## Probable cause

EXCESSIVE APPLICATION OF THE BRAKES DURING LANDING ROLL.

## Sequence of events

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

- Nose over, landing - roll
  - brakes(normal) - excessive, pilot in command (cause)
  - lack of total experience in type of aircraft, pilot in command (contributing factor)

## Analysis

THE PRIVATE PILOT WAS GETTING A CHECK OUT IN TAIL WHEEL AIRCRAFT.  EARLIER IN THE DAY, THE PILOT AND AN INSTRUCTOR HAD PERFORMED SIX STOP AND GO LANDINGS.  THIS FLIGHT WAS THE PILOT'S FIRST OBSERVED SOLO.  DURING LANDING ROLL HE APPLIED EXCESSIVE BRAKING AND THE AIRCRAFT NOSED OVER.
