## Discrepancy

(CAN) DURING TAKEOFF, THE CREW WAS NOTIFIED THAT NR 3 WHEEL HAD SEPARATED FROM THE AIRCRAFT. THE BEARING HAD FAILED WHICH ALLOWED THE WHEEL ASSY TO PASS OVER THE RETENTION NUT AND SEPARATE.  DUE TO PAST ISSUES WITH BEARING FAILURES, A GREASE ANALYSIS HAS BEEN CONDUCTED SINCE MARCH 19, 2004 DUE TO ON GOING ISSUES WITH AEROSHELL 22 AND 5 WHEEL BEARING GREASE. OUR TEST INDICATED THAT A SWITCH TO MOBIL SHC100 IS IN ORDER AND THE FLEET WILL BE SWITCHED OVER EXPEDIOUSLY.
