NTSB summary
On Saturday, June 5, 2004, approximately 1740 Pacific daylight time, an experimental Gann Glasair II-S RG, N711LN, impacted the terrain about 40 miles southeast of Baker City, Oregon. The private pilot, who was the sole occupant, received fatal injuries, and the aircraft, which was owned and operated by the pilot, was destroyed. The 14 CFR Part 91 personal pleasure flight, which departed Portland International Airport, Portland, Oregon, at 1600, had reportedly entered an area conducive to airframe icing prior to the accident. The pilot had filed and activated an IFR flight plan for the flight to Vance Brand Airport, Longmont, Colorado. There was no report of an ELT activation. A review of the recorded radio transmissions between the Salt Lake City Air Traffic Control Center and the pilot of N711LN revealed that about one hour and thirty minutes after takeoff, while cruising at 14,000 feet, the pilot requested a climb to 17,000 feet. Upon being cleared to that altitude, the pilot advised Center that he was experiencing light to moderate icing. About five minutes after being cleared to 17,000 feet, the pilot began a transmission with an expletive, and then stated "Mayday, 711LN in a bad spin." About 15 seconds later there was another transmission from the pilot, but his words were not intelligible, except for the aircraft call sign. Immediately after that transmission, the controller asked the pilot if he was calling Center, and the pilot transmitted, "Yeah, Mayday, we're in a bad spin to the left." After about 10 more seconds, the controller again asked if N711LN was calling
Probable cause
The pilot's inadequate in-flight planning/decision and his failure to maintain an airspeed above stall speed (Vs) after encountering airframe icing during cruise flight. Factors include the pilot's intentional continuation of his flight along the planned route after encountering icing conditions.
