Airworthiness Directives; Engine Alliance Turbofan Engines

FAA / Federal Register · 2019-27889

The FAA is adopting a new airworthiness directive (AD) for all Engine Alliance (EA) GP7270 and GP7277 model turbofan engines with a certain low-pressure compressor (LPC) 1st-stage fan blade installed. This AD requires an ultrasonic inspection of the affected LPC 1st-stage fan blades and replacement of any affected fan blades that fail the inspection. This AD was prompted by a report of an in-flight shutdown (IFSD) of an engine due to the fracture of multiple fan blades. The FAA is issuing this AD to address the unsafe condition on these products.
