failure of the number 8 cylinder, which resulted in loss of engine power, a forced landing in soft terrain, and subsequent nose over of the airplane.

Read the full NTSB narrative

After performing a number of previous aerial application flights, the airplane was loaded with a chemical pesticide, and the pilot initiated a takeoff from runway 20. Immediately after liftoff, the engine began missing, smoking, and backfiring violently. When the pilot was not able to maintain airspeed, he dropped the 207 gallons of pesticide, and made a forced landing straight ahead in a freshly plowed field. During the landing, the main gear sank into the topsoil, and the airplane nosed over. Examination of the engine revealed that the number eight cylinder head was cracked open from the forward spark plug boss to the rear spark plug boss, and the crack had progressed down to the cylinder barrel.
