Notice of proposed rulemaking (NPRM).

The FAA proposes to supersede Airworthiness Directive (AD) 2025-09-03, which applies 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, universal to pitch link bolts, the tube assembly, and the rod end assembly and requires replacing the M/R pitch link assemblies with re-identified 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 proposed AD proposes changes to actions in AD 2025-09-03 and addresses the comments received. The FAA is proposing this AD to address the unsafe condition on these products.
