Flight Crew Rejected Takeoff
Aircraft
Upon applying takeoff power while on the runway. The engine began making power. Then without notice or hesitation; the airplane began yawing hard to the right. I aborted the takeoff and while re-centering the airplane on the runway noticed that the right engine was no longer running. It had died during the application of takeoff power.
C402 Captain reported a rejected takeoff due to an uncommanded yaw from an engine rollback.
