BAE Systems (Operations) Limited Model BAe 146-200A Series Airplanes
Model BAe 146-200A series airplanes, as listed in BAE Systems (Operations) Limited Modification Service Bulletin SB.27-109-00503C, Revision 3, dated March 19, 2001; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain BAE Systems (Operations) Limited Model BAe 146- 200A series airplanes, that requires replacement of the signal summing units (SSUs) for the stall identification system with new, improved parts. The actions specified by this AD are intended to prevent stall identification and stall warning signals from occurring at the same time, leading the flight crew to take action based on erroneous information, 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.
