It requires specific modifications to the pilot seats in certain GAF N22 and N24 series aeroplanes (small aircraft).\n\n**What it does:**\n- Orders owners/operators of specific aircraft (by serial number) to relocate both pilot seats\n- The modification must follow the manufacturer's Service Bulletin (SB N22.25.1) — essentially the manufacturer's official repair instructions\n\n**Who it affects:**\n- Owners and operators of:\n  - GAF N22 models with serial numbers 2 and 4\n  - GAF N22B models with serial numbers 7, 25, 26, 27, and 28\n\n**Why it matters:**\n- Airworthiness Directives are legally binding. You cannot fly these aircraft until the work is done.\n- The deadline was 1 May 1977 — this is a historical directive from 1977 (the \"5/77\" indicates May 1977)\n- The seat relocation likely addressed a safety issue with pilot positioning, visibility, or control reach\n\n**Key takeaway:** If you own one of these specific aircraft, your pilot seats needed to be moved to a new position by May 1977, following the manufacturer's instructions exactly."}},"importantCases":[],"_links":{"self":"/api/acts/ad-gaf-n22-11-amdt-1-relocation-of-pilot-seat-installations","history":"/api/acts/ad-gaf-n22-11-amdt-1-relocation-of-pilot-seat-installations/history","analysis":"/api/acts/ad-gaf-n22-11-amdt-1-relocation-of-pilot-seat-installations/analysis","conflicts":"/api/acts/ad-gaf-n22-11-amdt-1-relocation-of-pilot-seat-installations/conflicts","importantCases":"/api/acts/ad-gaf-n22-11-amdt-1-relocation-of-pilot-seat-installations/important-cases","documents":"/api/acts/ad-gaf-n22-11-amdt-1-relocation-of-pilot-seat-installations/documents"}}
