In flight collision with terrain/water
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
Visual flight rules (VFR) flight into instrument meteorological conditions (IMC)
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

TWO AIRPLANES DEPARTED SEWARD WITHIN MINUTES OF EACH OTHER ON A LOCAL FLIGHTSEEING TRIP, AND THEIR FLIGHT ROUTES WERE TO BE THE SAME. AFTER REACHING AIALAK BAY, THIS AIRPLANE PASSED THE OTHER AND STARTED THE RETURN TRIP TO SEWARD. THE PASS THEY WOULD NORMALLY USE WAS OBSCURED BY CLOUDS. THE PENINSULA THAT SEPARATED AIALAK BAY AND SEWARD WAS THE ONLY PART OF LAND THAT WAS OBSCURED BY WEATHER. THE BASES OF THE CLOUDS WERE AT 1200 FEET MSL. THE AIRPLANE WAS LOCATED ON THE NORTHEAST SIDE, AT THE 2700 FOOT LEVEL OF A MOUNTAIN, AND THE WRECKAGE WAS SCATTERED ALONG 330 DEGREES. THE PILOT HAD BEEN HIRED LESS THAN 2 MONTHS BEFORE THE ACCIDENT AS A GROUND HANDLER AND FUELER, AND FOR PILOT TRAINING. TWO DAYS BEFORE THE ACCIDENT HE WAS AUTHORIZED TO FLY PART 135 FLIGHTSEEING TRIPS.

Probable cause

THE PILOT-IN-COMMAND'S ATTEMPT TO FLY UNDER VISUAL FLIGHT RULES WHILE IN INSTRUMENT METEOROLOGICAL CONDITIONS. CONTRIBUTING FACTORS TO THE ACCIDENT WERE THE LOW CEILING AND SURROUNDING MOUNTAINOUS TERRAIN.

  • 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.
