The private certificated pilot/owner, along with a flight instructor, departed on the initial portion of a CFR Part 91 flight review. The airplane engine began to lose power about 50 feet agl, and would not maintain altitude. A forced landing area was selected on a road, but the airplane struck several trees before colliding with the ground. An FAA inspector reported that an examination of the engine disclosed that the number 1 cylinder had no compression because the exhaust valve was stuck in the open position, resulting in a substantial loss of engine power. Additionally, the inspector found that the airplane was about 70 pounds over its maximum gross weight, reducing its climb performance.
Probable Cause: A partial loss of engine power due to a stuck engine exhaust valve during takeoff initial climb. A contributing factor was the airplane's excessive gross weight.
