Accident Overview
An aircraft on a local test flight at Bogotá-El Dorado Airport crashed shortly after the pilot transmitted a brief mayday message. The flight carried four crew members: two pilots and two engineers. After passing over runway 12 at an altitude of approximately 200 feet, the airplane banked left and struck the ground in flames. The aircraft was destroyed and all four occupants were killed.
Investigation Findings
The investigation determined that the exact cause of the accident could not be identified. At the moment of impact, the left propeller was feathered, while no technical anomalies were found on the left engine. However, examination of the right engine revealed that the forward bearing and connecting rod had seized. Additionally, it was reported that the pilot-in-command was not qualified to operate the aircraft type involved in the accident.
Conclusion
No official probable cause was established. The final report noted the right engine failure and the pilot's lack of qualification, but the precise sequence leading to the crash remained undetermined.
