AD 2026-15-06 Airworthiness Directives; Bell Textron Canada Limited Helicopters
Models named: 505. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Bell Textron Canada Limited Model 505 helicopters, certificated in any category, as identified in Transport Canada AD CF-2025-32, dated July 2, 2025 (Transport Canada AD CF-2025-32).
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Transport Canada AD CF-2025-32.
Unsafe condition
This AD was prompted by multiple occurrences of the vertical stabilizer top end cap assembly being found cracked, with some cases including the departure of the navigation/very high frequency omni-directional range/glide slope antenna and tuning weight from the helicopter during flight. The FAA is issuing this AD to address cracking in the vertical stabilizer top end cap assembly. The unsafe condition, if not addressed, could result in the antenna or tuning weight departing from the helicopter and impacting and damaging the tail rotor, which could result in the loss of directional control of the helicopter.
Affected ADs
This AD replaces AD 2024-02-55, Amendment 39-22674 (89 FR 14576, February 28, 2024).
