Incident at Vicinity of Empress, AB


1997-07-09: CDN 972 had departed Vancouver for Toronto when the crew noticed an unusual vibration of unknown origin. They decided to divert to Calgary where ERS was not called out, and the a/c landed without further incident. There were no delays for other a/c and the TSB has been advised. UPDATE The vibration felt by the crew was a strong shudder on the right side of the a/c. The crew attempted to alleviate the situation by alternating airspeed, without success. After consulting with company maintenance, it was decided to divert to Calgary. Examination of the a/c showed that the right elevator tab lockout mechanism had failed due to a bearing failure. The safety officer for the company said that this is a known deficiency.
