## Discrepancy

(CAN) CREW ADVISED LOW NR 1 HYDRAULIC QTY AND WHEN THEY SELECTED FLAPS DOWN, THEY RECEIVED A NR 1 HYD ISO VALVE CAUTION AND THE FLAPS STAYED AT 0.  CREW CONDUCTED A FLAPLESS LANDING.  MAINTENANCE FOUND THE NR 1 ENGINE EDP PRESSURE LINE, PN 82970410-119,  AND CASE DRAIN RETURN LINE, PN 82970410-115, CHAFED ON EACH OTHER AND LEAKING. BOTH LINES ALONG WITH THE EDP WERE REPLACED,  ENGINE RUN AND LEAK CHECKED SERVICEABLE.
