I believe it's one check per maneuver.
Say you have a fly speed of 40'. You want to go 10', turn 90° left (which uses 5' of movement), go 10', then turn 90° right (which also takes 5'), and finally go another 10'. That's two DC 15 checks. If you fail a check you're limited to the usual 45° turn for 5' of movement. If you passed the first and failed the second, you'd go 10', turn 90° for 5', go 10', turn 45° for 5', turn 45° for 5', then go 5' forward.
