Bell Textron Canada Limited Helicopters
This AD applies to Bell Textron Canada Limited Model 505 helicopters, certificated in any category, as identified in Transport Canada AD CF-2024-44, dated December 19, 2024 (Transport Canada AD CF-2024-44).
The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited (BTCL) Model 505 helicopters. This AD was prompted by reports of possible chafing in certain locations between the basic and supplemental helicopter wiring and the structure. This AD requires repetitively inspecting the wire harnesses at certain locations for damage, and if any wire damage is found, repairing the damaged wire/bundles, 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-2024-44.
(1) Where Transport Canada AD CF-2024-44 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where Transport Canada AD CF-2024-44 refers to hours airtime, this AD requires using hours time-in-service.
(3) Where the material referenced in Transport Canada AD CF-2024-44 states to contact Bell Product Support Engineering if the fouling condition cannot be rectified, this AD requires contacting the Manager, International Validation Branch, FAA; Transport Canada; or Bell Textron Canada Limited's Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
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.
