This prevents the seat from reclining too far backward, which could interfere with flight controls or create a safety hazard.\n\n**Why it matters:** This is a compulsory safety fix, not optional. You must follow the technical instructions in Cessna Service Letter No. 310-28 No. 4 straight away (the directive says 'forthwith,' which means immediately). You cannot legally fly the aircraft until this modification is complete."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-7-right-front-seat-back-installation-of-stop","history":"/api/acts/ad-cessna-310-7-right-front-seat-back-installation-of-stop/history","analysis":"/api/acts/ad-cessna-310-7-right-front-seat-back-installation-of-stop/analysis","conflicts":"/api/acts/ad-cessna-310-7-right-front-seat-back-installation-of-stop/conflicts","importantCases":"/api/acts/ad-cessna-310-7-right-front-seat-back-installation-of-stop/important-cases","documents":"/api/acts/ad-cessna-310-7-right-front-seat-back-installation-of-stop/documents"}}
