Probable cause

Analysis

The plt aborted the first takeoff attempt due to the door opening. On the second attempt the acft climbed to aprx 300 ft, turned 90 degs left then back to the rwy heading. The nose descended and the acft impacted a field in a vertical dive. Fire began apx 15 seconds following impact and the acft was consumed by fire. Examination of the wreckage revealed the cabin door to have separated from the acft at impact and the top latch, a 'j' hook, was fractured and missing.
