Subsequent investigation revealed a component failure which caused the oven motor to continue running when it should have switched off. This resulted in the motor overheating and causing smoke in the aircraft cabin.\n\nThis directive requires a modification incorporating a relay, the modification is designed to ensure that the motor switches off and does not overheat.","sortOrder":0}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This is a standard, narrow Airworthiness Directive targeting a specific safety defect in specific aircraft galley equipment.
