What happened
During its inaugural production flight test, an unidentified aircraft type experienced a catastrophic loss of control. Immediately after departing the runway, the aircraft entered a sudden right-hand bank. This maneuver was followed by an equally sharp bank to the left, which ultimately led to a high-speed impact with the terrain.
The accident occurred during the initial climb phase of the flight. There were no survivors of the impact, as both pilots perished in the crash.
Findings
Post-accident investigations focused on the mechanical state of the flight control systems. A detailed inspection of the left wing identified a critical installation error: the aileron cables had been incorrectly routed, connecting to their respective bellcrank attach points backwards. This improper aileron control installation prevented stable maneuvering.
Additional contributing factors identified during the investigation included:
- Inadequate compliance verification by the manufacturer regarding equipment standards.
- Insufficient preflight inspections performed by the pilot in command.
