Analysis

The owner/plt had previous flown the home built acft which was constructed similar to an ultralight. An optional pilot enclosure (canvas covering over the plt compartment) had just been installed. On 7/7/84, the owner/plt taxi checked the acft for about 30 min, then elected to takeoff. The takeoff area was on rolling/hilly terrain with the 1st part of the takeoff roll proceeding uphill. The acft became airborne, but according to the plt, he could not clear trees. He maneuvered to avoid the trees, but subsequently stalled & crash landed. An investigation revealed no evidence of a part failure or malfunction.
