Détails:
A Cessna 208B airplane, N1324G, was substantially damaged during an off-airport landing near Bryans Corner, Oklahoma, following a loss of engine power while departing from Guymon Municipal Airport (GUY), Oklahoma. The pilot sustained minor injuries. Night visual meteorological conditions prevailed for the cargo flight, which had an intended destination of West Woodward Airport (WWR), Oklahoma.
While climbing through approximately 7,000 feet above mean sea level (MSL), the pilot reported that a loud bang occurred, followed by the propeller spooling down towards feather and stopping. The pilot attempted an unsuccessful air-start and an unsuccessful electric start. While trying to land on a two lane highway (U. S. Highway 412), the airplane hit a power line. The airplane subsequently suffered a hard landing, exited the highway on the left side, struck a power pole with the left wing tip and came to a stop within 50 feet of the north side of the highway.
An initial engine examination revealed mechanical and thermal damage to the turbine section of the engine.

Probable Cause:

PROBABLE CAUSE: "The total loss of engine power as a result of a fractured compressor turbine blade due to fatigue cracking. "
