## Sequence of events

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

- Main gear collapsed, landing - roll
  - landing gear,main gear strut - fatigue (cause)
- Loss of control - on ground/water, landing
  - directional control - not maintained
  - ground loop/swerve - uncontrolled

## Analysis

THE PLT RPRTD THAT SHORTLY AFTER TOUCHDOWN, THE ACFT STARTED TO TRACK TO THE LEFT SIDE OF THE RWY. HE STATED THAT HE APPLIED RIGHT RUDDER & BRAKE, BUT THIS HAD NO EFFECT, SO HE INCREASED POWER. SUBSEQUENTLY, THE RIGHT WING DROPPED, THE PROP HIT THE RWY & THE ACFT CONTD OFF THE LEFT SIDE INTO GRASS. AFTER THE ACDNT, THE WHEEL & PART OF THE STRUT FROM THE RIGHT MAIN GEAR WERE FOUND IN THE CENTER OF THE RWY. THE OWNER SAID THE STRUT FAILED THRU A BOLT HOLE & THE FRACTURE WAS CRYSTALLIZED.
