It required inspections of the main rotor blades. This requirement is now contained in manufacturer’s Handbook of Maintenance Instructions (HMI), Appendix B, so this AD is no longer required. |\n\n![](image.001.png)\n\nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n26 March 2009","sortOrder":0},{"sectionNumber":"AD/HU 269/11 Amdt 3","sectionType":"part","heading":"AD/HU 269/11 Amdt 3","content":"## AD/HU 269/11 Amdt 3","sortOrder":1},{"sectionNumber":"Main Rotor Blade - Inspection","sectionType":"part","heading":"Main Rotor Blade - Inspection","content":"## Main Rotor Blade - Inspection","sortOrder":2},{"sectionNumber":"5/2009","sectionType":"part","heading":"5/2009","content":"## 5/2009","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":1769},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This instrument terminates the Airworthiness Directive entirely rather than expanding its scope.

Since 1973, this rule had required operators of Schweizer (Hughes) 269 series helicopters to perform specific government-mandated inspections on main rotor blades.\n\n**Who it affects**\nOwners and operators of Schweizer (Hughes) 269 series helicopters, as well as maintenance engineers working on these aircraft.\n\n**Why it matters**\nPreviously, operators had to follow this specific government directive to check their rotor blades. Now, those same inspection requirements have been moved into the manufacturer's standard maintenance manual (the *Handbook of Maintenance Instructions*, Appendix B).\n\nBecause the safety checks are now covered by the manufacturer's normal instructions, this separate government directive is no longer needed. From 7 May 2009, operators simply follow the manufacturer's manual for these inspections rather than complying with this separate AD."}},"importantCases":[],"_links":{"self":"/api/acts/ad-hu-269-11-amdt-3-main-rotor-blade-inspection-cancelled","history":"/api/acts/ad-hu-269-11-amdt-3-main-rotor-blade-inspection-cancelled/history","analysis":"/api/acts/ad-hu-269-11-amdt-3-main-rotor-blade-inspection-cancelled/analysis","conflicts":"/api/acts/ad-hu-269-11-amdt-3-main-rotor-blade-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-hu-269-11-amdt-3-main-rotor-blade-inspection-cancelled/important-cases","documents":"/api/acts/ad-hu-269-11-amdt-3-main-rotor-blade-inspection-cancelled/documents"}}
