Airworthiness Directive · Amendment 39-22485 · Engine fuel and control
Bell Textron Canada Limited Helicopters
This AD applies to Bell Textron Canada Limited Model 505 helicopters having a serial number 65011 and subsequent, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2021-24- 04, which applied to certain Bell Helicopter Textron Canada Limited (type certificate previously held by Bell Helicopter Textron Canada Limited) Model 505 helicopters. AD 2021-24-04 required revising the existing Rotorcraft Flight Manual (RFM) for your helicopter. Since the FAA issued AD 2021-24-04, Bell Textron Canada Limited 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 for your helicopter to align with the limitations of the Safran Helicopter Engines, S.A. Model ARRIUS 2R engine is necessary. This AD requires revising the existing RFM for your helicopter, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Transport Canada AD CF-2023-16, dated March 6, 2023 (Transport Canada AD CF-2023-16). The owner/operator (pilot) holding at least a private pilot certificate may revise the existing Rotorcraft Flight Manual for your helicopter and must enter compliance with this AD into the aircraft records in accordance with 14 CFR 43.9(a) and 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 121.380, or 135.439.
Where Transport Canada AD CF-2023-16 refers to its effective date, this AD requires using the effective date of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
