The FAA proposes to supersede Airworthiness Directive (AD) 2020-19-11 for certain Leonardo S.p.a. Model A119 and AW119 MKII helicopters. AD 2020-19-11 requires repetitive borescope inspections of the 90-degree tail rotor gearbox (TGB) and depending on the inspection results, removing the TGB from service. Since the FAA issued AD 2020- 19-11, it was determined that additional parts may be susceptible to the unsafe condition. This proposed AD would retain the inspection requirements of AD 2020-19-11, and revise the compliance time and applicability. The FAA is proposing this AD to address the unsafe condition on these products.
