## Probable cause

the pilot failed to maintain clearance from the corn crop.  Additional factors were the inoperative spray pump,  the corn crop, and the pilot's diverted attention.

## 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
  - terrain condition - crop (contributing factor)
  - altitude/clearance - not maintained, pilot in command (cause)
  - diverted attention, pilot in command (contributing factor)
  - spray/dusting equipment - inoperative (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

The airplane sustained substantial damage when it impacted the ground while spraying a field of corn.  The pilot reported, "Upon arrival at the field, it became evident my spray pump was inoperative.  My attention was diverted for a moment as I was trying to solve the problem, and my wheels got in the crop.  I was unable to recover.  The terrain was a flat cornfield and the wreckage was all intact in one spot."
