Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
Very shortly after takeoff the pilot heard a 'hissing sound' and immediately started dumping his chemical load. He was holding the nose up in an effort to stay airborne and complete the dump when all power was lost. The airplane then stalled from about 20 feet and nosed over upon impact. An FAA inspector reported that there was a crack in the combustion chamber area of the number nine cylinder, which ran fore and aft through the sparkplug holes.
