Technical guidance is available in *Airworthiness Advisory Circular No. 62* from March 1972 to help design the installation.\n\n**Who it affects:**\nAnyone who owns or operates a Helio Courier series aeroplane.\n\n**Why it matters:**\nThis improves crash survivability by ensuring occupants are properly restrained, preventing them from hitting the controls or windshield during sudden deceleration.\n\n**Compliance deadline:**\nThe modifications had to be completed before **1 October 1973**."}},"importantCases":[],"_links":{"self":"/api/acts/ad-helio-2-front-seat-restraint-installation-modification","history":"/api/acts/ad-helio-2-front-seat-restraint-installation-modification/history","analysis":"/api/acts/ad-helio-2-front-seat-restraint-installation-modification/analysis","conflicts":"/api/acts/ad-helio-2-front-seat-restraint-installation-modification/conflicts","importantCases":"/api/acts/ad-helio-2-front-seat-restraint-installation-modification/important-cases","documents":"/api/acts/ad-helio-2-front-seat-restraint-installation-modification/documents"}}
