Airworthiness Directive · Amendment 39-13189 · Embraer S.A. Airplanes
Embraer S.A. Airplanes
This AD applies to Embraer S.A. EMB-135BJ (Legacy 600), EMB-135ER, EMB-135KE, EMB-135KL, EMB-135LR, EMB-145, EMB-145ER, EMB-145LR, EMB-145MR, EMB-145XR.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-135 and -145 series airplanes, that requires replacing the four Gamah clamp/sleeve joints on an engine bleed air duct with new threaded coupling assemblies. For certain airplanes, this AD also requires replacing the two supports for the engine bleed air duct with two new supports. The actions specified by this AD are intended to prevent hot air leaks from the bleed air duct due to disconnection of the duct joint, which could result in heat damage to components near the duct, and consequent increased risk of fire in the rear baggage compartment. This action is intended to address the identified unsafe condition.
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.
