NTSB narrative
The certificated private pilot departed a rural airport in Alaska on a VFR cross country flight along remote, coastal terrain, without filing a flight plan. Ten days later, the airplane was reported overdue when it did not arrive at a possible intermediate stop in the Seattle, Washington, area, or at the pilot's planned destination in Michigan. After the overdue report, Coast Guard personnel in Alaska began to gather data about the airplane, pilot, and possible routes. They were not aware that a wing mounted auxiliary fuel tank had been found the day after the airplane departed, in the Port Angeles, Washington, area. On the day the fuel tank was found, Coast Guard personnel from Port Angeles conducted a search for other debris, but found none. Since the pilot did not file a flight plan, Coast Guard and FAA personnel in the Seattle area did not have any reports of overdue airplanes. After the airplane was reported overdue, FAA personnel in Alaska recalled a report of the fuel tank being found in the Seattle area. The missing airplane report, and the fuel tank, were eventually linked together. Family members positively identified the fuel tank as part of the accident airplane. The pilot is presumed to have received fatal injuries. After an additional search, no other parts of the airplane have been located. Weather data in the Port Angeles area on the presumed day of the accident, included a wide area of rain showers.

- 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 1998-10-04.
