## Discrepancy

DEPARTED, ENROUTE (WITH 8 ON BOARD).  UPON REACHING FL410 AND AFTER APPROX 35 MINUTES IN FLIGHT, THE "PRESS SYS" LIGHT ILLUMINATED.  BEGINNING AN EMERGENCY DESCENT, IT WAS NOTED THAT THE `EMER PRESS` LIGHT HAD ALSO ILLUMINATED.  THE CABIN CLIMB WAS ARRESTED THEN BEGAN TO DESCEND DURING THE ACFT DESCENT.  ACFT DIVERTED AND THE WAS BROUGHT TO AN UNEVENTFUL AND SAFE LANDING.  AT THIS TIME PROBLEM WITH PRESSURIZATION IS UNDETERMINED.  ACFT IS BEING INSPECTED FOR OVERWEIGHT LANDING.  (K)
