## Summary

The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain EMBRAER Model EMB-145XR airplanes. The original NPRM would have required replacement of certain segments of the passenger seat tracks with new, improved seat tracks. The original NPRM resulted from instances where the shear plungers of the passenger seat legs were not adequately fastened. This action revises the original NPRM by requiring new service information. We are proposing this supplemental NPRM to prevent inadequate fastening of the seat leg shear plungers, which could result in failure of the passenger seat tracks during emergency landing conditions and consequent injury to passengers.
