Summary
The FAA is superseding Airworthiness Directive (AD) 2019-12-18 for Robinson Helicopter Company (Robinson) Model R44 II helicopters. AD 2019-12-18 required inspecting certain engine air induction hoses (hoses) and replacing any hose that was not airworthy. AD 2019-12-18 also prohibited the installation of certain hoses. This AD continues to require inspecting those previously affected hoses and amends the applicability, clarifies an inspection requirement, adds a requirement to repeat the inspection, and expands the installation prohibition. This AD was prompted by an additional report of separation between the outer and inner hose layers. The FAA is issuing this AD to address the unsafe condition on these products.
