The inspection must follow the procedures in **Rallye Service Bulletin No. 131**.\n\n**Who it affects:** Anyone who owns, operates, or maintains any model in the Aerospatiale Rallye aircraft series.\n\n**When to comply:** The first inspection had to be done within **100 hours of flying time** after 30 September 1978. After that, ongoing inspections are required according to the schedule in the referenced service bulletin.\n\n**Why it matters:** Airworthiness Directives are legally binding safety instructions. If you don't comply, your aircraft is not considered airworthy (legal to fly).
