What happened
On December 6, 2008, at approximately 13:50 UTC, a CM170 Fouga Magister, registration F-AZKH, was conducting a local flight departing from Albi le Séquestre aerodrome. At 13:39, the pilot announced via radio that he would begin "evolutions."
Witnesses observed the aircraft performing vertical maneuvers and rolls at a very low altitude. During these maneuvers, the aircraft's longitudinal axis appeared unstable. The aircraft subsequently entered a descending flight path, striking a field near Gaillac. The impact was followed by a fire that destroyed the aircraft. The pilot, a 61-year-old experienced aviator, sustained fatal injuries in the crash.
The investigation
The investigation focused on the flight path, the aircraft's mechanical condition, and the pilot's training history. Investigators examined the wreckage, which was distributed in three main zones, and analyzed the engines and fuel filters; no mechanical failures or fuel contamination were identified. Radar and radio recordings confirmed the aircraft's trajectory toward the accident site.
Investigators also reviewed the pilot's training records. While the pilot held a valid type rating for the CM170 Fouga Magister, his training was focused on normal and emergency procedures rather than aerobatics. Notably, an instructor who had recently conducted a proficiency check noted that the pilot had previously requested to perform a barrel roll and had been cautioned against performing such maneuvers alone.
Findings
- The aircraft was operating outside the pilot's established competency level.
- The pilot attempted aerobatic maneuvers without receiving adequate formal training for this specific aircraft type.
- The maneuvers were performed at an insufficient altitude, leaving no margin for error during the loss of control.
- The pilot's enthusiasm and tendency to overestimate his abilities contributed to the decision to attempt unauthorized maneuvers.
