## Analysis

FOLLOWING ONE HOUR OF AIRWORK THE INSTRUCTOR AND STUDENT RETURNED TO THE AIRPORT FOR A SHORT FIELD LANDING. THE INSTRUCTOR STATED THAT THE STUDENT LOWERED THE GEAR ON DOWNWIND. HE STATED FURTHER THAT THEY BOTH CHECKED THE GEAR POSITION INDICATOR ON BASE LEG AND FINAL APPROACH AND THE INDICATOR SHOWED GEAR DOWN BOTH TIMES. DURING THE FLARE THE GEAR WARNING HORN SOUNDED AND THE INSTRUCTOR NOW SAW THAT THE GEAR INDICATOR NOW SHOWED GEAR UP. POWER WAS ADVANCED BUT THE AIRCRFT SETTLED TO THE RUNWAY AND STOPPED STRAIGHT AHEAD. THE GEAR COMPONENTS WERE EXAMINED FOLLOWING THE ACCIDENT AND NO MALFUNCTIONS COULD BE FOUND.
