## Discrepancy

THREE UPPER AIRSTAIR DOOR LATCHES FAILED TO PROPERLY LATCH AND CAUSED DOOR FRAME TO FAIL WHILE IN PRESSURIZED FLIGHT.  AIRCRAFT DE-PRESSURIZED AND THE PILOT RETURNED TO THE POINT OF DEPARTURE WITHOUT FURTHER INCIDENT.  SUSPECT FAILURE OF LATCHING MECHANISM PUSH ROD ATTACHMENT HARDWARE THAT PREVENTED ALL LATCH CAMS FROM FULLY ROTATING AND CAPTURING DOOR FRAME LUGS.
