ATC reported:
Aircraft 35 e of the boi VOR (43.34.86N,-115.52.89W) climbing thru 14800 when they declared an emergency for a lost prop. The aircraft returned to land at boi with 1 person on board.
Pilot statement:
I took off on a pop up charter to kapa airport. Departed around 0700 local (MDT). Following company procedures, did a run up checking both prop feathering and cycling-no anomalies noted. Climbed out at 2500 RPM and 32 inches manifold settings. All engine operations were normal. At approx. 14500 ft began slowly pulling engines and props back to level off at assigned altitude of 16000. At this time there was a brief vibration/noise (tough to describe), maybe 1-2 seconds long. I looked over and watched my left prop as it departed the aircraft. I identified and verified left engine controls and shut the engine down. Engine was still operating when the prop fell off. I declared an emergency and returned to Boise uneventfully.
