ATL07LA021

According to the pilot, he lined up on runway 10 for takeoff, applied full power, and climbed the airplane straight ahead to approximately 500 feet above ground level (agl) and turned crosswind. While on crosswind, he noticed the power was diminishing. He turned downwind, still at about 500 ft agl. At about three-fourths of the way on downwind, he turned the airplane toward runway 10. At this point, he stated that he was not going to be able to put it on the runway. He was losing altitude quickly and noticed that the only place to put down was in the woods just northwest of the airport. Examination of the airplane by an FAA Inspector found that the pilot had installed a sheet metal pan with baffles around and over the engine cylinders. The baffles directed ram air over the cylinders for cooling. However, by doing so he inadvertently blocked the carburetor from ram air which resulted in the loss of engine power.

At this point, he stated that he was not going to be able to put it on the runway. He was losing altitude quickly and noticed that the only place to put down was in the woods just northwest of the airport. After impacting, he egressed the cockpit. Damage consisted of the wings, and empennage.

Examination of the airplane by an FAA Inspector found that the pilot had installed a sheet metal pan with baffles around and over the engine cylinders. The baffles directed ram air over the cylinders for cooling. However, by doing so he inadvertently blocked the carburetor from ram air. The pilot did not submit an NTSB Form 6120.1 Pilot/Operator report.
