The complex instructions from the second local controller during the pilot's go-around following her third landing attempt, were unnecessary at that time and likely distracted the pilot from monitoring critical flight parameters. The initial local controller elected to keep the airplane in the traffic pattern rather than transferring the airplane to an approach controller for resequencing when airline traffic interrupted the pilot's first landing attempt and when the pilot displayed difficulty landing the airplane on her second landing attempt. The air traffic control instructions given to the pilot during the three approaches were complex and potentially distracting.
Postaccident examination of the airframe and engine did not reveal any anomalies that would have precluded normal operation. Rather, the airplane's airspeed was 58 KIAS when the pilot raised the airplane's flaps while in a left turn, which resulted in exceedance of the critical angle of attack and a subsequent aerodynamic stall and spin into terrain. Data retrieved from the airplane revealed that, during the go-around, the pilot did not follow the recommended go-around procedure specifically, the pilot did not attain a speed between 81 to 83 knots indicated airspeed (KIAS) before raising the flaps. The new local controller then issued the pilot a lengthy clearance as the pilot was performing the go-around procedure. On this approach, the pilot again had difficulty descending fast enough to make a safe landing, and she elected to perform another go-around. During the airplane's third approach, a new local controller came on duty. The pilot was instructed to go around twice by the local controller the first time because an air carrier airplane was overtaking the accident airplane and the second time because the airplane was too high to make a safe landing.
While attempting to sequence the airplane between airplanes, the air traffic controller issued numerous instructions to the pilot, which included changing runways multiple times. The pilot was attempting to land the airplane at a busy airport with high volume airline traffic.
