## Discrepancy

(CAN) ABOUT AN HOUR INTO THE FLIGHT, THE CREW RECEIVED A HYD 2 LOW CAUTION MESSAGE. THE NR 2 HYD SYS QTY WAS READING ZERO.  THE FLIGHT RETURNED TO THE DEPARTURE AIRPORT SAFELY.  INVESTIGATION FOUND A CHAFED HYD LINE IN THE CARGO COMPARTMENT AREA.  THE LINE WAS CHAFING AGAINST A BROKEN CLAMP ON AN ADJACENT LINE.

CLAMP, PN BBDREF001927143 (IPC 29-17-06, FIG 4A-480). ACFT TSN 19544, CSN 9848.
