## Discrepancy

(CAN) RETURNING HOME AT CRUISE ALTITUDE, THE PILOT NOTICED INDICATED FLUID LEVEL DROPPING, THEN WARNING INDICATION. EMERGENCY DECLARED AND LANDED WITHOUT FURTHER INCIDENT.  UPON INVESTIGATION, IT WAS DISCOVERED THAT THE HYD NR 1 SYS PRESSURE LINE FROM PRESSURE MANIFOLD TO ENGINE FIREWALL WAS CHAFED THROUGH AS A RESULT OF AN HOSE CLAMP FROM ANOTHER LINE RUBBING AGAINST IT.
