Airworthiness Directives; Airbus Helicopters

官方摘要

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC 155 B and EC 155 B1 helicopters. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD 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. The FAA is issuing this AD to address the unsafe condition on these products.
