## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to Hartzell Propeller Inc. HC-E4A-3(A,I,J) series propellers. This action requires a one-time inspection of the propeller blade counterweight clamps for thread damage in the bolt holes, and, if necessary, replacement with serviceable parts. This amendment is prompted by a report of a counterweight clamp bolt hole thread failure that resulted in the separation of the counterweight and the separation of a blade following impact with the counterweight. The actions specified in this AD are intended to prevent propeller blade counterweight clamp bolt hole thread failure, which can result in counterweight and propeller blade separation, and possible damage to the aircraft.
