This Directive requires that the existing 6ANC size cables are replaced with larger 4ANC size cables, decreasing the likelihood of feeder cables overheating and causing damage.","sortOrder":0}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This is a discrete, single-issue airworthiness directive addressing a specific wiring safety defect.
