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

- In flight collision with terrain/water, maneuvering - aerial application
  - clearance - misjudged, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (contributing factor)
  - landing gear,main gear strut - overload (contributing factor)
- Main gear collapsed, maneuvering - aerial application
- Loss of control - on ground/water, landing - flare/touchdown
  - ground loop/swerve - uncontrolled, pilot in command
- Nose over, landing - roll

## Analysis

THE PILOT WAS ON A FLIGHT TO PRACTICE AERIAL APPLICATION. THIS WAS HIS FIRST FLIGHT IN THIS MAKE AND MODEL OF AIRCRAFT. WHILE MAKING A PRACTICE RUN OVER AN OPEN FIELD WITH WATER IN THE CHEMICAL TANKS, THE LEFT MAIN GEAR CONTACTED THE GROUND DAMAGING THE STRUT. THE PILOT RETURNED TO THE AIRPORT, BUT DURING THE LANDING, THE LEFT MAIN GEAR COLLAPSED. SUBSEQUENTLY, THE AIRCRAFT GROUND LOOPED, THEN FLIPPED OVER ON ITS BACK.
