Accident Overview
A pilot reported having little recollection of an accident that occurred while conducting agricultural spraying operations. The pilot had been applying a 50-50 mixture of Furadan and Dimate 4E to a field.
Witness Accounts
Witnesses at the scene stated that they heard the engine 'cut out,' 'stall,' or 'stop' during the flight. They then heard the engine restart before it 'cut out,' 'stalled,' or 'stopped' a second time. Following the second power loss, witnesses observed the airplane 'dive,' 'nose dive,' or go 'straight down.'
Post-Accident Examination
An FAA inspector conducted an examination of the aircraft. The inspection focused on the fuel system. The wing tanks, which were undamaged, showed no evidence of fuel. No fuel was detected in the gascolator, the fuel line between the gascolator and fuel pump, or the carburetor. A small amount of fuel was found in the carburetor inlet fuel line.
