The safety requirement hasn't disappeared—it's just been moved into a broader general directive (AD/GENERAL/74 Amendment 1) that covers multiple aircraft types under one umbrella.\n\n**Who this affects:** Owners and operators of Percival Vega Gull series aircraft. You no longer need to check this specific directive number for seat restraint rules; instead, look at the general requirements in AD/GENERAL/74."}},"importantCases":[],"_links":{"self":"/api/acts/ad-gull-3-front-seat-restraint-installations-modification-cancelled","history":"/api/acts/ad-gull-3-front-seat-restraint-installations-modification-cancelled/history","analysis":"/api/acts/ad-gull-3-front-seat-restraint-installations-modification-cancelled/analysis","conflicts":"/api/acts/ad-gull-3-front-seat-restraint-installations-modification-cancelled/conflicts","importantCases":"/api/acts/ad-gull-3-front-seat-restraint-installations-modification-cancelled/important-cases","documents":"/api/acts/ad-gull-3-front-seat-restraint-installations-modification-cancelled/documents"}}
