## Discrepancy

(CAN) DURING A SCHEDULED INSPECTION OF THE SEAT AS PER CMM 25-11-21 `CHECK 1`, THE SEAT BACK PIVOT SPINE SHAFT WAS DISCOVERED TO BE CRACKED AROUND THE CENTER BOLT HOLE. THIS CAUSED EXCESS PLAY OF THE SEAT BACK. THE CRACKED SHAFT WAS DISCOVERED DURING THE INSPECTION BUT IS NOT LISTED AS AN ITEM FOR INSPECTION UNDER `CHECK 1`. FURTHER EVALUATION OF THE CMM SHOWS THAT THE PIVOT SPINE SHAFT IS DUE FOR INSPECTION ON `CHECK 3`, WHICH HAS AN INTERVAL DUE AT THE AIRCRAFT `2C` CHECK. (TC# 20190508005)
