Analysis

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.
