Probable cause
Total failure of the engine connecting rod.
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
During the local flight of the experimental airplane, a connecting rod broke in the engine. The pilot was able to make it back to the airport for a forced landing but was unable to land on the runway due to another airplane that taxied onto the runway in front of the approaching airplane. The airplane made an off-runway, hard landing, and both landing gears collapsed. The plt did not file an acc report.
