What happened
Shortly after takeoff, the crew reported a partial loss of flight display information. The pilot declared an emergency and returned to the departure airport, where the aircraft landed without further incident.
The investigation
This event marked the fourth reported instance of this specific type of occurrence for this make and model airplane under the operator's fleet. Investigators examined the aircraft but were unable to identify any mechanical failure that would have caused the loss of flight displays. Additionally, the manufacturer reviewed the electrical system design and could not identify a design failure.
Findings
The investigation revealed no identifiable cause for the partial loss of flight display information. The lack of a definitive mechanical or design failure suggests an intermittent issue that was not replicated during post-accident analysis.
