It requires owners and operators of specific Beechcraft Queen Air aeroplanes to inspect the side windows in the cabin, baggage area, and pilot compartment for defects.\n\n**Who it affects:**\n- Owners and operators of Beechcraft 65 and 70 series aeroplanes (specifically model 65-88 with serial numbers LP-1 to LP-26, LP-28, and LP-30 to LP-47)\n\n**What they must do:**\n- **Initial inspection:** Check the windows within 50 hours of flying time after 7 July 1981\n- **Ongoing inspections:** Repeat the inspection every 300 flight hours **or** every year (whichever comes first)\n- **Final fix:** Keep inspecting until the windows are replaced following Beechcraft's official service instructions (Service Instruction No. 0711-110, Revision 111)\n\n**Why it matters:**\nWindows on these aircraft have been failing during flight — both in Australia and overseas. This directive prevents potentially dangerous in-flight window failures by catching problems early through regular inspection."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-65-56-cabin-baggage-and-pilot-compartment-side-windows-inspection","history":"/api/acts/ad-beech-65-56-cabin-baggage-and-pilot-compartment-side-windows-inspection/history","analysis":"/api/acts/ad-beech-65-56-cabin-baggage-and-pilot-compartment-side-windows-inspection/analysis","conflicts":"/api/acts/ad-beech-65-56-cabin-baggage-and-pilot-compartment-side-windows-inspection/conflicts","importantCases":"/api/acts/ad-beech-65-56-cabin-baggage-and-pilot-compartment-side-windows-inspection/important-cases","documents":"/api/acts/ad-beech-65-56-cabin-baggage-and-pilot-compartment-side-windows-inspection/documents"}}
