On October 26, 2023, an instrument flight rules (IFR) Cessna S550 Citation airplane, N311G, impacted a flooded corn field approximately one mile northeast of Indianapolis Regional Airport (MQJ), Indiana. The pilot and sole passenger were fatally injured, and the aircraft was destroyed. Radar data indicated the aircraft departed from runway 7 at MQJ and began a left turn towards ATC’s assigned heading of 320ø shortly after departure. The airplane descended to approximately 1,400 feet MSL, then disappeared from radar. A witness reported seeing the airplane in a 90-degree left bank with the nose parallel to the horizon shortly after departure, and observed a nose lower slightly before rising to a level attitude. The nose of the aircraft then lowered, resulting in impact with the ground. The wreckage covered an area of approximately 270 feet long and 103 feet wide, with initial ground scar aligned at 327ø magnetic heading. The wreckage and debris field were characterized by significant fragmentation. The engines separated and were located approximately 197 feet from the impact point, roughly aligned with the ground scar. A post-impact fire incinerated approximately 80% of the airplane. The probable cause was identified as the pilot’s failure to fully advance the power levers during takeoff and initial climb, leading to insufficient airspeed and a stall, resulting in aerodynamic instability and a loss of control.On October 26, 2023, an instrument flight rules (IFR) Cessna S550 Citation airplane, N311G, impacted a flooded corn field approximately one mile northeast of Indianapolis Regional Airport (MQJ), Indiana.
