At 1100 eastern time, a Cessna 150F lost power on initial climb from Suffolk Municipal Airport. The pilot was not injured. The pilot said he had just taken off when the engine lost total power. The pilot performed a forced landing to a wooded area, where the airplane collided with trees. Examination of the engine revealed that the number four cylinder had separated at the mid-point on the barrel. The engine had been overhauled in 1994 and had accumulated about 800 hours of operation since then.
