Airworthiness Directives; Airbus Helicopters

The FAA proposes to supersede Airworthiness Directive (AD) 2026-12-09, which applies to all Airbus Helicopters Model AS350B, AS350BA, AS350B1, and AS350D helicopters. AD 2026-12-09 requires revising the airworthiness limitations section (ALS) of the existing maintenance manual (MM) or instructions for continued airworthiness (ICA) and the existing approved maintenance or inspection program, as applicable. Since the FAA issued AD 2026-12-09, a determination was made that new and more restrictive airworthiness limitations and maintenance tasks are necessary. This proposed AD would require incorporating these airworthiness limitations into the ALS of the existing MM or ICA and the existing approved maintenance or inspection program, as applicable. The FAA is proposing this AD to address the unsafe condition on these products.
