## Discrepancy

DURING TAKEOFF FROM MKE THE AIRCRAFT FILLED WITH SMOKE IN BOTH THE CABIN AND COCKPIT.  THE FLIGHT CREW ABORTED THE TAKEOFF.  THE AIRCRAFT WAS FERRIED TO MSP, THE ODOR RETURNED BUT NO SMOKE.  THE NUMBER ONE ENGINE 13TH STAGE HYDRAULIC RESERVOIR CHECK VALVE WAS FOUND TO HAVE FAILED.  REMOVED AND REPLACED BOTH NR 1 AND NR 2 CHECK VALVES AND BOTH COALESOR BAGS.  RAN ALL THREE ENGINES AT DIFFERENT POWER SETTINGS SEVERAL TIMES, NO FURTHER FAULT FOUND.
