Airworthiness Directives; Airbus Helicopters

Built by the Tribune's code from the Federal Register. No AI wrote this page. Published in the Federal Register July 2, 2026. Document 2026-13368. Updated Nov. 8, 2026.

What it does

The FAA proposes to supersede Airworthiness Directive (AD) 2025-13-09, which applies to all Airbus Helicopters Model AS-365N2, AS 365 N3, EC 155B, EC155B1, SA-365N, and SA-365N1 helicopters. AD 2025- 13-09 requires inspecting the tightening torque, reporting the results of the inspections, and, depending on the results of the inspection, taking corrective action. Since the FAA issued AD 2025-13-09, the manufacturer determined that additional inspections of the main rotor (MR) servo-controls nut torque should be required. This proposed AD would retain some of the actions of AD 2025-13-09 and would also require additional inspections and, depending on the results of the inspection, corrective actions. This proposed AD would also require reporting certain information to the manufacturer. The FAA is proposing this AD to address the unsafe condition on these products.
