## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

THE PILOT STATED THAT HE HAD PERFORMED SEVERAL TAKEOFFS AND LANDINGS ON ICE COVERED LAKE WINNEBAGO.  WHILE TAXIING AT APPROXIMATELY 15 MPH AFTER THE LAST LANDING, THE LEFT LANDING GEAR FOLDED UP UNDERNEATH THE FUSELAGE.  THE LEFT WING AND PROPELLER THEN CONTACTED THE ICE AS THE AIRCRAFT CAME TO A STOP.

THE INVESTIGATION DETERMINED THAT THE LEFT LANDING GEAR SUSTAINED SUBSTANTIAL DAMAGE.  THE LANDING GEAR FAILED DUE TO THE FAILURE OF THE LEFT MAIN LANDING GEAR FRONT ATTACHMENT CLUSTER.  THERE WAS ALSO SUBSTANTIAL DAMAGE TO THE LEFT WING DUE TO A CRACKED WING SPAR.  THE PROPELLER SUSTAINED MINOR DAMAGE.

## The NTSB's investigation of this event (1)
