A private pilot without instrument rating encountered IMC about 15 minutes after departure, lost control of the airplane, and impacted snow-covered terrain. The pilot had obtained weather briefings indicating IFR conditions.

Accident Overview

Approximately 15 minutes after departure, the airplane encountered instrument meteorological conditions (IMC). Subsequently, the non-instrument rated private pilot lost control of the airplane and impacted snow-covered terrain. The impact occurred with the airplane in a right wing low, nose-down attitude.

Preflight Planning

Prior to the cross-country flight, the pilot obtained three standard weather briefings: two on the previous day and one on the morning of the accident. These briefings included information about instrument flight rules (IFR) conditions along the planned route. According to the briefing conversation and a statement from a friend, the pilot intended to land before reaching the destination if the weather was not visual flight rules (VFR), and then wait for conditions to improve. The pilot also informed the weather briefer that he needed to be in Houston, Texas by 7 o'clock on the day of the accident.

Flight Data

Radar data indicated that after departing, the airplane traveled on a southeasterly heading. For the first 15 minutes of flight, the airplane maintained a level altitude and a consistent heading. During the final minute of flight, the airplane entered a descent of 2,500 feet per minute, followed by a climb of 3,000 feet per minute, and then a descent of 1,300 feet per minute. The heading also varied by several degrees during this period.

Post-Accident Examination

No anomalies were noted with the airframe and engines upon examination.
