## Summary

The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain EMBRAER Model EMB-135 and -145 series airplanes. The original NPRM would have required determining the torque values of the screws that attach the seat tracks to the airplane, and corrective action if necessary. The original NPRM resulted from a report of undertorqued screws. This action revises the original NPRM by referring to revised service information and expanding the applicability. We are proposing this supplemental NPRM to prevent improper torque of those screws, which in the case of a hard landing or a high deceleration impact condition could result in damage to the seat and possible subsequent injury to the passenger.
