Incident at Regina, SK

Summary

1997-05-08: NWT 664 was on final for Runway 31 at approximately 6 miles advising that they had flight control problems and were cancelling IFR, requesting a left 360 degree turn to rejoin final. When the a/c rejoined final approach, the pilot advised that the problem had been fixed. The a/c landed safely at 2142Z. Conditions were VFR, there was no damage, no operational impact. Visibility was 15 miles, ceiling 1600 broken, in class D and E airspace. UPDATE After the occurrence, the crew stated that they got a trailing edge flap asymmetry indication during flap selection on the first approach. The left flap was reading 25 degrees and the right flap was reading 15 degrees. No roll was encountered and as per the a/c checklist, they moved the flap handle to the smallest indicated position (15 degrees). Both flaps came up together and the crew reselected 25 degrees of flap and got a normal indication. On the ground, maintenance could not duplicate the problem and will be monitoring for similar problems in the future.
