Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters

摘要

The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 A-3, MBB-BK 117 A-4, MBB-BK 117 B-1, MBB-BK 117 B-2, and MBB-BK 117 C-1 helicopters. This AD was prompted by reports that the adhesive seal prevented the doors from jettisoning properly. This AD requires removing certain seals, replacing certain seals with newly certified seals and revising the existing Rotorcraft Flight Manual (RFM) for your helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
