Airworthiness Directives; British Aerospace Regional Aircraft Airplanes

We are superseding Airworthiness Directive (AD) 2014-07-09 for British Aerospace Regional Aircraft Jetstream Series 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 describes the unsafe condition as both the need for newly added inspections for corrosion, which includes the door hinges/supporting structure and attachment bolts for the main spar joint and engine support, and inadequate existing instructions for inspection for corrosion for several areas including the rudder hinge location on the vertical stabilizer. We are issuing this AD to require actions to address the unsafe condition on these products.
