FAA Proposes Update to Airworthiness Directive for Turbomeca Arriel 1B, 1D, 1D1, and 1S1 Turboshaft Engines

The Federal Aviation Administration (FAA) is proposing to update an existing airworthiness directive for certain Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines to prevent failures of 2nd stage turbine blades, which could lead to engine shutdowns and accidents, following recent reports of new cases of blade failures since 2008.
