## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- In flight collision with terrain/water, maneuvering - aerial application
  - preflight planning/preparation - inadequate, pilot in command (cause)
  - weather condition - high density altitude (cause)
  - terrain condition - rising (cause)

## Analysis

THE ACFT WAS LOADED WITH 1500 LBS OF DRY CHEMICAL (FERTILIZER). THE AIR TEMP AT THE TIME OF THE ACCIDENT WAS 95 DEG F, RESULTING IN A HIGH DENSITY ALT. RISING TERRAIN EXISTED AT THE POINT WHERE THE PLT ATTEMPTED A TURNAROUND. IN AN ATTEMPT TO TURN AWAY FROM THIS RISING TERRAIN, THE RIGHT MAIN LANDING GEAR STRUCK THE GROUND FOLLOWED BY RIGHT WING CONTACT. THE ACFT CAME TO REST UPRIGHT. THE PLT STATED THAT HE DECREASED ANGLE OF BANK AND CLIMB, ADDED FULL PWR AND BEGAN DUMPING HIS CHEMICAL LOAD, BUT GROUND CONTACT COULD NOT BE AVOIDED DURING THE TURN.
