Within how many days must an operator file an NTSB accident report?

The requirement for filing an NTSB accident report is specified in Title 49 of the Code of Federal Regulations, specifically Section 830.10. An operator involved in an aviation accident must file a report with the National Transportation Safety Board (NTSB) within 10 days after the accident. This timeframe ensures that sufficient information is gathered for preliminary investigation purposes without undue delay. This structured approach allows for timely responses to incidents that may affect safety standards and regulations in aviation.
