Bae Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Series Airplanes
Superseded. A later AD replaced this one: AD 2004-18-07. Comply with the one in force.
Model BAe 146 and Avro 146-RJ series airplanes, certificated in any category, as listed in BAe Systems (Operations) Limited Inspection Service Bulletin ISB.21-148, Revision 1, dated February 6, 2001.
This amendment adopts a new airworthiness directive (AD), applicable to certain BAe Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes, that requires identifying the discharge valves and cabin pressure controllers, and replacing them with new parts if necessary. The actions specified by this AD are intended to prevent the installation of incorrect pressurization discharge valves and cabin pressure controllers, which could subject the airframe to excess stress and adversely affect the airframe fatigue life. 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.
