## Abstract

The FAA is superseding Airworthiness Directive (AD) 2025-07- 06, which applied to all Airbus Helicopters Model H160-B helicopters. AD 2025-07-06 required measuring the axial play of the rotating scissors spherical bearings and depending on the results, accomplishing corrective action and reporting inspection results. Since the FAA issued AD 2025-07-06 a determination was made that repetitive inspections for axial play measurements on non-rotating scissors spherical bearings are necessary. This AD retains all of the actions required in AD 2025-07-06 and extends the definition of an affected part to include all serial numbered non-rotating scissors spherical bearings. This AD also prohibits installing affected rotating and non- rotating scissors spherical bearings unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
