Narrative:
The pilot was executing a full-stop landing, prior to which he had confirmed the illumination of the three green "gear-down" lights. Although the touchdown was uneventful, during the landing roll the right main landing gear actuator shaft retracted into its housing, resulting in the retraction of the right main landing gear into its wheel well. The airplane then departed the runway and impacted the adjacent runway lights. A series of postaccident inspections and tests were unable to determine what anomaly or malfunction initiated the retraction of the actuator shaft.

Probable Cause: The uncommanded retraction of the right main landing gear hydraulic actuator strut for undetermined reasons.
