How long should cockpit voice and flight recorder data be retained after an accident?

The appropriate retention period for cockpit voice and flight recorder data after an accident is 60 days. This timeframe is essential for ensuring that crucial information regarding the flight is available for investigation by safety authorities.

The rationale behind this 60-day retention period is that it provides a balance between the need for timely access to data for investigative purposes and the practical considerations of data storage and management. The flight recorder data can include vital information that helps in determining the cause of an accident, which is critical for improving aviation safety standards and preventing future incidents.

Choosing this specific duration facilitates a thorough examination of the events leading up to the incident, ensuring that investigators have sufficient time to analyze the recordings in conjunction with other available evidence. This period has been established in line with regulatory guidelines and practices within the aviation industry, underscoring the importance of having reliable data accessible during the investigative process.
