On December 9, 1996, at 1130 eastern standard time, a Pereyra Aventura II, N32913, collided with the ground during an attempted emergency landing near Rockledge, Florida. The personal flight operated under the provisions of Title 14 CFR Part 91 with no flight plan filed. Visual weather conditions prevailed at the time of the accident. The experimental airplane sustained substantial damage. The pilot received minor injuries, and the passenger was not injured. The flight departed a private airstrip near Rockledge, Florida, at 1035. Before takeoff, the pilot completed a preflight inspection and an engine runup, and reported that all systems were normal. He further stated that, as the airplane climbed through 400 feet, following the takeoff, the engine lost power. After attempts by the pilot to restart the engine failed, he selected a paved road for the forced landing area. During the landing roll the pilot realized that he could not negotiate a turn in the road. At this point, he elected to continue the landing roll out off the road into an adjacent rock quarry below the level of the road surface. The examination of the airplane and the two stroke engine assembly at the accident site failed to disclose a mechanical problem. The examination confirmed that all engine accessories and sub-systems were capable of normal operation.
