Incident Overview
A pilot reported that they decided to terminate their flight and land at Dacy Airport in Harvard, Illinois, due to deteriorating visibility and an inability to communicate with Air Traffic Control. During the landing rollout, the main landing gear collapsed, resulting in substantial damage to the aircraft.
Radio and Electrical Issues
The pilot stated that the panel-mounted radio displays went blank during the flight, although the charge indicator showed a normal charge rate. The pilot lowered the landing gear and observed that the gear down indicator light "appeared to be green."
Landing Gear System
The aircraft's landing gear operation is accomplished by hydraulic actuators powered by an electrically-driven hydraulic power pack. The aircraft is also equipped with an emergency gear extension hand pump for manual deployment.
Post-Incident Examination
A representative of the maintenance facility that performed the repairs to the aircraft stated that the landing gear system was examined, and no defects were found. The checks included the normal retraction system, the emergency retraction system, and the position indicating system. The representative also noted that the charging system was not operating when the aircraft was recovered, and the alternator was replaced during the subsequent repairs.
