## Sequence of events

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

- Loss of control - on ground/water, takeoff - roll/run
  - landing gear,tire - pressure too low (contributing factor)
  - preflight planning/preparation - inadequate, pilot in command (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - not corrected, pilot in command (cause)
  - total, pilot in command (cause)
- Nose over, takeoff - roll/run
  - aborted takeoff - not performed, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)

## Analysis

DIRECTIONAL CONTROL WAS LOST DURING TAKEOFF ROLL DUE TO A FLAT NOSE WHEEL TIRE. THE AIRCRAFT CONTINUED TO VEER TO THE LEFT OF THE RUNWAY DESPITE THE STUDENT PILOTS ATTEMPTS TO CORRECT TO THE RIGHT. THE AIRCRAFT DEPARTED THE RUNWAY WHERE IT NOSED OVER.
