Airworthiness Directive · Amendment 39-13664 · BAE Systems (Operations) Limited Model BAe 146 Series Airplanes
BAE Systems (Operations) Limited Model BAe 146 Series Airplanes
All Model BAe 146 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to all BAE Systems (Operations) Limited Model BAe 146 series airplanes, that requires repetitive detailed inspections of the inside of each air conditioning sound-attenuating duct, and corrective actions as necessary. This action is necessary to prevent impairment of the operational skills and abilities of the flightcrew caused by the inhalation of agents released from oil or oil breakdown products, which could result in reduced controllability of the airplane. 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.
