The Federal Aviation Administration's Airworthiness Directive 2020-22-18 addresses all Rolls-Royce Corporation AE 2100A, AE 2100D2, AE 2100D2A, and AE 2100P turboprop engines. This directive responds to a fatigue crack issue found in the propeller gearbox shaft and carrier assembly that caused high vibration during manufacturer testing. It mandates usage hour assignment and replacement of these assemblies before exceeding newly established life limits to ensure continued airworthiness.
