## Sequence of events

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

- Complete gear collapsed, landing - flare/touchdown
  - landing gear,gear switch - incorrect (cause)
  - landing gear,gear switch - loose (cause)
  - maintenance,installation - improper, other maintenance personnel (cause)
  - wheels up landing - inadvertent, pilot in command

## Analysis

PILOT STATED HE HAD 3 GREEN GEAR LIGHTS. DURING TOUCHDOWN AND ROLL THE LANDING GEAR COLLAPSED. THE LANDING GEAR CONTROL SWITCH COLLAR WAS DEFECTIVE AND IF THE PILOT DID NOT HOLD THE GEAR SELECTOR IN THE DOWN POSITION IT MAY HAVE RETURNED TO OFF BEFORE THE GEAR WAS LOCKED DOWN. THIS WOULD ACCOUNT FOR THE GEAR COLLAPSING UNDER THE WEIGHT OF LANDING. IT WAS NOT DETERMINED HOW LONG THIS SITUATION HAD EXISTED. IN ADDITION, IT APPEARED THAT THE SWITCH MAY HAVE BEEN INSTALLED UPSIDE DOWN REQUIRING THE HANDLE TO BE PULLED OUT TO GET THE GEAR IN THE DOWN POSITION.
