A Bombardier CL-600-2B16 Challenger 605 jet, registration N605TR, was destroyed when it impacted heavily wooded terrain while on a visual approach to runway 11 near Truckee Airport (TRK/KTRK), Truckee, California. The two pilots and four passengers were fatally injured.
The flight crew established communication with the Truckee tower controller when they were near the LUMMO waypoint, located about 9.6 nm north of the approach end of runway 20. The tower controller offered the flight crew the option of crossing over the field and enter the left downwind leg for runway 29 or to enter downwind leg for runway 11. Once the flight crew announced they were making a right turn and reported runway 11 in sight, the controller then cleared them to land on runway 11 and informed them that the airplane was not in sight. The flight crew acknowledged the clearance, which was their final radio communication.
According to witnesses, the airplane was in a nose down attitude and steep left turn during its last few seconds of flight. The aircraft struck trees and then the ground. The airplane was consumed by postcrash fire.

Probable Cause and Findings:
The first officer’s (FO’s) improper decision to attempt to salvage an unstabilized approach by executing a steep left turn to realign the airplane with the runway centerline, and the captain’s failure to intervene after recognizing the FO’s erroneous action, while both ignored stall protection system warnings, which resulted in a left-wing stall and an impact with terrain.
Contributing to the accident was the FO's improper deployment of the flight spoilers, which decreased the airplane's stall margin; the captain’s improper setup of the circling approach; and the flight crew’s self-induced pressure to perform and poor crew resource management, which degraded their decision-making.
