What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot was spraying a wheat field in his AT-401. He was between 8 and 10 feet AGL going between 90 and 100KTS. He had 41 min of fuel remaining and 250 gal of chemicals in the spray hopper. Pilot reported the engine quit abruptly. Pilot stated he threw the prop and throttle full forward and began pumping the manual fuel pump all the way to the ground. He reported the fuel pressure was about 10LBS, oil pressure was bottomed out and the oil temerature was topped out at 240 degrees. He stated that he knew there was a ditch at the end of the field and that he didnt think he would have time to dump the load and still be able to clear the ditch. He deccided to keep the load and land straight ahead in the wehat. He touched down at about 100KTS and pinned the stick full back to keep the prop from striking the ground. He rolled through a small drainage ditch and it kicked the airplane up and the left wing tip hit the ground. The plane rocked back and the right wing tip hit but not as hard. The tail wheel was tore off when it went across the ditch. The plane came to a stop and the pilot reported seeing fire from the exhaust. He evacuated the plane and by the time he got out the fire was out. He stated that it was probaly built up fuel buring off from him pumping the manual fuel pump. The aircraft had flown just over 14 hours since the 100HR inspection. Pilot reported no injuries. The following morning I arrived at the sight. The plane was sitting in waist high wheat and I noticed oil spray down the left side of the fuselage. The left wing tip was bent and the sheet metal buckled up and the tip sheet metal was cracked with wheat hanging out. The tail wheel was folded to the side and drug the ground after landing. The aft fuselage area had a sheet metal dent. Upon removal of the fuelage panel I found a bent fuselage tube support. The right wing tip area had minor dents. There was no oil spray on the right side fuelsage area. Upon inspection of the engine I found a cracked valve cover on the 3 o'clock position jug. The oil spray on the left side aligned with this jug. The engine oil dipstick showed the oil level was low but not empty. It still had about 6 gal of oil. The aircraft and engine are being taken to a repair facility. The engine will be inspected for a cause. I will be following up with the operator on what they find with the engine.
