NTSB narrative
The aircraft sustained substantial damage when the main landing gear collapsed on landing rollout. The pilot reported that he decided to terminate the flight and land at Dacy Airport in Harvard, Illinois due to deteriorating visibility and the inability to communicate with Air Traffic Control. He said that the panel mounted radio displays went blank but the charge indicator indicated a normal charge rate. The pilot reported that he lowered the landing gear and that the gear down indicator light, "...appeared to be green." The main landing gear collapsed during the landing. The airplane landing gear operation is accomplised by hydraulic actuators powered by an electrically-driven hydraulic power pack. An emergency gear extension hand pump is used for emergency landing gear extension. A representative of the maintenance facility that performed the repairs to the airplane 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. He stated that the charging system was not operating when the airplane was recovered. He said that the alternator was replaced during the repairs to the airplane.
Probable cause
The pilot's failure to verify the extension of the landing gear. Factors were the alternator failure, and the main landing gear down locks not engaged.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
