Owners must install proper safety harnesses (seat belts) in the front seats of every affected plane.\n\n**Who it affects:** Anyone operating or maintaining Cessna 336 series aircraft, specifically addressing the pilot and front passenger seats.\n\n**Key requirement:** The seat belt modification must follow a design scheme approved by the Secretary (the relevant government department head). All affected aircraft had to comply by **1 September 1972**.\n\n**Why it matters:** This prevents serious injury during turbulence, hard landings, or accidents by ensuring front-seat occupants are properly restrained."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-336-6-front-seat-restraint-installations-modification","history":"/api/acts/ad-cessna-336-6-front-seat-restraint-installations-modification/history","analysis":"/api/acts/ad-cessna-336-6-front-seat-restraint-installations-modification/analysis","conflicts":"/api/acts/ad-cessna-336-6-front-seat-restraint-installations-modification/conflicts","importantCases":"/api/acts/ad-cessna-336-6-front-seat-restraint-installations-modification/important-cases","documents":"/api/acts/ad-cessna-336-6-front-seat-restraint-installations-modification/documents"}}
