The area to be inspected includes the upper part of the “I” section shank, the hollow crossbar and the brake pedal attachment lugs. Particular attention must be paid to the fillet radii and holes.\n\nCompliance: 1. Initially inspect before the issue of the next maintenance release after 31 October 1987. Re-inspect at intervals not to exceed 12 months.\n\n2. Inspect before flight if the aircraft has been parked for more than 3 months with the rudder pedals locked.\n\nNote: The Maintenance Manual prohibits towing with the rudder pedals locked. This practice may also cause premature cracking.\n\nBackground: A review of cracked rudder pedals suggests that the primary cause of cracking is wind loads when the aircraft is parked on the ground with the rudder pedals locked, normal operating loads being a secondary factor. The inspection interval is now based on calendar time, special provision is made for aircraft parked in the open for long periods and a warning has been added about correct towing practice.","sortOrder":0}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":2038},"content_quality":"ok","complexity_score":3,"scope_assessment":{"changed":false,"description":"The amendment refines the inspection regime from flight hours to calendar time and adds specific provisions for long-term parking and towing practices, but remains focused on the original purpose of detecting cracks in rudder pedal arms."},"complexity_factors":["Requires compliance with external technical standard CAO 108.10 for inspection methodology","Conditional compliance trigger based on aircraft parking status (>3 months with locked pedals)","Technical part number specificity (P/N 50-524326, all dash numbers)","Dual inspection schedule (initial deadline plus recurring 12-monthly intervals)"],"plain_english_summary":"This directive requires owners/operators of Beechcraft 36 (Bonanza) aircraft with rudder pedal arms P/N 50-524326 to inspect the upper rudder pedal arm (I‑section shank, hollow crossbar and brake‑lug areas) for cracks using fluorescent dye‑penetrant.
