Cirrus Design CORP SR22 accident near Marion, Illinois, June 10, 2016

The NTSB's narrative final · quoted from the NTSB record

After performing six touch-and-go maneuvers without incident, the pilot receiving instruction and flight instructor contacted air traffic control and requested a climb to 3,000 ft to perform a simulated engine failure and landing maneuver. The air traffic controller cleared the pilots for the maneuver and requested that they report the base-to-final turn to the runway, and the pilot acknowledged the instructions. The controller reported that, about 4 minutes later, he observed the airplane in a descending left turn. As the airplane approached the runway, he observed the right wing lift, and the airplane appeared to stall and roll to the right before it impacted terrain. Another witness reported that she could see the entire top of the airplane with the wings pointed up and down, and that she saw one wing strike the terrain shortly thereafter. The flight instructor had no recollection of the accident. Examination of the wreckage revealed no evidence of preimpact mechanical malfunctions or failures that would have precluded normal operation. A review of the flight and engine data from the accident flight revealed that the airplane climbed to about 3,000 ft, and then circled while remaining in the airport traffic pattern area. The airplane then descended, and the airspeed gradually decreased from about 110 to about 87 kts. During the final 3 seconds of the recording, vertical, lateral, and longitudinal accelerations increased to recorded peaks of 1.4 g, -0.2 g, and 0.4 g, respectively. During the final second of the recording, the airplane was at 646 ft when it entered a descending left turn; the roll value increased from 36 degrees to 45 degrees left, and the pitch value ranged from -0.5 degrees to 2.4 degrees. The witness statements and flight data are consistent with a the pilots failing to maintain adequate airspeed and exceeding the wing's critical angle of attack, which resulted in a subsequent aerodynamic stall and loss of control. The airplane's parachute system was found deployed, which likely occurred during the impact sequence. Given the low altitude at which the aerodynamic stall occurred (about 646 ft), it is unlikely that preimpact deployment of the system would have positively affected the outcome of the accident.
