The work must follow instructions in \"SAAB Service Bulletin SF 340-33-028\" — a technical repair notice from the manufacturer.\n\n**Who it affects:** Anyone operating these particular SAAB SF 340A regional turboprop aircraft in Australia.\n\n**Why it matters:** The US Federal Aviation Administration (FAA) discovered the emergency lighting system didn't fully meet safety standards (specifically, the requirement for emergency floor proximity lighting that helps passengers find exits in smoke/darkness). This AD ensures Australian-registered aircraft get the same safety fix.\n\n**Key deadline:** The work had to be completed before 22 July 1989.\n\n**Cross-reference:** Also relates to \"SAD 1-030\" — likely a related service difficulty alert."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The text contains no indication that the directive alters scope compared to a prior version or was amending another instrument.
