Airworthiness Directive coverage
FAA / EASA public regulatory data
- FAAAD 2021-16-06effective Sep 27, 2021ProhibitionNamed as replacement part
The FAA is superseding Airworthiness Directive (AD) 2020-19-11 for certain Leonardo S.p.a. Model A119 and AW119 MKII helicopters. AD 2020-19-11 required repetitive borescope inspections of the 90-degree tail rotor gearbox (TGB) and depending on the inspection results, removing the TGB from service. This AD was prompted by the determination that additional parts may be susceptible to the unsafe condition. This AD retains the inspection requirements of AD 2020-19-11, and revises the compliance time and applicability. The FAA is issuing this AD to address the unsafe condition on these products.

Directives citing this part number in the FAA / EASA regulatory corpus we have processed — not a complete historical AD list. An AD is a compliance requirement that drives scheduled work (inspections, replacements, modifications) on the fleets that carry the part; a directive naming this PN as the replacement part is install demand, not an action against it — and none of this is a prediction that the part will fail.
