Analysis

The two commercially certificated instrument rated flight instructors departed Ellensburg at approximately 1120 PST on a local flight. Both pilots had appointments at 1300 hours PST. VFR conditions prevailed in lower terrain near Ellensburg, however, a scattered to overcast cloud layer existed at approximately 5000 feet MSL throughout the area. Additionally, witnesses reported fog & obscuration in higher terrain throughout the area near the site within a few hours subsequent to the accident. Evidence indicated that a course reversal was being executed concurrent with tree impacts at approximately 4425 feet MSL while overflying rising/mountainous terrain. There was no record that either pilot had received any formal mountain flying training.
