Analysis
The pilot and his passenger were performing a local flight after the installation of a new GPS system. After flying for about 15 minutes, the pilot lowered the landing gear in preparation to land. The pilot observed the landing gear in an extended position via landing gear mirrors and confirmed a cockpit gear down light indication. After touchdown, the main landing gear collapsed. The airplane skidded and came to rest upright on an adjacent taxiway. The airplane sustained substantial damage to the left horizontal stabilizer and left elevator. Postaccident examination of the landing gear system revealed no anomalies that would have precluded normal operation. During the examination, 10 landing gear extensions and retractions were performed without any anomalies noted with the system. The cockpit landing gear light indications functioned during each gear cycle, and no leaks in the system were detected. The reason for the main landing gear collapse could not be determined.
