Airworthiness Directives; Leonardo S.p.a Helicopters
FAA proposes to supersede AD 2021-12-10 for certain Leonardo Model AB139 and AW139 helicopters, replacing placard installation requirement with new actions.
Aforeworn detected this change in the Aviation Maintenance & Airworthiness (FAA) space on July 16, 2026 and published this briefing so affected operators are forewarned rather than caught off guard. It is rated Medium urgency. Operators and repair stations maintaining Leonardo AB139/AW139 helicopters under Part 135, 121, 145, or Part 91. should confirm how it applies to their specific situation before acting.
