## Probable cause

The flight instructor's delayed remedial action during the landing roll in response to the student's loss of directional control, which resulted in a ground loop.  A factor associated with the accident was the student's failure to maintain directional control.

## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, dual student (contributing factor)
  - remedial action - delayed, pilot in command(cfi) (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ground

## Analysis

During the initial tailwheel and refresher flight training, the left seat owner/pilot lost control of the airplane on the landing roll.  The subsequent delayed remedial action by the right seat instructor pilot resulted in the airplane ground looping, causing substantial damage to the airplane.
