## Discrepancy

(CAN) APPROX 100PSI O2 LEAK OVERNIGHT. LOCATED LEAK AT BASE OF HOSE FITTING UNDER CO-PILOTS SIDE PANEL. FURTHER INVESTIGATION ALSO REVEALED THE HOSE WAS BULGING AT SAME LOCATION. ATTACHMENT POINT FOR THIS LINE IS TO THE `IN` PORT FITTING OF THE PASSENGER OXYGEN CONTROL PANEL PART #RCA73-06. REF MIDCOAST DWG#34-261F014 AND MIDCOAST SUPPLEMENTAL I.P.C. 35-20 PAGE 3 ITEM 127. IT SHOULD BE NOTED THAT RUPTURE OF THIS LINE IN FLIGHT WOULD CAUSE A DEPLETION OF THE O2 WITH NO MEANS OF TURNING OFF BOTTLES REMOTELY. (TC# 20190527011)
