NTSB narrative
THE PLT REPORTED THAT AFTER THE NOSEWHEEL TOUCHED DOWN, IT BEGAN A VIOLENT & UNCONTROLLABLE OSCILLATION, THEN LOCKED APRX 25 DEG TO THE LEFT. THE ACFT VEERED OFF THE LEFT SIDE OF THE RUNWAY, CROSSED AN AREA OF SOFT GROUND AND ANGLED ACROSS A TAXIWAY. AFTER CROSSING THE TAXIWAY, IT ENTERED ANOTHER AREA OF SOFT DIRT WHERE THE NOSE GEAR SEPARATED. AFTER COMING TO REST, THE PROPELLERS DUG HOLES IN THE SOFT GROUND BEFORE THE ENGINES WERE SHUT DOWN. AN INVESTIGATION REVEALED THE TIRES LEFT BLACK SCRUB MARKS (800 FT LONG) BEFORE THE ACFT DEPARTED THE RUNWAY. LOW AIR PRESSURE WAS FOUND IN THE NOSE GEAR STRUT AND SHIMMY DAMPER. ACCORDING TO A REPRESENTATIVE FROM THE MANUFACTURER, THIS LOW PRESSURE COULD CAUSE THE NOSE GEAR TO SHIMMY. PROPELLER STRIKE MARKS IN THE FIRST AREA OF SOFT GROUND INDICATED THE GROUND SPEED WAS 82 KTS WHERE THEY FIRST CONTACTED THE GROUND.

- 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.
