The \"closure collar\" is a component that helps secure the nosewheel assembly, and this directive mandates action to prevent potential failure during takeoff or landing.\n\n**Who it affects:** Owners and operators of Cessna 182 aeroplanes with serial numbers between 18261427 and 18261559 (approximately 133 specific aircraft).\n\n**What must be done:** Aircraft operators must complete the repair or inspection procedure described in Cessna Service Letter SE73-2, Item 1.
