## Sequence of events

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

- Hard landing, landing
  - flare - improper, pilot in command (cause)

  - stolen aircraft/unauthorized use - intentional, pilot in command (contributing factor)

## Analysis

THE PRE-SOLO STUDENT PILOT HAD TAKEN THE AIRCRAFT WITHOUT THE OWNER'S PERMISSION. HE FLEW AROUND THE AREA FOR APPROXIMATELY 30 MINUTES BEFORE RETURNING TO THE AIRPORT. AFTER A HARD LANDING, THE NOSE WHEEL TIRE BLEW CAUSING THE NOSE WHEEL TO COLLAPSE. THE AIRCRAFT RECEIVED SUBSTANTIAL DAMAGE TO THE FIREWALL AND FUSELAGE.
