## Probable cause

THE PILOT FAILED TO MAINTAIN CONTROL OF THE AIRCRAFT.  A FACTOR WAS: IMPROPER SUPERVISION BY THE FLIGHT INSTRUCTOR.

## Sequence of events

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

- Loss of control - on ground/water, landing - flare/touchdown
  - aircraft control - not maintained, dual student (cause)
  - supervision - inadequate, pilot in command(cfi) (contributing factor)

## Analysis

WHILE THE CERTIFIED FLIGHT INSTRUCTOR WAS GIVING A COMMERCIAL PILOT A TAIL WHEEL CHECKOUT, THE AIRCRAFT OVERSHOT FINAL DURING A TOUCH-AND-GO LANDING. THE STUDENT WAS SLIPPING THE AIRCRAFT BACK TO LINE UP WHEN THE TAIL WHEEL CONTACTED THE GROUND.  CONTROL WAS LOST AND THE AIRCRAFT FLIPPED OVER.
