The direction requires this company to keep its **navigation logs** (detailed records of flight routes, positions, and calculations used during flights) for **6 months** after international flights.\n\n**Who it affects:**\n- **Combined Aviation Services Pty Ltd** (a specific airline/operator with Aviation Reference Number 553573)\n- The company's pilots and operational staff who must maintain these records\n\n**Why it matters:**\nNavigation logs are crucial for safety investigations if something goes wrong. Normally, aviation records have specific retention periods. This direction appears to impose a specific 6-month retention requirement on this particular operator, possibly because of a safety concern, audit finding, or to ensure documentation is available for regulatory oversight.\n\n**Key points:**\n- This is **not a general law** applying to all airlines—it's a targeted direction to one company\n- It was issued under **Regulation 80** of the Civil Aviation Regulations 1988, which gives the Director of Aviation Safety power to issue directions about record-keeping\n- The 6-month period may be longer or different from standard requirements, suggesting enhanced oversight"},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The instrument, as provided, imposes a narrow, time-limited retention obligation on a named operator for navigation logs of international operations.
