Notice of proposed rulemaking (NPRM).

We propose to supersede Airworthiness Directive (AD) 2013-24- 13, which applies to certain The Boeing Company Model 737-100, -200, - 200C, -300, -400, -500, -600, -700, -700C, -800, and -900 series airplanes. AD 2013-24-13 currently requires 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 airplanes. AD 2013-24-13 also requires inspecting, changing, or repairing the seat track link assembly for certain other airplanes. Since we issued AD 2013-24-13, a paragraph reference was found to be mis-identified. This proposed AD would correct this paragraph reference. We are proposing this AD to prevent seat detachment in an emergency landing, which could cause injury to occupants of the passenger compartment and affect emergency egress.
