If the valve fails in flight, the engine could be starved of fuel even when tanks contain plenty of fuel — potentially causing engine failure and a forced landing.\n\n**Who must act:**\nAnyone who owns, operates, or maintains an ATL or ATL \"S\" series Robin aircraft.\n\n**What they must do:**\n- **By 22 May 1992:** Complete the first inspection following the technical instructions in a French aviation safety document (DGAC AD 88-050(A)).\n- **After that:** Re-inspect the valve every 50 hours of flight time (\"time in service\" means actual flying hours, not time parked on the ground).\n\n**Key point:** This isn't optional. Airworthiness Directives are legally binding. Flying without complying can ground an aircraft or invalidate its certificate of airworthiness."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The instrument applies to \"All ATL and ATL\"S\" Series Robin aircraft\" and requires repetitive inspection of the fuel selector valve per the referenced DGAC AD.
