Beschrijving:
The Cessna 208B, N106BZ, collided with terrain and trees during an off airport forced landing in Verdigris, Oklahoma. The force landing was a result of a loss of engine power during an en route climb. The pilot received minor injuries and the passenger was not injured. The airplane was substantially damaged. The aircraft was owned and operated by the pilot as post maintenance test flight. Visual meteorological conditions prevailed for the flight. The flight originated from the Tulsa International Airport, Oklahoma, at 15:00.
The airplane was equipped with a Honeywell TPE331 engine which had been installed about 9 flight hours prior to the accident. The pilot stated they were climbing to 11,000 feet when he noticed a decrease in engine torque with a steady exhaust gas temperature (EGT). As the torque started to drop even more, the EGT also began to decrease.
The pilot attempted to fly to a nearby airstrip, but was unable to maintain sufficient altitude. He then chose a field in which to land. Shortly after touching down, the airplane contacted trees, completely severing the left wing from the fuselage and partially severing the right wing from the fuselage.

Probable Cause:

PROBABLE CAUSE: "The fuel pump gear manufacturer’s allowance of set-up gears made from a nonconforming material to be put in the production inventory system, the installation of a nonconforming gear in the accident airplane’s production fuel pump, and the gear’s failure, which resulted in a loss of fuel flow to the engine and the subsequent loss of engine power."
