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.

Went off taxiway at night and down an embankment. Had lost electrical power. Unable see taxiway line. (.4)the pilot said that he experienced a total electrical failure while on a night cross-country flight. He landed without incident but while taxiing along the unlit taxiway, he lost sight of the centerline stripe. The airplane went off the taxiway and down an embankment. The airport night manager said the pilot told him he would 'turn on the navigation lights, if necessary,' to warn other airplanes. Postaccident inspection disclosed that when the master switch was turned on, all electrical components functioned normally. A specific gravity check indicated the battery was fully charged. According to the operator's records, the hobbs meter and tachometer registered 65.9 and 3903.3, respectively, when the pilot checked the airplane out. At the accident site, the hobbs meter and tachometer registered 67.6 and 3905.1, respectively, a hobbs meter difference of 1.7 hours and a tachometer difference of 1.8 hours. The operator said he believed the pilot had turned off the master switch in an attempt to save on rental charges. He had also received reports from other renter pilots who said the pilot had bragged abput saving money by turning off the master switch. An FAA inspector said that, based on the point where the aircraft departed the taxiway and its point of impact, taxi speed was excessive.

A VFR flight plan had been filed and visual meteorological conditions existed at the time. According to the pilot, it was a dark night and the aircraft experienced a total electrical failure while in level cruise flight.
