From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

While aircraft was passing through 18,000 feet, both generators failed and would not reset. Battery power rapidly deteriorated and the crew declared an emergency and diverted to kefd. During the descent total electrical failure occurred. After the aircraft exited the overcast layer the emergency gear extension checklist was completed, the status of the gear was unknown to the pilots due to the electrical failure. The aircraft landed at kefd on the main gear and nose of the aircraft and came to rest approximately 1200 feet down the runway.
