After incorporation of Service Kit No. 150 continue inspection of torque tube per SB 168 every 100 hours time in service for 5 consecutive inspections without defect.\n\nBackground: The manufacturer has received reports of aileron oscillation in flight and later reports of looseness in the aileron torque tube joints of those aeroplanes modified with Service Kit 150. This revision allows the option of continued repetitive inspection in lieu of incorporation of the service kit. If the Service Kit is installed a programme of inspection of torque tubes is required thereafter.","sortOrder":0}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":2628},"content_quality":"ok","complexity_score":3,"scope_assessment":{"changed":false,"description":"This amendment maintains the original scope covering AA-5 series aileron systems.
