Airworthiness Directives; British Aerospace Model HP.137 Jetstream Mk.1, Jetstream Series 200, Jetstream Series 3101, and Jetstream Model 3201 Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to all British Aerospace Model HP.137 Jetstream Mk.1, Jetstream Series 200, Jetstream Series 3101, and Jetstream Model 3201 airplanes. This AD requires you to repetitively inspect the horizontal and vertical stabilizer attachment fittings and associated hardware for corrosion and wear (damage). If damage is found, this AD also requires you to repair or replace the damaged parts. 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 detect and correct damage on the horizontal and vertical stabilizer attachment fittings and associated hardware, which could result in failure of the attachment fittings. Such failure could lead to flutter and subsequent structural failure of the empennage.
