2003-09-02: The Westjet Boeing 737-700, C-FKWS, was on approach to Regina, SK, when a go-around was initiated because of a flap asymmetry indication. The aircraft was levelled at 4000 ft asl and the flap asymmetry checks were completed. There were no abnormal control forces and normal flap indications were displayed. A second approach was attempted. On final approach, flaps 25 and flaps 30 were selected without corresponding flap movement and a second go-around was executed. ATC was advised that the aircraft would land with reduced flaps, but that CFR was not required. The crew ran the trailing edge non-normal checklist and a flaps 15 landing was completed. Maintenance carried out a bite test and were unable to duplicate the fault. The flaps functioned normally during the ground test.
