C-FHMD, a privately operated Cessna 414A aircraft, was conducting a positioning flight from Cranbrook/Canadian Rockies Intl (CYXC), BC to Calgary/Springbank (CYBW), AB with only the pilot on board.
During the final approach for Runway 17 at CYBW, the pilot heard a change in propeller sound for the right engine. A check of the engine instruments indicated that the oil pressure for the right engine (Teledyne Continental Motors TSIOL-550-A) was 0 PSI.
The pilot proceeded to feather the right propeller, secured the engine, and declared an emergency. An uneventful single-engine approach and landing was completed.
Maintenance personnel determined that the cause of the oil loss to be a worn bushing in the RH engine turbo charger.
