Airworthiness Directives; British Aerospace (Operations) Limited and British Aerospace Regional Aircraft Airplanes

FAA / Federal Register · 2023-15917

The FAA proposes to supersede Airworthiness Directive (AD) 2017-19-22, which applies to British Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream Model 3201 airplanes. AD 2017-19-22 requires incorporating BAE Systems' Corrosion Prevention and Control program into the Airworthiness Limitations Section (ALS) of the existing instructions for continued airworthiness (ICA) for your airplane, which adds new and more restrictive inspections for corrosion that include inspecting the door hinges/supporting structure and attachment bolts for the main spar joint and engine support, and the rudder hinge location on the vertical stabilizer, and applicable corrective actions. Since the FAA issued AD 2017-19-22, the Civil Aviation Authority (CAA) of the United Kingdom superseded the mandatory continuing airworthiness information (MCAI) issued by the European Aviation Safety Agency (EASA) to correct an unsafe condition on these products. This proposed AD would require revising the ALS of the existing ICA for your airplane. The FAA is proposing this AD to address the unsafe condition on these products.
