## Discrepancy

FOUND SMOKE IN CABIN DURING FLIGHT.  SMOKE DISSIPATED BEFORE LANDING.  MAINTENANCE FOUND LEAKING OIL COOLER HOSE ON THE LT ENGINE, A SMALL AMOUNT OF OIL MIGRATED INTO THE ENVIRONMENTAL SYSTEM THAT CAUSED THE CABIN SMOKE.  THE OIL LINES WERE REPLACED AND IT TOOK A FEW ENGINE RUNS TO BURN THE RESIDUAL OIL FROM THE ENVIRONMENTAL SYSTEM.
