## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to Hamilton Standard 54H60 series propellers. This action requires removing from service affected propeller blades, and returning those blades to the manufacturer or an approved facility for inspection, rework, and return to service. This amendment is prompted by reports of a propeller blade manufacturing defect. The actions specified in this AD are intended to prevent propeller blade fracture due to the manufacturing defect, which could result in propeller blade separation and loss of control of the aircraft.
