## Discrepancy

(CAN) ACFT WAS ENROUTE AT FL 260 WHEN THE CREW NOTICED A SLIGHT INCREASE IN CABIN RATE OF CLIMB. THE RATE CONTINUED FROM 500 FET PER MINUTE (FPM) TO A MAXIMUM OF 6000 FPM. THE CREW INITIATED AN EMERGENCY DESCENT AND LEVELED OFF AT 10,000 FEET. FLIGHT THEN DIVERTED TO THE CLOSEST AIRPORT AND LANDED WITHOUT FURTHER INCIDENT. THE ACFT WAS INSPECTED BY MX AND THE DOOR SEAL WAS FOUND TORN AND SUBSEQUENTLY REPLACED.
