Compliance: 1. For valves which have been actuated:\n\nWithin 500 hours time in service after 9 April 1987 or before 30 June 1987 whichever occurs first.\n\n2. For valves which have not been actuated: At the next valve refurbishment.\n\nBackground: Thread damage to the piston pin retaining cap, P/N 32652, on the float inflation valve could cause failure at future actuation of the valve. Replacement of the retaining cap after each actuation of the valve is required.","sortOrder":0}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":2203},"content_quality":"ok","complexity_score":3,"scope_assessment":{"changed":false,"description":"This airworthiness directive maintains its original scope as a targeted safety mandate addressing a specific mechanical defect.
