Airworthiness Directives; Airbus Helicopters

AD 2026-00137 Published 2026-01-08 2 models 455 US-registered tails affected Federal Register ↗

Abstract

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS350B2, AS350B3, EC130B4, and EC130T2 helicopters. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the airworthiness limitations section (ALS) of the existing maintenance manual (MM) or instructions for continued airworthiness and the existing approved maintenance or inspection program. The FAA is proposing this AD to address the unsafe condition on these products.

Applicability

Aircraft makes and models this AD applies to, sorted by US-registered fleet size.
