It requires owners and operators of **Dornier DO-27 aircraft** to install a specific stall warning system modification kit.\n\n**What it does:**\n- Mandates the installation of a stall warning device (an alarm system that warns pilots when the aircraft is flying too slowly and at risk of stalling, which means losing lift and potentially crashing)\n- Specifies the exact equipment required: modification kit drawing number 27-836 from the manufacturer\n- Set a hard deadline of **1 October 1973** for completing the installation\n\n**Who it affects:**\n- Anyone operating or maintaining Dornier DO-27 series aeroplanes (all models)\n\n**Why it matters:**\nStall warning systems are critical safety equipment that give pilots early warning to prevent loss of control. This directive ensured these aircraft met minimum safety standards by a specific date."}},"importantCases":[],"_links":{"self":"/api/acts/ad-do-27-10-stall-warning-system-installation","history":"/api/acts/ad-do-27-10-stall-warning-system-installation/history","analysis":"/api/acts/ad-do-27-10-stall-warning-system-installation/analysis","conflicts":"/api/acts/ad-do-27-10-stall-warning-system-installation/conflicts","importantCases":"/api/acts/ad-do-27-10-stall-warning-system-installation/important-cases","documents":"/api/acts/ad-do-27-10-stall-warning-system-installation/documents"}}
