What happened
During a circling approach characterized by strong, gusty tailwinds, the aircraft was observed by air traffic control and radar to be maneuvering at or below the minimum descent altitude of 720 feet. The flight was occurring within an overcast layer with altitudes ranging from 600 to 1,100 feet above ground level. As the aircraft moved along the left downwind leg of the airport traffic pattern, it was positioned near the runway threshold. To align with the runway, a 180-degree turn would have been necessary, requiring a bank angle of at least 45 degrees.
At the time of the maneuver, the aircraft was traveling at 100 knots. Given that the stall speed for the aircraft is estimated between 88 and 94 knots, the increased load factor from a steep bank—potentially exacerbated by the tailwind—likely raised the stall speed above the current airspeed. Eyewitnesses reported seeing the aircraft emerge from the cloud ceiling in a nose-down orientation.
Findings
Investigation into the incident suggests that the pilot encountered an aerodynamic stall while executing a sharp bank to align with the runway. While toxicological analysis detected the presence of zolpidem, the concentration was below therapeutic levels and consistent with use the previous evening, leading investigators to conclude the pilot was not impaired by the medication. Furthermore, a physical inspection of the wreckage showed no evidence of mechanical failure prior to the impact.
