- Complete gear collapsed, landing - roll
  - landing gear - undetermined (cause)

## Analysis

THE PLT RPRTD THAT AFTER TAKEOFF, THE LANDING GEAR DID NOT RETRACT. HE ATTEMPTED TO RECYCLE IT SVRL TIMES, THEN AFTER TURNING OFF THE 'PANEL LIGHTS,'  THE LANDING GEAR INDCR (DOWN & LOCKED LIGHT) ILLUMINATED.  HE FLEW BY THE TOWER FOR VISUAL CONFIRMATION THAT THE GEAR WAS DOWN.  AFTER BEING ADVISED THAT IT WAS, HE RETURNED FOR LANDING. HE RPRTD THAT AFTER REDUCING POWER TO LAND WITH NO WARNING HORN, THE AIRPLANE TOUCHED DOWN.  DURING THE LANDING ROLL, THE GEAR COLLAPSED.  NO REASON WAS FOUND FOR THE GEAR TO COLLAPSE.  THE OWNER'S HANDBOOK NOTED THAT THE LANDING GEAR INDCR LIGHTS WOULD DIM WHEN THE NAV LIGHTS WERE ON.
