It requires owners and operators of specific Pacific Aerospace 750XL aircraft to inspect critical wing attachment points.\n\n**What it does:**\n- **Targets:** Pacific Aerospace 750XL aircraft with serial numbers 101 through 115 (15 specific planes)\n- **The problem:** Manufacturing tolerances in the wing assembly may have caused deformation in the \"lugs\" (metal brackets/bolts that attach the outer wings to the centre wing section). This could shorten the safe lifespan of these critical structural components.\n- **The fix:** Owners must inspect the wing attachment lugs for condition, alignment and clearance, following a specific manufacturer's service bulletin (PACSB/XL/015 Issue 3).\n\n**Who it affects:**\n- Owners and operators of the affected aircraft\n- Maintenance organisations servicing these planes\n\n**Why it matters:**\nWing attachment failures are catastrophic. This directive prevents potential structural failure by catching manufacturing defects before they cause accidents. The 300-hour compliance window gives operators reasonable time to schedule the inspection without grounding aircraft immediately.\n\n**Key deadline:** Inspection must be completed within 300 flight hours after 7 July 2005."}},"importantCases":[],"_links":{"self":"/api/acts/ad-750xl-5-outer-wing-attachments","history":"/api/acts/ad-750xl-5-outer-wing-attachments/history","analysis":"/api/acts/ad-750xl-5-outer-wing-attachments/analysis","conflicts":"/api/acts/ad-750xl-5-outer-wing-attachments/conflicts","importantCases":"/api/acts/ad-750xl-5-outer-wing-attachments/important-cases","documents":"/api/acts/ad-750xl-5-outer-wing-attachments/documents"}}
