This inspection must be done within 10 hours of flying time after 13 April 1977.\n\n**Who it affects:** Anyone who owns, operates, or maintains GAF N22 or N22B aeroplanes (these are Australian-designed agricultural and utility aircraft, often called \"Nomads\").\n\n**Why it matters:** Airworthiness Directives are legally binding safety instructions. If you don't comply, your aircraft is not considered airworthy — meaning you cannot legally fly it. This particular directive was triggered by a manufacturer alert (Service Bulletin N22.71.1) suggesting there may be a defect or wear issue in the engine intake area that could affect flight safety if not checked."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"Based on the text provided, the directive's scope is explicit and narrow: it applies to all GAF N22 and N22B models and requires inspection of the engine air intake fairing within 10 hours time in service after 13 April 1977 (Applicability; Compliance).
