It requires owners or operators of **Call Air A-9 series aeroplanes** to check the main landing gear attachment points for cracks.\n\nSpecifically, you must inspect the welded areas of wing-to-fuselage struts with part numbers 10915-1 and 10915-2. These inspections must happen **every 100 hours of flight time** (calculated as \"time in service\") starting from 1 September 1971.\n\nThe purpose is to detect fatigue cracking in the welded joints before they lead to landing gear failure, which could cause an accident during takeoff or landing."}},"importantCases":[],"_links":{"self":"/api/acts/ad-ac-cla-3-main-landing-gear-attachment","history":"/api/acts/ad-ac-cla-3-main-landing-gear-attachment/history","analysis":"/api/acts/ad-ac-cla-3-main-landing-gear-attachment/analysis","conflicts":"/api/acts/ad-ac-cla-3-main-landing-gear-attachment/conflicts","importantCases":"/api/acts/ad-ac-cla-3-main-landing-gear-attachment/important-cases","documents":"/api/acts/ad-ac-cla-3-main-landing-gear-attachment/documents"}}
