## Probable cause

the pilot stalled the airplane while manuevering to avoid the power lines.  A factor was the power lines.

## Sequence of events

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

- Loss of control - in flight, maneuvering - aerial application
  - maneuver to avoid obstructions - attempted, pilot in command (cause)
  - object - wire,transmission (contributing factor)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

The airplane impacted a muddy field after maneuvering to avoid power lines.  The pilot reported that on his first run he had 200 gallons of chemicals and 60 gallons of fuel.  The pilot reported, "I took off from the airport and went around town.  When I was com[m]ing up to a set of power lines I hit an air pocket and didn't have enough altitude to clear the lines so I turned to the east and hit the ground."  The pilot reported the airplane did not have a mechanical malfunction.
