Airworthiness Directive · Amendment 39-14717 · Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ, -135ER, -135KE, -135KL, and -135LR Airplanes; and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ, -135ER, -135KE, -135KL, and -135LR Airplanes; and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
This AD applies to EMBRAER Model EMB-135BJ, -135ER, -135KE, -135KL, and -135LR airplanes; and EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes; certificated in any category; as identified in EMBRAER Service Bulletin 145LEG-53-0015, Revision 02, dated May 19, 2005, or 145-53-0049, Revision 03, dated August 10, 2005.
The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-135 and -145 series airplanes. This AD requires determining the torque values of the screws that attach the seat tracks to the airplane, and corrective action if necessary. This AD results from a report of undertorqued screws. We are issuing 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.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 5,000 flight hours or 36 months after the effective date of this AD, whichever occurs first, determine the torque values of the applicable screws that attach the seat tracks to the airplane. Use the Accomplishment Instructions of EMBRAER Service Bulletin 145LEG-53-0015, Revision 02, dated May 19, 2005 (for Model EMB-135BJ airplanes), or Service Bulletin 145-53-0049, Revision 03, dated August 10, 2005 (for the remaining airplanes). For any screw that has a torque value outside the limits specified in the service bulletin: Before further flight, retorque the screw in accordance with the Accomplishment Instructions of the service bulletin. Although the service bulletins recommend applying torque seal to the heads of the screws, this AD does not require that action.
Actions accomplished according to the applicable service bulletin listed in Table 1 of this AD are considered acceptable for compliance with the corresponding actions specified in this AD.
