NTSB narrative
THE AIRCRAFT WAS BEING REPOSITIONED FOR AN AIR TAXI OPERATION. THE PILOT BEGAN TAKING OFF ON A SLUSH COVERED RUNWAY. HE REPORTED THAT AS THE AIRCRAFT ACCELERATED, THE NOSEWHEEL BEGAN TO SLING WATER AND SLUSH OFF THE RUNWAY AND ONTO THE WINDSHIELD. HE RAISED THE NOSEWHEEL SLIGHTLY TO ELIMINATE THIS DISTRACTION. AT ABOUT THAT POINT, THE AIRCRAFT SWERVED TO THE RIGHT. REPORTEDLY, THE PILOT IMMEDIATELY MOVED BOTH POWER LEVERS BACK TO THE REVERSE TO ABORT. THE AIRCRAFT THEN SWERVED ABRUPTLY TO THE LEFT, BUT CONTINUED OFF THE RIGHT SIDE OF THE RUNWAY AND WENT DOWN AN EMBANKMENT. THE PILOT BROUGHT BOTH CONDITION LEVERS BACK TO THE EMERGENCY SHUT-OFF POSITION AS THE PLANE SKIDDED OFF THE RUNWAY. FROZEN SLUSH WAS FOUND ON THE AIRFRAME. A GRAYISH-WHITE RESIDUE, POSSIBLY FROM EVAPORATED WATER/STEAM WAS NOTED INSIDE THE EXHAUST STACK OF THE RIGHT ENG. BOTH PROP FEATHER VLVS WERE FOUND OPEN, BOTH ENG SHUT- OFF VLVS WERE CLOSED, BOTH PROP LATCH PINS WERE ENGAGED, BUT THE LEFT PROP WAS FEATHERED & THE RIGHT WAS IN FLAT PITCH.

- 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.
