The 421 (ST/A) Squadron pilot was making a low-level run-in to a target on the Suippes bombing range in France when he reported that he had control problems and was pulling up. Unable to control his aircraft, F/O L.B. Mealing safely ejected. The aircraft impacted at 45 degree dive and at 400 knots. The investigation board was unable to determine the cause, but suspected the yaw damper.
Several weeks later, another CF104 pilot experienced similar uncommanded control difficulties but he managed to land the aircraft. The investigation of the incident found that the hydraulic system was severely contaminated by metal filings. This contamination of the #1 system led to a hydraulic pump shaft failure while airborne. Following these two incidents, a successful stringent hydraulic fluid contamination control program was put in place by the RCAF to prevent such reoccurrences.
