Airworthiness Directive · Amendment 39-13641 · BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Series Airplanes
BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Series Airplanes
Model BAe 146 and Avro 146-RJ series airplanes, equipped with Pacific Scientific engine fire extinguisher bottles, and having BAE Systems (Operations) Limited Modification HCM01688A, and either HCM01582A or HCM01582B installed; certificated in any category;
This amendment adopts a new airworthiness directive (AD), applicable to certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes equipped with Pacific Scientific engine fire extinguisher bottles. This amendment would require a one- time inspection to detect discrepancies in the wiring installation of the engine fire extinguisher bottles, and related investigative/ corrective actions as necessary. This action is necessary to prevent the inability of the left-hand fire extinguisher on one or more engines to discharge, and consequent inability to control or suppress an engine fire. 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.
