## Discrepancy

DURING 100 HR INSPECTION, FOUND BOTH LT AND RT MLG PIVOT BUSHINGS SPLIT AND LEAKING GREASE.  THESE BUSHINGS ARE REQUIRED TO BE INSTALLED IAW AD2001-06-06, SB 90-1, SK 172-151.  THE SRM HAS NOT BEEN UPDATED TO SHOW ANY DETAIL OF THIS STYLE BUSHING.  NO INSPECTION PROCEDURES FOR THIS STYLE BUSHING.  PARTS MANUAL ALSO HAS NOT BEE UPDATED.  MUCH CONFUSION ABOUNDS CONCERNING THESE BUSHINGS.  (NM09200412026)
