Narrative:

When flaps were selected from 15 to 5 degrees, aircraft yawed. While maintaining aircraft control, trimming and referencing the flap indicator it was determined that a split flap situation had occurred. ATC notified, priority was given. Crew referenced emergency procedures an uneventful landing was made. Cockpit resource management really works.
