## Probable cause

EXCESSIVE BRAKING BY THE DUAL STUDENT.

## 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
  - weather condition - crosswind
  - directional control - not maintained, dual student
  - remedial action - delayed, pilot in command(cfi) (contributing factor)
- Nose over, landing - roll
  - brakes(normal) - excessive, dual student (cause)

## Analysis

THE PRIVATE PILOT WAS PRACTICING TAKEOFFS AND LANDINGS WITH AN INSTRUCTOR TO OBTAIN AN ENDORSEMENT FOR TAILWHEEL AIRPLANES. THE WIND WAS 70 DEGREES LEFT OF RUNWAY HEADING AT 16 KNOTS. DURING LANDING ROLLOUT, THE AIRPLANE TURNED INTO THE WIND. THE INSTRUCTOR CAME ON THE CONTROLS TO REGAIN DIRECTIONAL CONTROL. THE DUAL STUDENT APPLIED BRAKES, AND THE AIRPLANE NOSED OVER.
