Traduction automatique locale · Langue originale de la source
Résumé
The Federal Aviation Administration (FAA) proposes to adopt 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 De-icing) 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 proposal would require removal of the anti-ice boots, rework of the anti-ice boot area of the propeller blades, and installation of new anti-ice boots. This proposal is prompted by a report of TKS (Aircraft De-icing) Ltd. anti-ice boots on the blades of a model HC-C2Y(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 the proposed AD are intended to prevent propeller blade separation, damage to the airplane, and possible loss of the airplane.
