Read the full NTSB narrative

THE ACFT LOST POWER AND MADE A FORCED LANDING IMMEDIATELY AFTER TAKEOFF ON AN AERIAL APPLICATION MISSION. THE LANDING GEAR COLLAPSED DURING THE LANDING. THE PILOT STATED THAT THE ACCIDENT OCCURRED ON THE 5TH FLT OF THE DAY AFTER TAKING OFF ON RUNWAY 27 AND WHEN CLIMBING TO 125 FT AGL THE ENGINE BEGAN TO LOSE POWER. THE PILOT REDUCED POWER AND LANDED STRAIGHT AHEAD 50 YDS OFF THE END OF TH TAKEOFF RUNWAY. AN EXAMINATION OF THE ENGINE REVEALED THAT THE LOWER PLUGS CONTAINED A DARK GREY DEPOSIT THAT BRIDGED THE ELECTRODES. THIS DEPOSIT WEAKENED THE SPARK PRODUCED BY THE PLUGS. WHEN CLEARED THEY PRODUCED A STRONGER SPARK.
