Think of it as a \"recall notice\" for aircraft, but legally binding.\n\n**What it does:** It requires owners and operators of specific Boeing 767 aeroplanes to **modify the latch hook** on the number two flight station window (the window next to the pilot/co-pilot). The modification must follow Boeing's official repair instructions (Service Bulletin 767-56-0002).\n\n**Why it matters:** The window latch was giving **false \"closed\" readings** — making pilots think the window was secure when it wasn't. This caused pilots to abort takeoffs and turn flights around unnecessarily. Worse, an improperly secured window at altitude could be dangerous. The fix prevents these false signals and ensures the window actually locks properly.\n\n**Who must comply:** Anyone operating Boeing 767s with \"line numbers\" (manufacturing serial numbers) 1 through 114 — essentially the earliest production models.\n\n**Deadline:** The modification had to be completed before 11 April 1997."}},"importantCases":[],"_links":{"self":"/api/acts/ad-b767-83-flight-station-window-latch","history":"/api/acts/ad-b767-83-flight-station-window-latch/history","analysis":"/api/acts/ad-b767-83-flight-station-window-latch/analysis","conflicts":"/api/acts/ad-b767-83-flight-station-window-latch/conflicts","importantCases":"/api/acts/ad-b767-83-flight-station-window-latch/important-cases","documents":"/api/acts/ad-b767-83-flight-station-window-latch/documents"}}
