Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During an aerial application applying sulphur, the sulphur ignited inflight. The pilot turned the aircraft back toward the airport; however, the cockpit filled with smoke and the pilot decided to land on a road. Due to the extent of fire damage it could not be determined how the sulphur ignited. The pilot reported no mechanical failures or malfunctions prior to the accident.
