The old aircraft-specific rule has been replaced by a broader general directive (**AD/GENERAL/74 Amendment 1**) that covers this requirement across multiple aircraft types. This simplifies compliance by consolidating overlapping rules into one standard.\n\n**Who is affected:** Owners, operators, and maintenance engineers working on Cessna 337 series aircraft (the twin-boom \"push-pull\" Skymaster)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-337-10-front-seat-restraint-installations-modification-cancelled","history":"/api/acts/ad-cessna-337-10-front-seat-restraint-installations-modification-cancelled/history","analysis":"/api/acts/ad-cessna-337-10-front-seat-restraint-installations-modification-cancelled/analysis","conflicts":"/api/acts/ad-cessna-337-10-front-seat-restraint-installations-modification-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-337-10-front-seat-restraint-installations-modification-cancelled/important-cases","documents":"/api/acts/ad-cessna-337-10-front-seat-restraint-installations-modification-cancelled/documents"}}
