Airworthiness Directive · Amendment 39-10154 · MT-Propeller Entwicklung GMBH Model MTV-3-B-C Propellers
MT-Propeller Entwicklung GMBH Model MTV-3-B-C Propellers
MT-Propeller Entwicklung GMBH Model MTV-3-B-C/ L250-21. These propellers are installed on but not limited to Sukhoi 29 aircraft.
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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
