NTSB narrative
The pilot said that the icing conditions obscured the view through the windshield even with the application of anti-icing fluid. In his written report, he said that the approach lights came on and that the runway lights did not. He said that he had no visual reference to the runway during the landing flare. He reported that the airplane landed on the runway, but struck a snowbank on the north side of the runway. The airport lighting system has two receivers on the pilot controlled frequency 118.9. One receiver controls the approach lights and the other controls the runway and taxiway lights. Because the approach lights receiver is located close to the approach, it has better reception than the runway lights receiver does.
Probable cause
the pilot not obtaining proper runway centerline alignment during landing. Associated factors were the pilot's obscured view through the iced windshield, the runway lights not activating simultaneously with the approach lights, incomplete visual detection of the runway environment and no notice to airmen of the reduced reception of the runway light receiver.

- 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 1999-02-06.
