## Probable cause

IMPROPER USE OF THE BRAKES BY THE PILOT.  THE CROSSWIND AND THE PILOT'S FAILURE TO MAINTAIN RUNWAY ALIGNMENT WERE CONTRIBUTING FACTORS.

## Sequence of events

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

- Nose over, landing - roll
  - weather condition - crosswind (contributing factor)
  - proper alignment - not maintained, pilot in command (contributing factor)
  - brakes(normal) - improper use of, pilot in command (cause)

## Analysis

THE PILOT WAS LANDING ON RUNWAY 32L WITH THE WIND FROM 360 DEGREES AT 6 KTS. DURING THE TOUCHDOWN PHASE, THE AIRCRAFT BEGAN ANGLING OFF THE SIDE OF THE RUNWAY. TO KEEP THE AIRCRAFT FROM DEPARTING THE RUNWAY, THE PILOT APPLIED BRAKES, BUT THE AIRCRAFT NOSED OVER.
