A Hawker 900XP crashed in Utah on Feb. 7, 2024, after the flight crew conducted a post-maintenance stall test in icing conditions, resulting in wing contamination, degraded aerodynamic performance, and a loss of control from which the pilots were unable to recover, according to the NTSB’s final report. The accident killed both crew members.

The business jet departed on a Part 91 positioning flight from Grand Junction Regional Airport (KGJT), Colorado, after the airplane underwent routine maintenance that included the removal and reinstallation of the wing leading edges and de-icing panels. While climbing to 20,000 feet msl, the crew initiated a planned stall warning and identification system check. Flight data showed the airplane slowed and pitched up before entering a stall at essentially the same moment the stick shaker activated.
