## Probable cause

THE PILOT'S DELAY IN INITIATING A GO-AROUND, AND HIS FAILURE TO MAINTAIN PROPER RUNWAY ALIGNMENT.  FACTORS RELATED TO THE ACCIDENT WERE:  FAILURE OF THE PILOT TO ATTAIN THE PROPER TOUCHDOWN POINT AND THE CROP.

## Sequence of events

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

- In flight collision with terrain/water, go-around (vfr)
  - proper touchdown point - not attained, pilot in command (contributing factor)
  - go-around - delayed, pilot in command (cause)
  - terrain condition - crop (contributing factor)
  - proper alignment - not maintained, pilot in command (cause)

## Analysis

DURING A TOUCH-&-GO LANDING, THE STUDENT PLT INITIATED A GO-AROUND.  HE SAID THAT HE FELT THAT THE ACFT WAS TOO FAR DOWN THE RWY & THAT HE PULLED BACK ON THE YOKE TOO MUCH & STALLED THE ACFT.  THE ACFT DRIFTED LEFT.  SUBSEQUENTLY, THE LEFT WING CONTACTED TALL CORN & THE ACFT CAME TO REST IN THE CORN FIELD.
