## Discrepancy

(CAN) SHORTLY AFTER DEPARTURE THE CREW NOTED ILLUMINATION OF THE RT HYDRAULIC LIGHT. A FEW SECONDS LATER THE LEFT HYDRAULIC LIGHT ILLUMINATED FOLLOWED BY A LOSS OF PRESSURE ON THE HYDRAULIC PRESSURE GAUGE.  THE AIRCRAFT RETURNED TO BASE AND LANDED UNEVENTFULLY. MAINTENANCE INSPECTION OF THE AIRCRAFT DETERMINED A LEAK IN THE HYDRAULIC PRESSURE LINE BETWEEN THE FIREWALL AND THE RIGHT SHUTOFF VALVE. THE LINE HAD DEVELOPED A CRACK ADJACENT TO THE SLEEVE AT THE FLARED END OF THE RIGID LINE AT THE FIREWALL. THERE WAS NO EVIDENCE OF PREVIOUS CHAFING OR DAMAGE TO THE AFFECTED LINE. THE LINE WAS REPLACED
