Final Report: Loss of power unexplained

Cessna 208B Caravan, Portland, Ore., Dec. 24, 2005–The reason for the Caravan’s loss of power on takeoff has not been determined, said the NTSB. The pilot reported, “After becoming airborne, the airplane quit accelerating and a positive climb rate was not established.”

The pilot’s pushing the power lever all the way forward did not help. Although the airplane became airborne, it did not climb and hit a cluster of antennas and a fence off the end of the runway. The engine compressor and power turbines showed moderate circular rubbing damage to the blades, suggesting that the engine was operating when the airplane hit.
