Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to MT-Propeller Entwicklung GMBH Model MTV-3-B-C propellers. This action requires initial and repetitive dye penetrant or eddy current inspections for cracks in the propeller hub, and rework of the propeller hub or replacement with a new model propeller hub. This amendment is prompted by reports of cracks in the propeller flange area of the hub detected during overhaul. The actions specified in this AD are intended to prevent propeller hub cracks, which could result in propeller blade separation and possible loss of control of the aircraft.
