NTSB summary
On October 19, 2004, about 1200 Pacific daylight time, an Aero Vodochody L-39C, N39TJ, collided with mountainous terrain about seven miles east of Hyak, Washington, after radio and radar contact were lost at 1158. The 14 CFR Part 91 personal pleasure flight, which departed Boeing Field, Seattle, Washington, at 1146, was in an area of reported instrument meteorological conditions (IMC), and the pilot had activated his previously filed Instrument Flight Rules (IFR) flight plan. No ELT signal has been detected in the area where radar contact was lost, and the search for the aircraft was called off six days after the aircraft went missing (10/25/04). The jet aircraft, which had been issued an experimental-exhibition airworthiness certificate, was eventually located in the third week of June 2005, when some hikers came across the remains of the wreckage. About a week after they discovered the scene, the hikers realized that what they found may have been a previously undiscovered missing aircraft, so they reported their find to the FAA. Both occupants, a private pilot and his passenger, received fatal injuries, and the aircraft had been destroyed. On the day of the accident, approximately nine minutes after takeoff, the aircraft was passed from Seattle Approach Control to Seattle Center. At that time, the pilot reported that he was passing 8,000 feet for 15,000 feet. About 70 seconds later, the center controller asked the pilot if he would prefer to climb to 15,000 feet or 17,000 feet, and the pilot responded with 17,000 feet. He was then cleared to 17,000 feet by the controller.
Probable cause
The loss of aircraft control during climb to cruise due to an undetermined flight control malfunction.
