## Discrepancy

FLIGHT CREW NOTICED AIRBRAKE HANDLE WAS STIFF AND HAD AN OCCASIONAL BIND.  TWICE THEY COULD NOT GET LIFT DUMP.  INVESTIGATION FOUND THE UPPER AND LOWER BEARINGS IN THE RIGHT AIRBRAKE BELLCRANK VERY ROUGH AND BINDING.  THESE BEARINGS ARE SEALED AND NO LUBRICATION REQUIRED.  POSSIBLE CAUSE IS TKS SOMEHOW GOT INTO THE BEARINGS CAUSING THEM TO CORRODE.
