Probable cause

The pilot's inability to maintain control of the gyrocraft during a forced landing as a result of a loss of cyclic and collective control. Contributing factors were the sheared propeller drive pulley bolts, broken wire on the co-pilots cyclic boost control solenoid, failure of the ballistic parachute to deploy, and the lack of suitable terrain for forced landing.

Read the full NTSB narrative

During a research and development flight, the gyrocraft was flying at an airspeed of 151 miles per hour when the 2,400-hour pilot heard a noise from the engine compartment. The pilot stated that the gyrocraft started to roll to the left despite control inputs. After an unsuccessful attempt to deploy the onboard ballistic parachute, the pilot initiated a forced landing. The pilot attempted to flare using the control stick only and "did not pull collective." Subsequently, the gyrocraft impacted trees before hitting the ground. An examination of the gyrocraft revealed that bolts holding the propeller drive pulley to the propeller drive shaft were "sheared" and a wire to the co-pilot cyclic boost control solenoid was separated.
