This creates a risk that pilots could accidentally bump and activate it when getting into the cockpit. Accidentally disarming the stick pusher — a critical safety system that pushes the control stick forward to prevent aerodynamic stalls — could be dangerous in flight.\n\n**Who must act:**\nOwners or operators of Dornier 328-100 aircraft with serial numbers 3005 through 3103.\n\n**What they must do:**\n- Inspect the switch/light on the centre pedestal\n- If needed, relocate a component (the switch spacer) on the right-hand miscellaneous panel, following specific manufacturer instructions (Fairchild Dornier Service Bulletin SB-328-27-279)\n\n**When:**\nNo later than the next \"A-Check\" (a routine maintenance inspection) after 19 January 2006.\n\n**Why it matters:**\nPrevents accidental deactivation of a life-critical stall protection system. The directive references a German aviation safety notice (LBA AD 1999-054), showing this is part of international coordination on this safety issue."}},"importantCases":[],"_links":{"self":"/api/acts/ad-do-328-30-stick-pusher-disarm-switch-light","history":"/api/acts/ad-do-328-30-stick-pusher-disarm-switch-light/history","analysis":"/api/acts/ad-do-328-30-stick-pusher-disarm-switch-light/analysis","conflicts":"/api/acts/ad-do-328-30-stick-pusher-disarm-switch-light/conflicts","importantCases":"/api/acts/ad-do-328-30-stick-pusher-disarm-switch-light/important-cases","documents":"/api/acts/ad-do-328-30-stick-pusher-disarm-switch-light/documents"}}
