How long must flight data recorders be retained after an incident subject to mandatory reporting?

Flight data recorders, often referred to as black boxes, are crucial in investigating aviation incidents. Regulations stipulate that these recorders must be retained for a specific duration after an incident to ensure that relevant data can be accessed for analysis and investigation.

The correct retention period mandated is 60 days following an incident subject to mandatory reporting. This timeframe allows investigators sufficient opportunity to access the data and conduct thorough examinations of the circumstances surrounding the incident. It is an essential practice to preserve this data, given its role in enhancing safety and preventing future occurrences.

Other durations such as 30 days, 90 days, or 120 days are not in line with the established regulations, which specify the 60-day requirement as the correct period for retaining flight data recorders after incidents subject to mandatory reporting.
