Supersedes 2018-17-01
Supersedence is read from the Federal Register text of the newer AD — the FAA publishes no structured field for it — and names only ADs held in our index.
Corrects: This AD was prompted by the discovery that we omitted a helicopter model from one of the required actions.
Full official abstract
We are superseding Airworthiness Directive (AD) 2018-17-01 for Bell Model 212, 412, 412CF, and 412EP helicopters. AD 2018-17-01 required replacing certain oil and fuel check valves and prohibited installing these valves on any helicopter. This AD retains the requirements of AD 2018-17-01 but expands those requirements for all model helicopters. This AD was prompted by the discovery that we omitted a helicopter model from one of the required actions. We are issuing this AD to address the unsafe condition on these products.
