These are small aircraft weighing less than 5,700 kg.\n\n**What must be done:** Aircraft operators must complete the inspection and modification within **100 hours of flight time** after 30 January 1976, following the technical instructions in Grumman American Service Bulletin No. 151.\n\n**Why it matters:** This prevents potential structural failure of the aircraft's centre spar, which could lead to loss of control during flight."}},"importantCases":[],"_links":{"self":"/api/acts/ad-aa-5-11-centre-spar-console-inspection-and-modification","history":"/api/acts/ad-aa-5-11-centre-spar-console-inspection-and-modification/history","analysis":"/api/acts/ad-aa-5-11-centre-spar-console-inspection-and-modification/analysis","conflicts":"/api/acts/ad-aa-5-11-centre-spar-console-inspection-and-modification/conflicts","importantCases":"/api/acts/ad-aa-5-11-centre-spar-console-inspection-and-modification/important-cases","documents":"/api/acts/ad-aa-5-11-centre-spar-console-inspection-and-modification/documents"}}
