The Federal Aviation Administration (FAA) is adopting a new airworthiness directive (AD) for certain Leonardo S.p.A. helicopters. This applies to Model A109A, A109A II, A109C, A109K2, A109E, A119, AW119 MKII, and specific A109S and AW109SP models.

Why it matters: This is a standard safety fix. An incorrectly installed bearing in a rotor system can lead to mechanical failure. The action is narrow, targeting a specific component on specific aircraft models, rather than a broad fleet-wide issue.

Who it affects

  • Owners and operators of the listed Leonardo helicopter models

The Federal Aviation Administration published this rule in the Federal Register; check the original document for specific part numbers and compliance deadlines.
