## 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 - overload
  - unsuitable terrain or takeoff/landing/taxi area - selected, pilot in command (cause)

## Analysis

WHILE THE PILOT WAS LANDING ON A ROAD, THE LEFT MAIN GEAR, FORWARD SUPPORT TUBE FAILED. THE PILOT STATED THAT HE APPLIED TAKEOFF POWER TO AVOID GROUND LOOPING AND THE PLANE BECAME AIRBORNE. HE STATED THAT HE "DUMPED" HIS FLAPS WHILE INDICATING 60 MPH AND STARTED TO MAKE A SHALLOW TURN TOWARD HILLS AWAY FROM THE VILLAGE. HE BELIEVED THE AIRCRAFT ENCOUNTERED A LIGHT DOWNDRAFT OR SHEAR AND STALLED. AN EXAMINATION OF THE FAILED SUPPORT TUBE REVEALED THAT IT HAD FAILED FROM OVERLOAD. REPORTEDLY, THERE WAS COMPACTED SNOW AND ICE ON THE INTENDED SURFACE.
