## Discrepancy

AIRCRAFT FLYING AT 37,000 FEET.  LOST PRESSURIZATION.  MASK DROPPED AND AIRCRAFT DESCENDED.  PASSENGERS WERE ON BOARD. AIRCRAFT INSPECTED BY MAINTENANCE PERSONNEL FROM A CESSNA SERVICE CENTER AND NO PROBLEM COULD BE FOUND.  AIRCRAFT WAS FERRIED TO SERVICE CENTER.  FOUND SEVERAL SMALL LEAKS AND A SMALL HOLE IN THE DOOR SEAL.  SEALED THE LEAKS, REPLACED THE DOOR SEAL, AND BUILT THE DOOR FRAME UP TO GIVE THE SEAL A MORE POSITIVE SEAT.
