NTSB narrative

The certificated airline transport pilot, with one, pilot-rated passenger aboard, was departing runway 36 on a scheduled commuter flight. The pilot said that about 100 feet above the runway, he retracted 10 degrees of flaps. He added that as the airplane climbed to about 200 feet above the runway, he retracted the remaining 10 degrees of flaps, and the airplane descended while rolling to the left. The pilot stated that he had to apply full right aileron to keep the airplane upright. He said full power was already applied to the engine, but the airplane continued to descend. The airplane landed on the runway, about 200 feet from the runway threshold, and continued off the end of the runway, into snow-covered terrain. The pilot stated that during his preflight inspection, he removed an accumulation of ice and snow from the wings and empennage. Due to scheduling delays, the flight did not depart until about 2 hours after the initial preflight. The pilot said that prior to departure, he did not recheck for any additional frost accumulation. The airplane sustained substantial damage to the propeller, fuselage, and wings.

Probable cause

The pilot's inadequate preflight and his failure to remove snow and airframe ice from the airplane.

  • 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.
