767 CONTROL RIGGING
Its not normal but it is quite common.If you were at 24a on a brand-new 767 you will most likely see the inboard ailerons nicely faired, however on very old models its common that the control rigging has not been kept up thus items like AILERONS and SPEED BRAKES can be in an un-faired state.The action of re-rigging is quite a specialised skill, takes time and money and many second/third tier operators cant be bothered with it but yes it does cost a lot of fuel.
