Airworthiness Directive · Amendment 39-10577 · British Aerospace Model H.P. 137 Jetstream Mk. 1, Jetstream Model 3101, Jetstream Model 3201, and Jetstream 200 Series Airplanes
British Aerospace Model H.P. 137 Jetstream Mk. 1, Jetstream Model 3101, Jetstream Model 3201, and Jetstream 200 Series Airplanes
Superseded. A later AD replaced this one: AD 98-21-16. Comply with the one in force.
Model H.P. 137 Jetstream Mk. 1, Jetstream Model 3101, Jetstream Model 3201, and Jetstream 200 series airplanes, all serial numbers, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that applies to certain British Aerospace (BAe) Model H.P. 137 Jetstream Mk. 1, Jetstream Model 3101, Jetstream Model 3201, and Jetstream 200 series airplanes. This AD requires replacing the windshield wiper arm attachment bolts and windshield wiper arm on all of the affected airplanes; and measuring the material thickness of the upper and lower toggle attachment brackets on the nose landing gear of the affected airplanes, and replacing the toggle attachment bracket lugs. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified by this AD are intended to prevent the windshield wiper arm from corroding, detaching from the airplane during flight, and penetrating the fuselage, which could result in possible injury to the pilot and passengers; and to prevent collapse of the nose landing gear caused by design deficiency, which could result in loss of control of the airplane during landing operations.
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.
