Flight Crew Overcame Equipment Problem; General Maintenance Action
Human Factors; Company Policy; Procedure
In an effort to use all the center tank fuel; I turned on one pump and opened the crossfire valve. I subsequently failed to close the valve. The differential main pump pressure caused a 3;000 pound imbalance between the main tanks. The First Officer (Pilot Flying) noticed the imbalance on final approach. We landed with the imbalance. I notified Maintenance of the discrepancy and; after consultation with Maintenance Control and the inspection procedures; the decision was made to remove the aircraft from service.
A 737 flight crew inadvertently left a fuel cross feed valve open. This resulted in a significant fuel imbalance; which was discovered during final approach. The crew elected to land with the imbalance; resulting in a post flight inspection and maintenance action.
