N69TT

The pilot stated that he had made a low approach to runway 24, at Flagler Airport, Bunnell, Florida, and had climbed out, with full power being applied. He further stated that after the airplane had climbed to about 200 feet, it stopped gaining altitude, while all systems were operating normally, and normal takeoff power was being generated. He said that the airplane would only gain altitude when being flown into the wind, and at that point he knew that something was wrong, so he returned to the airport, while trying to maintain 300 feet altitude. He said that the airplane would not maintain altitude or climb, and it was as if there was a microburst pushing him down. With full power applied, and the airplane continuing to function normally, the pilot said it descended, and impacted the ground.
