AFTER WHAT THE PILOT DESCRIBED AS A NORMAL LANDING HIS SEAT DISLODGED FROM THE TRACK AND TILTED BACK AGAINST THE REAR SEAT. HE HELD ON TO THE YORE BUT WAS UNABLE TO REACH THE PEDALS. THE A/C SLOWED TO ABOUT 20-25 MPH THEN THE RIGHT MAIN LANDING GEAR FAILED AT THE ATTACHING POINT. LATER INSPECTION REVEALED THAT CORROSION WAS FOUND IN THE AREA OF THE FAILURE. THE A/C HAD BEEN THROUGH AN ANNUAL INSPECTION IN MARCH, JUST FIVE MONTHS PRIOR TO THE ACCIDENT.
