Accident Summary
On August 21, 2018, at approximately 12:15 UTC, a Cessna 150M, registration LV-CZA, departed from Coronel Olmedo Aerodrome in Córdoba, Argentina, for a training flight with a student pilot and an instructor on board. After about 35 minutes of flight, while performing a climb maneuver, the aircraft entered an incipient stall condition, which progressed into a spin. The spin completed six turns, and the aircraft could not be recovered, ultimately impacting the ground. The accident occurred during daylight hours under good weather conditions. The aircraft was destroyed, and both occupants sustained fatal injuries.
Aircraft and Personnel
The aircraft involved was a Cessna 150M, serial number not specified in the report. The flight instructor held a provisional flight instructor certificate, issued on July 20, 2018, which was valid for all privileges. The instructor, a 27-year-old Argentine male, had completed the theoretical instructor course via distance learning in 2017. The student pilot's qualifications were not detailed in the report. Both pilots were the sole occupants of the aircraft.
Sequence of Events
The flight departed Coronel Olmedo Aerodrome at 12:15 UTC. Approximately 35 minutes into the flight, during a climb maneuver, the aircraft began to lose aerodynamic lift, leading to an incipient stall. This condition quickly developed into a spin. The aircraft rotated six times before the spin became unrecoverable. The aircraft then struck the terrain, resulting in complete destruction. The report indicates that the accident was related to in-flight loss of control and issues with recovery from unusual attitudes.
Injuries and Damage
Both the instructor and the student pilot sustained fatal injuries. The aircraft's airframe was destroyed, the engine suffered significant damage, and the propeller was destroyed with both blades deformed. No other property damage occurred.
Investigation and Findings
The investigation was conducted by the Junta de Investigación de Accidentes de Aviación Civil (JIAAC). The report identified factors related to loss of control in flight and the recovery from unusual attitudes, as well as regulatory requirements for specific maneuver training.
Probable Cause
The stated probable cause in the report is loss of control in flight.
