A Cessna 208B Supervan 900 airplane, N10JA, was substantially damaged when it was involved in an accident in Oceanside, California. The pilot and passenger were seriously injured.
The pilot stated that the pilot-rated passenger was spending the day observing the skydiving operation. He had made three consecutive flights climbing to around 13,000 feet mean sea level (msl) to unload the skydivers. On the fourth flight, the pilot departed runway 25 and made a gradual climb to 12,700 ft msl as he circled back to the airport. The skydivers departed the airplane and the pilot initiated a steep, turning descent with the power at idle. He stated that
the airplane was in “beta mode” but that the power lever was above the flight idle gate and the speed lever was left in the high position. The pilot stated that, while the airplane was on the base leg of the traffic pattern to runway 25, at an altitude about 4,000 ft msl and a descent rate of 4,500 fpm, he attempted to arrest the descent by adding power.
The pilot further stated that despite his attempt to add power, the engine did not respond to movements of the power lever. He moved the propeller speed lever, which also had no effect. The pilot presumed that the engine had flamed out and attempted a restart. With the propeller still windmilling, he switched the ignition to “continuous” and turned the boost pump on. He observed the torque gauge increase from 0% to 20%, but the engine was still unresponsive to movements of the power lever. He applied full nose-up trim and pulled the control yoke full aft against the stop, but the airplane would not maintain a level attitude. With the airplane in a noselow attitude, it collided with terrain about 1,400 ft short of the runway below). The pilot did not feather the propeller.
Probable Cause
The pilot’s intentional inflight operation of the propeller in beta, which led to an aerodynamic lock, his inability to restore forward thrust, and subsequent collision with terrain.
