What happened
During a local training session at Porto Alegre-Salgado Filho Airport, an aircraft was being operated by two crew members, consisting of an instructor and a pilot undergoing a check flight. While the aircraft was flying at a low altitude directly over the runway, the instructor intentionally deactivated the right engine to simulate an in-flight engine failure.
Following the shutdown, the aircraft experienced a significant roll toward the right side. The instructor attempted to stabilize the flight by applying rudder input; however, the aircraft reached a critical attitude that could not be recovered through standard maneuvers. In response to the deteriorating flight conditions, power was reduced on the remaining engine, leading to a crash landing. The incident resulted in two injuries (both crew members sustained slight injuries) and the total loss of the aircraft due to damage exceeding repair capabilities.
Findings
- The instructor's decision to perform an engine shutdown at a low altitude over the runway contributed to the loss of control.
- An error in judgment by the instructor during the simulation maneuver led to the aircraft reaching an unrecoverable state.
