If they fail, passengers and crew cannot evacuate quickly.\n\n**Who it affects:**\n- Anyone who owns or operates a Boeing 747 model that uses specific propellant cartridges made by Rocket Research Company (RRC), as identified in service bulletins RRC/SB 25-015 or RRC SB 0016.\n\n**Why it matters:**\n- Faulty propellant cartridges could mean escape slides fail to inflate during an emergency, trapping people on board. This directive ensures these critical safety components are checked to prevent catastrophic failure during evacuation.\n\n**How to comply:**\n- Follow the inspection requirements set out in **FAA Airworthiness Directive 78-05-08** (the US aviation safety regulator's equivalent order) or **Boeing Service Bulletin 747-25-2373, Revision 1**."},"flash_summary":{"complexity_score":4,"scope_assessment":{"changed":false,"description":"The instrument is labelled as Amendment 1 (AD/B747/11 Amdt 1) but the text provided does not set out any explicit change to the applicability or scope compared with an earlier version.
