This directive implements a modification which is intended to prevent failure of the engine fire detector system to annunciate a fire warning message to flight crew following a severe engine failure. Failure to annunciate a fire warning could lead to delayed or improper flight crew response to the engine failure.","sortOrder":0}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This is a discrete, targeted airworthiness directive addressing a specific safety defect in a specific aircraft/engine combination.
