What was found
(CAN) WHILE RETURNING TO THE AIRPORT, THE ACFT RT ENGINE FAILED AND THE PROPELLER WAS THEN FEATHERED. TO THE BEST OF MY KNOWLEDGE, APPROXIMATELY 18 MINUTES LATER, THE SECOND ENGINE FAILED AND THAT PROPELLER WAS ALSO FEATHERED. AN EMERGENCY LANDING WAS THEN CARRIED OUT. AS THE ACCIDENT IS UNDER THE INVESTIGATION OF THE TSB, NO DIRECT CAUSE HAS BEEN ESTABLISHED.
