AD FAA-2014-0020

We are superseding an airworthiness directive (AD) 87-02-04 for British Aerospace (Operations) Limited Model HP.137 Jetstream MK.1, Jetstream Series 200, and Jetstream Series 3101 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracking of the forward main landing gear yoke pintle resulting from corrosion pits leading to stress corrosion. We are issuing this AD to require actions to address the unsafe condition on these products.
