Airworthiness Directives; Robinson Helicopter Company Helicopters

AD 2025-01949 Published 2025-01-30 1 model 550 US-registered tails affected Federal Register ↗

Abstract

The FAA proposes to supersede Airworthiness Directive (AD) 2024-19-11, which applies to all Robinson Helicopter Company Model R44 and R44 II helicopters. AD 2024-19-11 requires visually inspecting a certain flex plate assembly (flex plate) and certain clutch shaft forward yokes (yokes), including each flex plate bolt, and depending on the results, taking corrective actions. AD 2024-19-11 also requires removing certain yokes from service within a specified threshold, or as an alternative, performing in-depth inspections. Since the FAA issued AD 2024-19-11, it has been determined that clarifications regarding the alternative inspections are necessary. This proposed AD would retain all the requirements of AD 2024-19-11 and would clarify that the alternative inspections are repetitive and add a particular paint remover option to use when performing those alternative inspections. The FAA is proposing this AD to address the unsafe condition on these products.

Applicability

Aircraft makes and models this AD applies to, sorted by US-registered fleet size.
