Engine Turbine/Turboshaft — RPM (N2) Steady-State Operation Avoidance Range Limit

The Airworthiness Directive CF-2018-23 issued by Transport Canada mandates updated operating limitations for the engine turbine/turboshaft RPM (N2) steady-state operation avoidance range on Bell Helicopter Textron Canada Limited (BHTCL) model 206B and 206L series helicopters. This directive addresses issues related to Rolls Royce 250-C20 Series engine turbine wheel failures by expanding the RPM avoidance range and requiring amendments to the Rotorcraft Flight Manual and installation of a new decal. It applies specifically to certain serial numbers of model 206B and 206L helicopters and excludes those modified by specific Supplemental Type Certificates.
