## Sequence of events

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

- Airframe/component/system failure/malfunction, descent - normal
  - landing gear,main gear - movement restricted (cause)
  - maintenance,adjustment - improper, company maintenance personnel (cause)
  - emergency procedure - attempted, pilot in command (contributing factor)
  - landing gear,emergency extension assembly - inoperative (contributing factor)
- Main gear collapsed, landing - roll

## Analysis

ARRIVING OVER HIS DESTINATION AIRPORT, THE PILOT SAID HE HAD AN UNSAFE RIGHT MAIN GEAR LIGHT INDICATION. AFTER CIRCLING ABOUT TWO HOURS TO LIGHTEN THE FUEL LOAD, AND ATTEMPTING TO LOWER THE GEAR BY EMERGENCY PROCEDURES, A LANDING WAS ATTEMPTED. AFTER TOUCHDOWN AND DURING THE ROLL OUT, THE RIGHT GEAR COLLAPSED ABOUT 3/4 DOWN THE RUNWAY, CAUSING THE ACFT TO VEER OFF THE RUNWAY AND SUSTAIN SUBSTANTIAL DAMAGE. POST ACCIDENT INVESTIGATION REVEALED POOR RIGGING OF THE GEAR RETRACTION SYSTEM.
