Read the full NTSB narrative

THE PLT SAID HE WAS SPRAYING 2,4,D ON TWO BARLEY FLDS. HE HAD COMPLETED ONE FLD AND WAS TURNING AROUND WHEN THE ACFT BEGAN TO SETTLE. HE SAID WHEN HE ATTEMPTED TO AVOID GROUND CONTACT THE ACFT STALLED AND COLLIDED WITH THE GROUND. DURING A TELEPHONE CONVERSATION ON THE DAY OF THE ACCIDENT THE PLT SAID THERE WAS NOTHING WRONG WITH THE ACFT OR ENG AND THAT HE JUST MUST HAVE HIT 'DEAD AIR' (A DOWNDRAFT OR TAILWIND). SEVERAL DAYS AFTER THE ACCIDENT THE PLT REPORTED THAT IN HIS OPINION THE ENG WAS NOT PRODUCING POWER AT THE TIME OF THE ACCIDENT. THE ENG WAS THEN DISASSEMBLED BUT NO EVIDENCE TO SUPPORT A LOSS OF PWR WAS FOUND.
