            Please elaborate on the failure of your older 2 blade MT prop, and the “metallurgical” problems on their early models.  My older MT was overhauled 2 years ago by Sullivan Propeller Last year, I experienced a pitch change failure resulting from the pinion gear debonding from the electric motor shaft.  The prop remained fine pitch, the overspeed was immediately detected, and I performed a precautionary landing.  I pulled the prop, rented a car, drove home, and had it repaired the next week.  If there are serious metallurgical issues with propellers that are in service, I would like to know!
