NTSB narrative

The pilot departed on an instrument flight plan on a route where mountain obscuration, clouds, precipitation, and possible icing conditions had been forecast. Although the pilot had been cleared to 12,000 feet, he reported that he was having trouble climbing above 11,000 feet. Soon thereafter he reported that he was reversing course and returning to the airport of departure. Although the air traffic controller told him he could not clear him below 11,000 feet, the pilot reported that the aircraft was continuing to descend. The last clearly audible report from the pilot was that he was down to 8,800 feet, and another pilot in the area reported that he thought he heard the pilot say he had descended to 6,200 feet. Soon thereafter the aircraft impacted the mountainous terrain in an area where other aircraft were then reporting airframe icing conditions.

Probable cause

The pilot's failure to maintain clearance from the terrain while attempting to maneuver back to the departure airport after encountering icing conditions. Factors include icing conditions, mountainous terrain, and low ceilings.

  • 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, coordinates. 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.
