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.

(-23) PIC preflighted aircraft noting the battery was in a low state of charge. PIC used ground start unit to start aircraft and performed normal after start checks. Aircraft departed mob for fuel stop at 1R8. In final approach PIC selected landing gear to down position and lost electrical power. PIC cycled both alternator(s) and battery switchces but failed to regain electrical power. PIC aborted landing at 1R8 and elected to return to mob. On approach to mob PIC manually lowered the landing gear until he felt resistance in the gear handle. PIC requested fly by of mob tower to confirm landing gear was down. Mob confirmed landing gear looked fully down. PIC landed on runway 18 and during roll out both main landing gear began folding under the aircraft. Aircraft came to a stop on the runway with main landing gear partially folded up and nose gear fully down. Aircraft was resting on it's tail and sustained only minor damage to the tail cone area. Postflight evaluation revealed headset communication cable wrapped around manual landing gear extension handle preventing damage to the tail cone area. Post flight evaluation revealed headset communication cable wrapped around manual landing gear extension handle preventing full extension of landing gear. Post incident operation of landing gear revealed manual extension handle lacked nine turns to full down and locked position.
