## Discrepancy

(AIRCRAFT NOT GROUNDED) DURING DESCENT CABIN PRESSURE DIDN'T CHANGE, AT 14000 FEET WE HAD A 6000 FEET CABIN PRESSURE, SWITCHED CONTROLLERS WITH NO EFFECT IN CABIN PRESSURE. WE HAD TO USE MANUAL CONTROLLER TO DEPRESSURIZE THE CABIN. / PERFORMED BITE TEST OF CPC1 AND CPC2 IAW AMM 21-31-00-710-002-A. TEST OK."
