## Discrepancy

THE CABIN AND COCKPIT FILLED WITH SMOKE WHILE IN CRUISE AT 37,000 FT, EN ROUTE FROM SJC TO IAH.  EMERGENCY PROCEDURES WERE COMPLIED WITH AND THE AIRCRAFT WAS DIVERTED TO SAT WHERE IT LANDED SAFELY.  MAINTENANCE FOUND COOLING FAN WHERE IT ATTACHES TO GEARBOX LEAKING OIL.  THE APU WAS REMOVED AND REPLACED IAW WORK CARD 08-4900-1-0002.  IN ADDITION, BOTH AC PACK COALESCER BAGS WERE REMOVED AND REPLACED IAW MM 21-20-02.  OPERATIONAL CHECKS WERE GOOD.
