Airworthiness Directive · Amendment 39-15643 · Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 Airplanes, and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 Airplanes, and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
This AD applies to all EMBRAER Model EMB-135ER, -135KE, -135KL, -135LR, and -135BJ airplanes; and all Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes; certificated in any category.
The FAA is superseding an existing airworthiness directive (AD), which applies to certain EMBRAER Model EMB-135 airplanes and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. That AD currently requires replacing the metallic tubes enclosing the vent and pilot valve wires in the left- and right-hand wing fuel tanks with non-conductive hoses. This new AD adds airplanes to the applicability of the existing AD. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent an ignition source inside the fuel tank that could ignite fuel vapor and cause a fuel tank explosion and loss of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For airplanes identified in the applicable service bulletins specified in paragraphs (f)(1) and (f)(2) of this AD: Within 5,000 flight hours or 48 months after July 19, 2007 (the effective date of AD 2007-12-17), whichever occurs first, replace the metallic tubes enclosing the vent and pilot valve wires in the left- and right-hand wing fuel tanks with new, improved, non-conductive hoses, in accordance with the Accomplishment Instructions of the service bulletins specified in paragraph (f)(1) or (f)(2) of this AD, as applicable.
(1) For Model EMB-135ER, -135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes: EMBRAER Service Bulletin 145-28-0023, Revision 07, dated February 7, 2007.
(2) For Model EMB-135BJ airplanes: EMBRAER Service Bulletin 145LEG-28-0018, Revision 01, dated April 20, 2005.
(g) For Model EMB-135ER, -135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes that are not identified in paragraph (f)(1) of this AD: Within 5,000 flight hours or 48 months after the effective date of this AD, whichever occurs first, replace the metallic tubes enclosing the vent and pilot valve wires in the left- and right-hand wing fuel tanks with new, improved, non-conductive hoses; in accordance with the Accomplishment Instructions of EMBRAER Service Bulletin 145-28-0023, Revision 11, dated December 4, 2007.
Actions accomplished before the effective date of this AD in accordance with the service information specified in Table 1 of this AD are considered acceptable for compliance with the corresponding actions of this AD.
