Airworthiness Directive · Amendment 39-14179 · Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
This AD applies to all EMBRAER Model EMB-135 and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes, certificated in any category; as identified in EMBRAER Service Bulletin 145-26-0012, Revision 01, dated January 6, 2005; and EMBRAER Service Bulletin 145LEG-26-0003, Revision 01, dated January 6, 2005.
The FAA is adopting a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This AD requires inspecting to determine the part number of the left and right engine fire handles; and replacing the engine fire handles with engine fire handles having different part numbers if necessary. This AD is prompted by cases of the internal circuit of the engine fire handle failing. We are issuing this AD to prevent failure of the internal circuit of the engine fire handle that could disable the fuel shut-off valves and the discharge of the fire extinguishing agent, which, in the event of a fire, could result in the inability to extinguish a fire.
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 1,000 flight hours or 180 days after the effective date of this AD, whichever is first: Inspect to determine the part number (P/N) of the left and right engine fire handles, in accordance with the Accomplishment Instructions of EMBRAER Service Bulletin 145-26-0012, Revision 01, dated January 6, 2005 (for Model EMB-135 and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes, except for Model EMB-135BJ airplanes); or EMBRAER Service Bulletin 145LEG-26-0003, Revision 01, dated January 6, 2005 (for Model EMB-135BJ series airplanes); as applicable. Instead of inspecting the left and right engine fire handles, a review of airplane maintenance records is acceptable if the P/Ns of the left and right engine fire handles can be determined conclusively from that review. If left and right engine fire handles, P/Ns 1-7054-1 and 2-7054-1, respectively, are found installed on the airplane, then no further action is required by this paragraph. If any engine fire handle having P/N 1-7054-2 or 2-7054-2 is found installed on the airplane, before further flight, replace the engine fire handle with an engine fire handle having P/N 1-7054-1 or 2-7054-1, as applicable, in accordance with the service bulletin.
As of the effective date of this AD, no person may install left or right engine fire handles, P/Ns 1-7054-2 and 2-7054-2, on any airplane.
Actions done before the effective date of this AD in accordance with EMBRAER Service Bulletin 145-26-0012, dated October 6, 2004; or EMBRAER Service Bulletin 145LEG-26-0003, dated October 6, 2004; as applicable; are acceptable for compliance with the requirements of paragraph (f) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
