Airworthiness Directives; Bell Textron Canada Limited Helicopters

Built by the Tribune's code from the Federal Register. No AI wrote this page. Published in the Federal Register Sept. 10, 2026. Document 2026-18468. Updated Nov. 6, 2026.

What it does

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 a quality escape affecting certain tailcone assemblies. This proposed AD would require replacing any tailcone assembly that has exceeded a certain life limit. Also, this proposed AD would require inspecting the tailcone assembly for gaps, and repetitively inspecting the tailcone assembly for loose, damaged, or missing fasteners. Depending on the results of these inspections, this proposed AD would require conducting further inspections and corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
