## Discrepancy

WE HAVE FOUND A SCISSOR LINK, H-BLOCK, DURING ALF INSPECTION TO HAVE DISBONDED BUSHINGS. THIS IS A LOW HOUR SCISSOR LINK, AND THERE MAY BE A ISSUE WITH THE REPAIRS BEING PERFORMED ON THESE LINKS.  POSSIBLE CAUSE IS THE BUSHING SPECIFICATIONS DO NOT MEET THE STANDARD OF THE ACTUAL LINK IT IS BEING PRESSED INTO AS FAR AS IT DIMENSIONS.  OR THE ADHESIVE OR BONDING AGENT DOES NOT MEET THE STANDARD OF ADHERING THE BUSHING TO THE BLOCK.  THE LAST O/H ON THIS BLOCK WAS PERFORMED.  THE O/H WAS IAW.  R & R 4 BUSHINGS.
