SUMMARY: This amendment adopts a new airworthiness directive (AD), that is applicable to certain Hartzell Propeller Inc. model HC-C2Y(K,R)-1BF/F8477-4 propellers with TKS (Aircraft Deicing) Ltd. anti-ice boots that were installed by SOCATA-Groupe AEROSPATIALE, the aircraft manufacturer, using TKS Ltd. Procedure P232, Specification for the Attachment of Propeller Overshoes. This amendment requires removal of the anti-ice boots, inspection and rework of the antiice boot area of the propeller blades, and installation of new anti-ice boots. This amendment is prompted by a report of TKS (Aircraft De-icing) Ltd. anti-ice boots on the blades of a model HCC2Y(K,R)-1BF/F8477-4 propeller that were installed by SOCATA-Groupe AEROSPATIALE using processes that could lead to blade corrosion and failure. The actions specified by this AD are intended to prevent propeller blade separation, damage to the airplane, and possible loss of the airplane.
