The installation must follow a specific scheme that has been approved by the Secretary (the relevant government authority responsible for aviation safety). Technical guidance for designing these schemes can be found in Airworthiness Advisory Circular No. 62 from March 1972.\n\n**When:** This modification had to be completed before 1 January 1974, unless it was already done earlier."}},"importantCases":[],"_links":{"self":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification","history":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification/history","analysis":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification/analysis","conflicts":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification/conflicts","importantCases":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification/important-cases","documents":"/api/acts/ad-dh-82-8-seat-restraint-installations-modification/documents"}}
