NTSB narrative
The pilot contacted ARTCC and stated he needed a lower altitude, as he was encountering icing conditions. Several altitude changes were assigned. Ultimately the pilot was assigned a block altitude from 12,000 feet to 13,000 feet. The pilot reported that they were in serious icing conditions and the controller cleared the pilot to an altitude of 11,000 feet. Shortly thereafter, voice and radar communications with the airplane were lost. The wreckage was located scattered over a 1.5 mile area between Colorado and Wyoming. Signatures at the scene showed evidence consistent with a ground impact deployment of the parachute recovery system, resulting in fragmentation of the airplane, as it was drug by high winds. An examination of the remaining airplane systems revealed no anomalies. Thunderstorm activity existed along the route of flight along with severe icing and turbulence. The pilot had not obtained a full weather briefing prior to the flight.
Probable cause
The pilot's improper in-flight planning and decision making resulting in an inadvertent encounter with severe icing conditions during cruise flight and subsequent loss of aircraft control. Contributing factors include the pilot's failure to obtain a weather briefing, the thunderstorm, conditions conducive for structural icing, and the pilot's failure to deploy the parachute recovery system.

- 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, coordinates. 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.
