AD FAA-2011-0384

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-700 series airplanes. This AD was prompted by reports that the aft seat leg fittings span the station (STA) 521.45 "stay-out zone." This AD requires for certain airplanes, replacing the seat track pivot link assemblies, seat track sections, and floor panels. For certain airplanes, this AD also requires moving certain rows of passenger seats. For certain other airplanes, this AD also requires inspecting certain areas of the seat tracks for damage, and corrective actions if necessary. We are issuing this AD to prevent failure of the seat attachment structure and possible injury to passengers during an emergency landing.
