## Probable cause

THE PILOT-IN-COMMAND'S NOT MAINTAINING PROPER ALTITUDE.

## 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
  - proper altitude - not maintained, pilot in command (cause)
  - diverted attention, pilot in command (contributing factor)

## Analysis

THE PILOT WAS MAKING PRACTICE AERIAL APPLICATION MANEUVERS WHEN HIS ATTENTION WAS DISTRACTED TO A FLOW DEVICE IN THE COCKPIT.  WHILE HIS ATTENTION WAS INSIDE THE AIRPLANE THE AIRPLANE DESCENDED INTO THE TERRAIN.
