Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary

First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary

Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary

NTSB narrative

The noninstrument-rated private pilot and two passengers were on a cross country flight on top of an overcast at 10,000 feet msl when the pilot radioed FAA air traffic controllers for assistance. The pilot told controllers he thought he was a few miles from Anchorage, Alaska, his intended destination, but he was actually about 124 miles northwest of Anchorage. The pilot was asked if he could turn towards and cross a nearby mountain range to reach VFR conditions. He indicated he did not have enough fuel left, and that he was presently flying through the tops of the overcast. During his communications with the controllers, the pilot noted a marked disparity between his wet compass and his gyro driven heading indicator; he also said his only electronic navigation instrument aboard, a loran, was not reliable. Radio contact was lost with the pilot, and soon thereafter, an ELT was heard. The airplane was discovered crashed in a near vertical position on a glacier. Postaccident inspection disclosed no mechanical anomalies with the airplane and a functional loran. About five to six gallons of fuel was remaining in the left wing fuel tank.

Probable cause

The pilot's continued VFR flight into instrument meteorological conditions, and subsequent failure to maintain control of the airplane. Factors associated with the accident are the pilot's inadequate weather evaluation, his becoming lost/disoriented, and spatial disorientation.

  • 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: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
