## Discrepancy

(CAN) HYDRAULIC FLUID WAS NOTICED ROUND ACCESS PANEL 151CB RT. INVESTIGATION REVEALED A WEAR MARK AND PIN HOLE IN A HYDRAULIC LINE UNDER THE PANEL. FURTHER INVESTIGATION INDICATED THAT AN AJACENT PANEL BONDING STRAP HAD LOOPED WHEN THE PANEL WAS CLOSED AND HAD BEEN RUBBING ON THE HYDRAULIC LINE. THAT THE STRAP WOULD CHAFE ON THE HYDRAULIC LINE WAS NOT OBVIOUS WHEN THE PANEL WAS CLOSED. (TC NR 20070402002)
