Aviation safety reports, made easier to study

NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.

The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.

The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

The pilot reported that, during the takeoff roll on a plowed, snow-covered runway, he could "feel the [airplane] pulling to the right" and corrected with opposite rudder, but the airplane slowly exited the runway to the right and impacted a snowbank. The airplane sustained substantial damage to both propellers and the right engine mount. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The airport's automated weather observation station reported that, about 5 minutes before the accident, the wind was from 110° at 5 knots, 1 1/4 statute miles visibility, overcast at 900 ft, temperature 18°F, dew point 12°F, and light snow. The airplane departed from runway 36.

NTSB Probable Cause

The pilot's failure to maintain to directional control during takeoff from a snow-covered runway with a right, quartering tailwind, which resulted in a runway excursion and impact with a snowbank.

The pilot reported that, during the takeoff roll on a plowed, snow-covered runway for an instrument flight, he could "feel the [airplane] pulling to the right" and corrected with opposite rudder but the airplane slowly exited the runway to the right and impacted a snowbank. The twin-engine airplane sustained substantial damage to both propellers and the right engine mount. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation station located on the airport reported that, about 5 minutes before the accident, the wind was from 110° at 5 knots, 1 1/4 statute mile visibility, overcast at 900 ft, temperature 18°F, dew point 12°F, and light snow.
