NTSB narrative
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 about 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.
Probable cause
The pilot's failure to maintain visual contact with the taxiway. Factors were the pilot's disabling the electrical system by turning off the master switch, a dark night, and excessive taxi speed.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1998-05-18.
