A leaking fire extinguisher in a toilet compartment could fail during a fire, putting passengers and crew at serious risk.\n\n**What must happen:**\n- **Remove** the affected extinguishers from aircraft\n- **Inspect and replace** them following the manufacturer's Service Bulletin 26-110\n- **Deadline:** Before 23 July 1998\n- **Effective date:** 23 April 1998\n\n**Cross-reference:** This aligns with a UK aviation safety notice (CAA(UK) AD 007-11-97), showing international coordination on this defect."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The AD's scope is narrowly defined and matches the stated safety concern: it applies only to First Technology spherical toilet extinguishers Halon 1211/1301 with serial numbers 7967–10356 (Applicability) in response to a manufacturing change at SN 7967 that caused leakage (Background).
