This inspection must be completed within 100 hours of flight time after 28 December 1967, and then repeated at least every 100 hours of flight time thereafter.\n\n**Why it matters:** Cracks in this area could compromise the aircraft's structural integrity and control. Later model aircraft (PA-32-301 series) have a different wing design with a revised hinge structure, so this requirement only applies to the earlier models listed above."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-32-9-amdt-1-aileron-spar","history":"/api/acts/ad-pa-32-9-amdt-1-aileron-spar/history","analysis":"/api/acts/ad-pa-32-9-amdt-1-aileron-spar/analysis","conflicts":"/api/acts/ad-pa-32-9-amdt-1-aileron-spar/conflicts","importantCases":"/api/acts/ad-pa-32-9-amdt-1-aileron-spar/important-cases","documents":"/api/acts/ad-pa-32-9-amdt-1-aileron-spar/documents"}}
