If you own or operate one of these specific aircraft, you **must** complete this inspection within 100 hours of flying time after 31 May 1976. The directive references a manufacturer service bulletin (GAF SB No. N22.32.4) which contains the detailed inspection instructions. Failing to comply means the aircraft cannot legally fly — it's about preventing accidents caused by landing gear failures.\n\n**Key point:** This is a historical directive from 1976 (indicated by \"5/76\"), so for current operations, compliance would have been required decades ago. However, it remains part of the regulatory record for these aircraft types."}},"importantCases":[],"_links":{"self":"/api/acts/ad-gaf-n22-10-main-landing-gear-inspection","history":"/api/acts/ad-gaf-n22-10-main-landing-gear-inspection/history","analysis":"/api/acts/ad-gaf-n22-10-main-landing-gear-inspection/analysis","conflicts":"/api/acts/ad-gaf-n22-10-main-landing-gear-inspection/conflicts","importantCases":"/api/acts/ad-gaf-n22-10-main-landing-gear-inspection/important-cases","documents":"/api/acts/ad-gaf-n22-10-main-landing-gear-inspection/documents"}}
