Airworthiness Directives; Hamilton Standard 14RF Series, 14SF Series, and Hamilton Standard/British Aerospace 6/5500/F Series Propellers Federal Register ↗

Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to Hamilton Standard 14RF series, 14SF series, and Hamilton Standard/British Aerospace 6/5500/F series propellers. This action requires a one-time inspection for cracks in the propeller blade taper bore. This amendment is prompted by reports of two incidents where the incident aircraft lost a portion of a propeller blade inflight. The actions specified in this AD are intended to prevent loss of a propeller blade due to cracks initiating in the blade taper bore, that can result in possible aircraft damage, and possible loss of aircraft control.
