It was cancelled in January 2008 and replaced by a broader safety directive (AD/GENERAL/74 Amendment 1) that covers shoulder harness requirements for a wider range of aircraft types. If you own one of these aircraft, you don't need to follow this specific rule anymore, but you must comply with the newer general directive instead."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-180-29-front-seat-restraint-installations-cancelled","history":"/api/acts/ad-cessna-180-29-front-seat-restraint-installations-cancelled/history","analysis":"/api/acts/ad-cessna-180-29-front-seat-restraint-installations-cancelled/analysis","conflicts":"/api/acts/ad-cessna-180-29-front-seat-restraint-installations-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-180-29-front-seat-restraint-installations-cancelled/important-cases","documents":"/api/acts/ad-cessna-180-29-front-seat-restraint-installations-cancelled/documents"}}
