## Probable cause

A HARD LANDING THAT COLLAPSED THE LEFT MAIN GEAR DUE TO OVERLOAD FAILURE OF THE TRUNION.

## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - flare - improper, pilot in command (cause)
- Gear collapsed, landing - flare/touchdown

## Analysis

THE PILOT WAS LANDING ON RUNWAY 33. A WITNESSS STATED THAT THE PILOT 'CLEARED THE TREES AT THE APPROACH END OF THE RUNWAY. AT THIS POINT, [THE AIRPLANE] APPEARED TO DEVELOP A HIGH SINK RATE AND TO DROP THE LAST 10-15 FEET TO THE RUNWAY, HITTING HARD SHORT OF THE DISPLACED THRESHOLD. THE LEFT MAIN GEAR COLLAPSED FIRST, FOLLOWED BY THE REST OF THE GEAR.'
