FAA Issues Airworthiness Directive Amendment for Hamilton Standard Propellers

The FAA has issued an airworthiness directive (AD) amendment for Hamilton Standard 14RF series, 14SF series, and Hamilton Standard/British Aerospace 6/5500/F series propellers, requiring initial and repetitive ultrasonic shear wave inspections, as well as a one-time visual and borescope inspection of the taper bore for corrosion. The move comes after reports of two incidents where a portion of the propeller blade was lost in flight.
