What was found
THE BUCKLES ON THE LAP BELTS OF THIS AIRCRAFT BECAME DIFFICULT/IMPOSSIBLE TO LATCH. CALLED MFG AND BELT SUPPLIER AND THEY KNEW OF THE PROBLEM AND FURNISHED US WITH NEW BELT ASSEMBLIES ASAP. ACFT MFG/SUPPLIER SHOULD HAVE BEEN PRO-ACTIVE INSTEAD OF REACTIVE ON THIS, DUE TO THE CRITICAL NATURE OF THE BUCKLES.
