NTSB narrative
THE RUNWAY SURFACE HAD BEEN GRADED, AND SOFT GRADED MATERIAL HAD BEEN PUSHED INTO A SMALL DEPRESSION ADJACENT TO THE RUNWAY. THE AIRPLANE WAS TAXIING BACK TO THE RAMP, WHEN THE NOSE WHEEL ROLLED INTO THE DEPRESSION AND THE NOSE GEAR COLLAPSED. THE SOFT AREA/DEPRESSION HAD BEEN PREVIOUSLY MARKED WITH YELLOW CONES. THE CONES HAD BEEN REMOVED WHILE THE RUNWAY WAS BEING GRADED AND HAD NOT BEEN REPLACED. NO NOTAMS HAD BEEN ISSUED. THE ALASKA SUPPLEMENT STATED THAT THE RUNWAY WAS SOFT AND RUNWAY CONDITIONS WERE NOT MONITORED.
Probable cause
THE AIRPORT MAINTENANCE PERSONNEL'S INADEQUATE MAINTENANCE OF THE RUNWAY BY NOT REPLACING THE YELLOW CONES THAT MARKED THE SOFT AREA. THE SOFT AREA ON THE RUNWAY WAS A RELATED FACTOR.

- 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.
