## Discrepancy

SB 500-27-004, REV B AILERON JOINT ASSY INSP AND REPLACEMENT.  THIS SB HAS PROCEDURES FOR INSPECTING/TESTING BOTH WINGS, AILERONS JOINT ASSEMBLIES.  REPLACING THE AILERON JOINT ASSY, WHENEVER THE AILERON FAILS A "FRICTION" TEST.  THE ASSY FAILS TESTING WHEN THE BELLCRANK IS CORRODED AND FROZEN IN THE BEARING OF THE FITTING ASSY.  THIS IS DUE TO CORROSION FROM DISSIMILAR METALS.  SINCE THIS IS JUST A SB, SUGGEST THIS INSP BE UPGRADED TO AN AD TO PREVENT POSSIBLE AILERON MALFUNCTIONS FROM ACFT NOT COMPLYING WITH THE SB.
