It mandates that owners/operators of specific helicopter models must carry out technical modifications described in two Aerospatiale Service Bulletins before the aircraft can be issued a Certificate of Airworthiness (the official document allowing an aircraft to fly legally).\n\n**Who it affects:**\n- Owners and operators of **SA 360, SA 361, SA 365C, C1, C2, and C3** model helicopters\n- Specifically those with **tail rotor block assembly No.1** that hasn't been modified by certain approved modification standards (AMS 07.9028 and AMS 07.9034)\n\n**What must be done:**\n- **For most affected helicopters:** Follow Aerospatiale Service Bulletin No. 01.15 (original, Revision 1, or Revision 2)\n- **For SA 361 and SA 365 series:** Also follow Aerospatiale Service Bulletin No. 65.10 (original, Issue 1, or Issue 2)\n\n**Why it matters:**\nAirworthiness Directives are legally binding safety requirements. If you don't comply, you cannot legally operate the aircraft. This particular directive tidies up paperwork by merging old directives without changing the actual technical requirements — making it easier for operators to know what they need to do, while maintaining the same safety standards.\n\n**Key point:** This is **Amendment 1**, which only clarifies which specific helicopters are covered — the actual safety work required hasn't changed from the original directive."},"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
