Aircraft Equipment Problem Dissipated; Flight Crew Landed As Precaution; Flight Crew Overcame Equipment Problem; General Maintenance Action
Aircraft; Environment - Non Weather Related
On final approach with flaps 20 and gear down I asked for flaps 25 from FO. He moved handle and flaps did not move. They remained equal at 20 flaps and we got EICAS message 'TE FLAPS DISAG'. Being very confident that flaps were at 20 and that was ok for landing we checked flaps 20 ref speed and set approach speed accordingly. Completed the checklist and continued approach and landing. I made the decision to land based on altitude (approx 1200 AGL) at the time of event; CFIT risk high in that area and IFR conditions above 2000 feet; heavy traffic in area as well. Landing was the least risk decision. We noted the discrepancy in the AML and told MX and [Dispatch]. Landing was uneventful. There was no time to run QRH-simply accept the flight confuguration we currently had and that was sufficient for a safe landing. System malfunction. Repeat write up on this jet for same problem.I think the only other course of action would have been to go-around and run QRH which would have driven us to use ALT flap system. However; in that environment I think the safer course of action was to accept the flaps 20 setting and land. We had a very long runway and data to give us safe outcome. The unknowns in the go-around were higher risk. No way to prevent this-aircraft sysytem malfunction.
B757 Captain reported a flap malfunction and the subsequent decision to land without reference to the QRH.
