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
The plt reported weather conditions during the night aerial application flt were 'clear and winds of 15 KTS with gusts to 20 KTS. After three unsuccessful attempts to line up for the spray run, the plt said he allowed the acft to 'get too low and slow' while turning for another run and was late recognizing the problem and adding power. As the acft settled toward the ground, the plt tried to jettison the hopper load with less than full dump gate control handle movement, but the gate did not function. After touchdown in the plowed field, the acft nosed over. Functional testing of the dump gate after the accident revealed that it worked with full control handle movement.
