## Probable cause

LANDING GEAR TIRE FAILURE AND DIRECTIONAL CONTROL NOT MAINTAINED BY THE PIC/CFI.

## Sequence of events

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

- Airframe/component/system failure/malfunction, landing - roll
  - landing gear,tire - failure,total (cause)
- Loss of control - on ground/water, landing - roll
- Nose over, landing - roll

## Analysis

DURING A DUAL INSTRUCTIONAL FLIGHT, DIRECTIONAL CONTROL WAS LOST DURING THE ROLL-OUT, AND THE ACFT VEERED OFF THE RUNWAY AND NOSED OVER. POST ACCIDENT INVESTIGATION REVEALED THE RIGHT MAIN GEAR TIRE TO BE FLAT.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
