Airworthiness Directive · Amendment 39-14941 · 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 all EMBRAER Model EMB-135BJ, -135ER, -135KE, -135KL, and -135LR airplanes; and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all EMBRAER airplanes as described previously. This AD requires inspecting to determine the part number of the left- and right-hand windshield temperature controllers. For airplanes equipped with certain windshield temperature controllers, this AD also requires replacing the attaching hardware of the power cable terminals of the windshield temperature controllers with new, improved attaching hardware; inspecting the power cable terminals for signs of melting or damage to the terminals, cable insulation, or plastic crimping ring; and performing corrective actions if necessary. This AD results from reports of smoke on the flight deck caused by damage from poor electrical contact due to loosening of the attaching hardware of the power cables of certain windshield temperature controllers. We are issuing this AD to prevent overheating of the power cable terminals of the windshield temperature controllers, which could result in smoke on the flight deck.
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 after the effective date of this AD, inspect to determine the part number of the left- and right-hand windshield temperature controllers. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the subject controller can be conclusively determined from that review. If any windshield temperature controller is found to have a part number other than Goodrich P/N 3801D2(), no further action is required by this AD for that controller.
Before further flight after performing the inspection required by paragraph (f) of this AD, for all windshield temperature controllers having Goodrich P/N 3801D2() or any controller for which the part number cannot be conclusively determined: Replace the attaching hardware of the power cable terminals of the controllers with new, improved attaching hardware having new part numbers. Concurrently, perform a detailed inspection for signs of melting or damage of the plastic crimping ring, cable insulation, or terminals of the power cables, and, before further flight, perform applicable corrective actions. Perform all the actions in accordance with the Accomplishment Instructions of EMBRAER Service Bulletin 145-30-0043, Revision 02, dated May 25, 2006; or EMBRAER Service Bulletin 145LEG-30-0013, dated June 28, 2005; as applicable.
Actions accomplished before the effective date of this AD in accordance with EMBRAER Service Bulletin 145-30-0043, dated June 28, 2005; or Revision 01, dated April 7, 2006; are considered acceptable for compliance with the applicable corresponding actions required by 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.
