Accident occurred Friday, September 15, 2006 in Maybell, CO

Aircraft: Cirrus Design Corp SR20, registration: N787SL
Injuries: 2 Fatal.

NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

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.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

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.
