The July 26, 2021 fatal crash of a Bombardier Challenger 605 while attempting a circle-to-land approach in marginal VMC was due to “the first officer’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,” according to the NTSB final report published today. The accident near California’s Truckee-Tahoe Airport (KTRK) killed the two pilots and four passengers.
The Safety Board also faulted the flight crew for ignoring stall protection system warnings, which resulted in a left-wing stall and an impact with terrain. Contributing to the accident were the improper deployment of the flight spoilers in an apparent attempt to quickly descend from being too high, but which decreased the airplane's stall margin; the captain’s improper setting up of the circling approach; the flight crew’s “self-induced pressure to perform;” and “poor crew resource management, which degraded their decision-making.”
