## Discrepancy

AIRCRAFT MADE A SCHEDULED DEPARTURE. DURING CLIMB OUT, SMOKE WAS NOTICED IN THE COCKPIT & CABIN BY BOTH THE FLIGHT CREW AND PASSENGERS. AIRCRAFT DECLARED AND EMERGENCY AND DIVERTED. AIRCRAFT LANDED WITHOUT INCIDENT. DURING INVESTIGATION AS TO THE CAUSE OF THE SMOKE, IT WAS DETERMINED THAT AN OIL SEAL IN THE APU HAD FAILED WHICH ALLOWED OIL INTO THE APU INTAKE CAUSING SMOKE IN THE CABIN.
