Airworthiness Directive · Amendment 39-13389 · Airbus Model A300 B4-622R and A300 F4-622R Airplanes, and Model A310-324 and -325 Series Airplanes
Airbus Model A300 B4-622R and A300 F4-622R Airplanes, and Model A310-324 and -325 Series Airplanes
Model A300 B4-622R and A300 F4-622R airplanes, and Model A310-324 and -325 series airplanes, equipped with Pratt & Whitney PW4000 series engines; certificated in any category; except those on which Airbus Modification 12468 has been accomplished in production.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300 B4-622R and A300 F4-622R airplanes, and Model A310-324 and -325 series airplanes, that are equipped with Pratt & Whitney PW4000 series engines. This AD requires replacement of the existing flexible hose assembly that connects the oil pressure transmitter to the main oil circuit, with a new improved tube assembly. This action is necessary to prevent failure of the oil pressure indicator and low-oil-pressure warning in the event of an engine fire, which could result in an unannounced shutdown of the engine. 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.
