## Probable cause

A BLOWN TIRE AND BOTH PILOTS' FAILURE TO MAINTAIN DIRECTIONAL CONTROL.

## Sequence of events

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

- Airframe/component/system failure/malfunction, landing - flare/touchdown
  - landing gear,tire - burst (cause)
- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, check pilot (cause)
  - directional control - not maintained, pilot in command (cause)
- On ground/water collision with object, landing - roll
  - object - sign
- Main gear collapsed, landing - roll

## Analysis

THE PRIVATE PILOT AND THE INSTRUCTOR PILOT HAD BEEN PRACTICING VARIOUS TYPES OF TAKEOFFS AND LANDINGS.  UPON TOUCHDOWN, THE AIRPLANE VEERED TO THE RIGHT AND DEPARTED THE RUNWAY.  THE RIGHT WING DROPPED AND THE PROPELLER STRUCK THE GROUND.  THE AIRPLANE THEN COLLIDED WITH A TAXIWAY SIGN AND THE RIGHT MAIN LANDING GEAR COLLAPSED.  POSTACCIDENT EXAMINATION DISCLOSED THE RIGHT MAIN TIRE HAD BLOWN.
