For some aircraft, they must also install a **cover on the slide inflation cylinder** (the gas canister that inflates the slide).\n\n**Who it affects:**\n- All Boeing 737-100, -200, -200C, -300, -400, and -500 series planes\n- All Boeing 737-600, -700, and -800 series planes\n\nSpecifically, those listed in three Boeing Service Bulletins from May 2000.\n\n**Why it matters:**\nThe modification prevents **escape slides from failing to deploy or inflate during an emergency evacuation**. Without this fix, passengers and crew could be trapped inside a plane during an emergency because the inflatable escape slide wouldn't work.\n\n**What must be done:**\nOperators must follow the technical instructions in **FAA AD 2001-15-01** (the US aviation safety regulator's equivalent order). The work had to be completed by deadlines specified in that document, with this Australian order taking effect on **29 November 2001**."}},"importantCases":[],"_links":{"self":"/api/acts/ad-b737-166-escape-slide","history":"/api/acts/ad-b737-166-escape-slide/history","analysis":"/api/acts/ad-b737-166-escape-slide/analysis","conflicts":"/api/acts/ad-b737-166-escape-slide/conflicts","importantCases":"/api/acts/ad-b737-166-escape-slide/important-cases","documents":"/api/acts/ad-b737-166-escape-slide/documents"}}
