Read the full NTSB narrative

THIS EXPERIMENTAL ACFT IS POWERED BY A MODIFIED HONDA 1250 CC, WATERCOOLED ENG. THE PLT REPORTED THAT AFTER TAKEOFF THE ENG TEMP REACHED THE REDLINE AND THE ENG LOST POWER. DURING THE FORCED LANDING THE MAIN LANDING GEAR COLLAPSED. EXAMINATION OF THE ENG AFTER THE ACDT REVEALED THAT A HOLE WAS BURNED IN THE #4 PISTON AND A PORTION OF THE HEAD GASKET BETWEEN THE #3 AND #4 CYL WAS MISSING. THE OWNER AND TECHNICIANS FAMILIAR WITH THE ENG SUGGEST A LARGER RADIATOR, RETIMING OF THE IGNITION, AND/OR A RICHER MIXTURE MAY PRECLUDE RECURRENCE OF THE PROBLEM.
