FAA 2023–12–26

Supersedes AD 2021–24–04, which required revising the existing rotorcraft flight manual (RFM). Since the FAA issued AD 2021–24–04, Bell revised the RFM to incorporate more restrictive operating limitations. This AD is prompted by the determination that the existing altitude limitations were not valid for certain fuel types and that revising the existing RFM to align with the limitations of the Safran Arrius 2R engine is necessary. This AD requires revising the existing RFM as specified in a Transport Canada AD.
