The original 1972 rule requiring upper torso restraints (seatbelts with shoulder straps) on aircraft certified before 1967 hasn't disappeared—it's just been consolidated into a general safety rule (AD/GENERAL/74) that applies to all aircraft types, rather than maintaining a separate rule just for Piaggio P166s. This streamlines compliance by removing redundant paperwork while keeping the safety standard intact."}},"importantCases":[],"_links":{"self":"/api/acts/ad-p166-35-front-seat-restraint-installations-modification-cancelled","history":"/api/acts/ad-p166-35-front-seat-restraint-installations-modification-cancelled/history","analysis":"/api/acts/ad-p166-35-front-seat-restraint-installations-modification-cancelled/analysis","conflicts":"/api/acts/ad-p166-35-front-seat-restraint-installations-modification-cancelled/conflicts","importantCases":"/api/acts/ad-p166-35-front-seat-restraint-installations-modification-cancelled/important-cases","documents":"/api/acts/ad-p166-35-front-seat-restraint-installations-modification-cancelled/documents"}}
