -500, -600, -700, -700C, -800, and -900 series airplanes. AD 2013-24-13 required replacing the pivot link assembly for certain airplanes, replacing the seat track link assemblies or modifying the existing seat track link assembly for certain airplanes, or modifying the existing seat track link assembly fastener for certain other airplanes. AD 2013-24-13 also required inspecting, changing, or repairing the seat track link assembly for certain other airplanes. Since we issued AD 2013-24-13, a certain paragraph reference in that AD was found to be mis-identified; this AD corrects this paragraph reference. We are issuing this AD to prevent seat detachment in an emergency landing, which could cause injury to occupants of the passenger compartment and affect emergency egress.
