Analysis

After 30 minutes of local flight, on a dark night, the pilot increased the throttle setting after selecting approach flaps. There was no response from the engine. A forced landing was initiated and the aircraft collided with trees and terrain. A subsequent investigation of the engine, fuel supply, magnetos and induction system revealed nothing which would have prevented the engine from developing normal power.
