## Sequence of events

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

- Main gear collapsed, landing - flare/touchdown
  - landing gear,main gear - jammed (cause)
  - directional control - not possible, pilot in command (contributing factor)
  - landing gear,gear warning system - failure,total (cause)
  - ground loop/swerve - uncontrolled, pilot in command (contributing factor)
  - landing gear,gear indicating system - failure,total (cause)

## Analysis

THE ACFT LANDED WITH ITS LEFT MAIN GEAR JAMMED IN THE UP POSITION. SINCE THE LANDING GEAR WARNING AND INDICATING SYSTEM INDICATED ALL NORMAL THE CREW WAS UNAWARE OF THE PROBLEM UNTIL THE ROLL OUT. INVESTIGATION REVEALED THAT THE LEFT MAIN GEAR ACTUATING MOTOR CONTINUED TO OPERATE EXTENDING THE NOSE GEAR AND RIGHT LANDING GEAR TO THE DOWN POSITION. THE LEFT MAIN GEAR ACTUATING ROD FAILED FROM FORCES INDUCED BY THE LANDING GEAR ACTUATING MOTOR TRIGGERING THE FALSE INDICATION OF THE GREEN GEAR LIGHT WHICH IS ACTIVATED BY A MICRO-SWITCH ON THE MOTOR.
