Probable cause

A loss of engine power due to the partial blocked carburetor fuel screen which resulted in partial fuel starvation and the pilot's failure to maintain adequate airspeed during the forced landing which resulted in an inadvertent stall. A factor associated with the accident was the low altitude at which the loss of engine power occurred.

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(partial) - nonmechanicalTakeoff - initial climb
Fuel system,screen - foreign material/substanceCause
Fluid,fuel - starvationCause
Forced landingEmergency landing after takeoff
Altitude - lowFactor
Loss of control - in flightManeuvering - turn to landing area (emergency)
Airspeed - inadequatePilot in commandCause
Stall - inadvertentPilot in commandCause
In flight collision with terrain/waterDescent - uncontrolled
Terrain condition - ground

Analysis

The airplane impacted the terrain in a field following a loss of engine power on takeoff. The pilot reported that the engine start and run up were normal. He stated that the engine lost power and restarted when they were about half way down the runway during the takeoff. He stated this occurred again when they were too far down the runway to abort the takeoff. The pilot reported that there were high-tension lines in front of them so he descended to fly under the lines. He then saw lower power lines near the road. He was able to fly above these lines. The pilot reported that the engine power continued going on and off during this period. The pilot reported the airplane was about tree top height when he banked to the left and then to the right to line up with a field. It was during this time the airplane stalled and impacted the ground. Inspection of the airplane and engine revealed that approximately one third of the carburetor fuel screen was plugged by dirt. No other mechanical failures/malfunctions were identified.

Factual narrative

The airplane impacted the terrain in a field following a loss of engine power on takeoff. The pilot reported the engine start and run up were normal. He stated that the engine quit and restarted when they were about half way down the runway during the takeoff. He stated this occurred again when they were too far down the runway to abort the takeoff. The pilot reported there were high-tension lines in front of them so he descended to fly under the lines. He then saw lower power lines near the road. He was able to fly above these lines. The pilot reported that the engine power continued going on and off during this period. The pilot reported the airplane was about tree top height when he banked to the left and then to the right to line up with a field. It was during this time the airplane stalled and impacted the ground.

Inspectors from the Federal Aviation Administration Flight Standards District Office in Belleville, Michigan examined the airplane and engine. The inspectors reported the magnetos produced spark and thumb compression was achieved on all the cylinders. The carburetor was inspected and it was determined that approximately one third of the fuel screen was plugged by dirt. No other mechanical failures/malfunctions were identified.

The pilot's last medical certificate was a Third Class medical dated April 2, 1999.
