The slides (or slide rafts used for water landings) were built with a cable that could be routed incorrectly, causing the slide to fail to inflate during an emergency.\n\n**Who must act:** Anyone operating a BAe 146 aircraft that has **slide or slide raft systems installed before a specific design fix** (called \"pre-mod HCM 70440B\").\n\n**What they must do:** Follow the repair instructions in **British Aerospace Service Bulletin 25-198** — a technical manual from the manufacturer detailing exactly how to inspect and correct the cable routing.\n\n**Why it matters:** Emergency slides must work instantly in a crisis. A slide failing to deploy could trap passengers inside a burning or sinking aircraft. The UK aviation regulator had already issued the same warning (UK CAA AD 008-05-90), so this Australian directive aligns with international safety standards.\n\n**Deadline:** The fix had to be completed before **31 July 1990**."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The AD’s scope as written (addressing slide/slide-raft systems on BAe 146 aircraft that are pre-mod HCM 70440B) matches the stated objective of correcting an incorrectly routed slide valve release cable that caused a deployment failure (Applicability; Background).
