Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model EMB-135 and -145 series airplanes. This proposed AD would require determining the torque values of the screws that attach the seat tracks to the airplane, and corrective action if necessary. This proposed AD is prompted by a report of undertorqued screws. We are proposing this AD 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.
