This could cause the seats to fail or move unexpectedly during flight, creating a serious safety risk for the crew.\n\n**Who it affects:**\n- **Aircraft models:** Eurocopter SA 360 and SA 365 (Dauphin series) helicopters\n- **Specific configuration:** Only those with \"bucket seats\" and long sliding rails, *before* a specific factory modification (AMS 365A.07.1653) was applied\n\n**What must be done:**\n- **Action:** Install the doubler plate following the manufacturer's Service Bulletin No. 25.08\n- **Deadline:** Before 31 July 1981\n\n**Key point:** This directive is now historical — the compliance date passed over 40 years ago.
