JB E-190 Rudder

I caught this photo on 3/27/08 at MCO. When reviewing my photos, I noticed that the rudder on this aircraft did not match the paint scheme of the horizontal stabilizer. A rudder seems to be a strange part to have to swap out. Any ideas as to what may have been the reason to put a new rudder on this plane?

Thanks,
Steve

We caught that exact same plane at IAD on the 25th!! Rudders are actually pretty common to switch out, for a while Northwest had a 757-200 flying around with a rudder they borrowed/bought from UPS.
