Airworthiness Directives; Bell Textron Canada Limited Helicopters

Document 2026-12480 is a Proposed Rule published by the Department of Transportation in the Federal Register on June 22, 2026. The FAA proposes to adopt a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 505 helicopters. This proposed AD was prompted by reports that the identification plate affixed to certain tail cone assemblies contains an incorrect part number (P/N), which may not accurately convey the life limit. This proposed AD would require verifying the tail cone assembly part number and, if necessary, replacing the incorrect tail cone assembly identification plate with a new tail cone assembly identification plate containing the correct P/N and updating the existing log card or equivalent record for the helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
