The FAA proposes to adopt a new airworthiness directive (AD) for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42 airplanes; and Model ATR72 airplanes. This proposed AD was prompted by in-service data which revealed that the minimum operating airspeeds in severe icing conditions, computed to provide adequate stall margins, do not provide sufficient margins to stall speeds at high bank angle while exiting severe icing conditions. This proposed AD would require revising the existing aircraft flight manual (AFM) and applicable corresponding operational procedures to provide emergency procedures and limitations for operating in severe icing conditions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
