Incident at Calgary, Alberta


1996-12-16: The Boeing 737 was on final approach to runway 34 at Calgary. At about 1,500 feet AGL, the First Officer commented that the aircraft did not feel right. The captain took control and felt a dead spot in the pitch control fore and aft of neutral, and very heavy stick forces outside of the dead spot. The roll control was also extremely heavy. The First Officer completed the landing. During the flare, the stick force was extremely heavy and effected little pitch change. The control column was well aft of the normal position of the flare. The flight controls were cycled several times during taxi and felt very heavy. The feel differential pressure light cycled on and off while the flight controls were being moved on the ground. Maintenance performed visual and functional checks on all flight control and hydraulic systems. The elevator feel computer and elevator feel pitot system were also checked. The hydraulic case drain filters were removed and examined, and new filters were installed. No discrepancies were identified. The aircraft was flight tested and returned to service.
