This could be caused by inadvertent squeezing or knocks on the trigger without the FULL indicator disc being broken.","sortOrder":0}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This is a discrete, time-limited airworthiness directive addressing a specific manufacturing defect in specific fire extinguisher models.
