Summary
We are superseding Airworthiness Directive (AD) 2017-15-02 for Bell Model 212 and 412 helicopters. AD 2017-15-02 required replacing certain oil and fuel check valves and prohibited installing them on any helicopter. This AD retains the requirements of AD 2017-15-02 and adds certain model helicopters to the applicability. This AD was prompted by the discovery of an error in the affected models. We are issuing this AD to address the unsafe condition on these products.
