## Discrepancy

THICK ACCURATE (ELECTRICAL/MECHANICAL SMELL) SMOKE COMING FROM THE VENTS IN THE CABIN AND FLIGHT DECK DURING CLIMBOUT. DEICED WITH TYPE 1 AND 4 PRIOR TO DEPARTURE. CAPTAIN SAID IT WASN’T DEICE FLUID SMELL. OCCURRED ON GEAR UP AROUND 700 FEET NOTICED SMOKE COMING FROM VENTS. APU WAS SUPPLYING BLEED. #1 AND #2 ENGINE BLEEDS WERE OFF. FLIGHT CREW DONNED O2 MASK.
