This means the pilot's or passenger's seat might not lock properly into position and could slide forward or backward unexpectedly during flight—a serious hazard. **What you must do:** Follow the manufacturer's technical instructions (Service Bulletin 85-20) to inspect and fix the seat rail installation. **When:** Complete the work within 25 hours of flight time after the directive took effect."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-185-42-seat-rail-latch","history":"/api/acts/ad-cessna-185-42-seat-rail-latch/history","analysis":"/api/acts/ad-cessna-185-42-seat-rail-latch/analysis","conflicts":"/api/acts/ad-cessna-185-42-seat-rail-latch/conflicts","importantCases":"/api/acts/ad-cessna-185-42-seat-rail-latch/important-cases","documents":"/api/acts/ad-cessna-185-42-seat-rail-latch/documents"}}
