Think of it like a compulsory recall notice, but for aircraft rather than cars.\n\n**What it does:** It requires owners and operators of specific SAAB Safir aeroplane models (the 91B, 91B-2, 91C, and 91D) to inspect or fix a problem with the fuel pump actuating system. Specifically, they must follow the manufacturer's Service Bulletin (SB 91.4.003) — a technical instruction manual for repairs.\n\n**Why it matters:** The manufacturer received a report that the cable assembly controlling the manual fuel pump failed during an emergency. If this cable breaks when a pilot needs extra fuel pressure in an emergency, the engine could lose power and the aircraft could crash. This directive forces operators to address the defect before it causes an accident.\n\n**Who must act:** Anyone operating the affected SAAB Safir models in Australia.\n\n**When they must act:** Within 100 hours of flying time after 31 May 1986. This is a \"time in service\" deadline — it counts only when the engine is running, not calendar time."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The text sets a specific corrective requirement for identified SAAB Safir models and a fixed compliance period; it does not indicate any extension, narrowing, or amendment to a prior scope within the instrument itself.
