## Discrepancy

DURING TRANSIT CHECK AN HYDRAULIC LEAK WAS DETECTED ON LT ENGINE. DURING MAINTENANCE REVISION AN HYDRAULIC TUBE (P/N 316N3100-28) WAS DETECTED WITH DAMAGE. PROVISIONAL FLEXIBLE HOSE WAS INSTALLED, LEAK TEST WAS PERFORMED, NO LEAK WAS DETECTED. DURING OVERNIGHT SERVICE PROVISIONAL HOSE WAS REPLACED, LEAK TESTS WERE CORRECT.
