## Probable cause

The failure of the student to maintain directional control during landing and the flight instructor's inadequate supervision of the flight.

## 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 (cause)
  - supervision - inadequate, pilot in command(cfi) (cause)
  - ground loop/swerve - encountered
- Main gear collapsed, landing - roll
  - terrain condition - runway

## Analysis

The pilot was receiving dual instruction from the flight instructor for the purpose of receiving a tail wheel endorsement. He had accumulated a total of 7 hours tail wheel instruction in the accident airplane. The flight instructor reported that during the landing roll, the airplane yawed to the right and entered a ground loop which collapsed the left main landing gear.
