## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - flare - improper, copilot/second pilot (cause)
- Main gear collapsed, landing - roll
  - landing gear,gear locking mechanism - overload

## Analysis

AS THERE WERE NO PASSENGERS ON THE FLIGHT, THE COPILOT WAS FLYING THE LEG FROM THE LEFT SEAT. ON ARRIVAL OVER CLARKSVILLE, THE CAPTAIN INSTRUCTED THE FIRST OFFICER TO EXECUTE A SHORT FIELD LANDING. THE APPROACH WAS NORMAL UNTIL THE AIRCRAFT WAS FLARED HIGH AND CONSEQUENTLY LANDED HARD. DURING ROLL OUT THE RIGHT MAIN GEAR COLLAPSED INTO THE WHEEL WELL AND THE RIGHT WING AND PROPELLER SETTLED ONTO THE RUNWAY. INVESTIGATION REVEALED THAT THE RIGHT MAIN GEAR LOCK LINK WAS FRACTURED IN THREE PLACES. A METALLURGICAL EXAMINATION OF THE FRACTURES INDICATED THAT THEY HAD OCCURRED IN OVERLOAD.
