## Summary

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