Airworthiness Directive · Amendment 39-21935 · Gust lock/damper system
British Aerospace (Operations) Limited and British Aerospace Regional Aircraft Airplanes
This AD applies to British Aerospace (Operations) Limited and British Aerospace Regional Aircraft Model Jetstream Series 200, Jetstream Model 3101, and Jetstream Model 3201 airplanes, serial numbers 1 through 927 and 929 through 936 inclusive, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain British Aerospace (Operations) Limited and British Aerospace Regional Aircraft Model Jetstream Series 200, Jetstream Model 3101, and Jetstream Model 3201 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as a bent control rod within the gust lock system, which may enable both power levers to be pushed into the flight range with the gust lock lever fully engaged. This AD requires replacing the push rod assembly with a modified push rod assembly. The FAA is issuing this AD to address the unsafe condition on these products.
Within 2 years after the effective date of this AD, replace push rod assembly part number (P/N) 137201E419 with push rod assembly P/N 137201E429 by following the Accomplishment Instructions, sections 2.A. through 2.C. in Jetstream Series 3100/3200 Service Bulletin 27-JM 5350, Revision 1, dated May 6, 1994.
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.
