## Probable cause

THE PILOT-IN-COMMAND'S FAILURE TO MAINTAIN PROPER VISUAL OUTLOOK.

## Sequence of events

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

- In flight collision with object, maneuvering - aerial application
  - object - tree(s)
  - visual lookout - inadequate, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - ground

## Analysis

THE COMMERCIAL PILOT WAS CONDUCTING AN AERIAL APPLICATION RUN TO THE NORTH. AFTER COMPLETING THE RUN THE PILOT INITIATED A PULL UP AND OBSERVED WIRES TO HIS IMMEDIATE FRONT. THE PILOT LOWERED THE NOSE OF THE AIRPLANE AND FLEW UNDER THE WIRES AND COLLIDED WITH TREES AND TERRAIN.
