## Abstract

The FAA is superseding Airworthiness Directive (AD) 2025-09- 03, which applied to certain Bell Textron Canada Limited (Bell) Model 430 helicopters. AD 2025-09-03 reduced the life limits on the main rotor (M/R) clevises, universal bearings, and universal to pitch link bolts and required re-identifying the M/R pitch link assemblies with new part numbered assemblies. Since the FAA issued AD 2025-09-03, the FAA received comments proposing changes to the actions of AD 2025-09- 03. This AD requires changes to the actions in AD 2025-09-03 and addresses the comments received on that AD. The FAA is issuing this AD to address the unsafe condition on these products.
