THE LT MAIN GEAR WOULD NOT EXTEND WHEN THE PLT ATTEMPTED TO LOWER THE GEAR & AND THE ACFT WAS LANDED IN THAT CONDITION. AN EXAM OF THE STRUT ASSY REVEALED THAT A BEARING, P/N 5041108-1/2 HAD FAILED PERMITTING THE STRUT TO OVEREXTEND, JAMMING THE GEAR IN THE WHEEL WELL. A REVIEW OF FAILURE RECORDS REVEALED THAT OTHER SIMILIAR ACFT USING THIS BEARING HAD HAD SIMILIAR FAILURES RESULTING IN SIMILIAR ACCIDENTS.
