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.

Prior to the night flight, the pilot obtained a "full, low-level weather briefing" and filed an instrument flight rules flight plan. Shortly after departure, the pilot encountered icing conditions and began to experience a severe vibration in the aircraft flight controls at 5,000 feet mean sea level (msl). The pilot elected to return to the departure airport. During the instrument approach to land, the airplane continued to accumulate ice on the airframe, and continued toward the terrain in a 1,500 feet per minute descent. At 1,750 feet msl, the airplane "broke out of the clouds with the windscreen completely covered with ice." Subsequently, the airplane impacted the terrain approximately 40 feet short of the runway and skidded to a stop on the runway, resulting in substantial damage to the airplane. Examination of the airplane's systems and powerplant revealed no anomalies that would have precluded normal operation. The airplane's wings and windscreen had approximately 1 inch of ice on the respective surfaces. The pilot reported that icing conditions were not forecasted or reported prior to his flight.

NTSB Probable Cause

The pilot's inadvertent encounter with icing conditions during initial climb. Contributing to the accident were the lack of visibility during the landing due to an ice covered windscreen, and the structural ice that adversely affected the flight characteristics of the airplane.
