## Discrepancy

RT LANDING GEAR FAILED TO FULLY EXTEND AND LOCK.  THE RT DOWNLOCK PN 5041018-1 SEIZED DUE TO LACK OF LUBRICATION. THE DOWN LOCK ROD END PN KWBS WAS ALSO SEIZED FOR THE SAME REASON.  THE WEIGHT OF THE ACFT ON THE PARTIALLY EXTENDED GEAR PULLED THE BELLCRANK BRACKETS, PN 0811302-1 AND 0811303-1, FRON THE CTR FRONT SPAR, LOCATED TO THE RIGHT OF THE LANDING GEAR, GEAR BOX.(SHEARED THE ATTACH RIVETS) THERE IS A GEAR INSP REQUIREMENT IN THE MM WITH LUBRICATION REQUIREMENTS THAT SHOULD BE ACCOMPLISHED ANNUALLY.
