It mandates inspection and replacement of faulty aileron hinges.\n\n## Who it affects\nOwners and operators of PZL M18 and M18A aircraft with serial numbers 1Z 00-101 through to 1Z 021-07.\n\n## Key requirements\n- **Inspect**: Check aileron hinges at the next maintenance visit after 9 August 1990, then every 50 flight hours\n- **Replace**: If hinges are cracked or bent (deformed), swap them before flying again\n- **Permanent fix**: Installing manufacturer-modified hinge assemblies ends the inspection requirement\n\n## Why it exists\nThe manufacturer reported cracks developing in these hinges. Since ailerons control the aircraft's roll, hinge failure could cause loss of control. This directive prevents accidents by catching the defect early."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pzl-2-aileron-attach-hinges","history":"/api/acts/ad-pzl-2-aileron-attach-hinges/history","analysis":"/api/acts/ad-pzl-2-aileron-attach-hinges/analysis","conflicts":"/api/acts/ad-pzl-2-aileron-attach-hinges/conflicts","importantCases":"/api/acts/ad-pzl-2-aileron-attach-hinges/important-cases","documents":"/api/acts/ad-pzl-2-aileron-attach-hinges/documents"}}
