Probable cause

Pilot's failure to properly adjust the throttle friction which resulted in the disconnection of the entire assembly.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Loss of engine power(total) - mech failure/malfApproach - vfr pattern - final approach
Throttle/power lever,bellcrank - disconnectedCause
Throttle/power control friction lock - improper use ofPilot in commandCause
Forced landingDescent - emergency
In flight collision with objectDescent - emergency
Object - tree(s)

Analysis

During the preflight inspection the pilot reported that the throttle was stiff. He released the friction, but the throttle lever remained stiff. Shortly after takeoff the throttle friction knob fell from the throttle assembly. The pilots recovered the knob, but were unable to replace the knob. During the approach to Wilmington, the pilots reduced the throttle and the engine quit. The pilots could not advance the throttle. The airplane crashed landed into trees short of the airport. A subsequent examination disclosed that the friction knob is also the axle which supports the throttle and propeller levers. Thus, its removal prevented normal operation of the throttle assemble.
