## Discrepancy

WHILE WASHING AC, SCRUB BRUSH NOCKED OFF NUT AND ENGAGED PORTION OF ONE OF THE (AN4-11A) BOLTS THAT SECURES THE RT MLG ASSY TO THE RT WING.  BOLT WAS CORRODED ALL THE WAY ACROSS ITS CROSS SECTION.  SUGGESTIONS: PERIODICALLY CHECK TORQUE ON THESE BOLTS TO ENSURE BOLT NOT CORRODED THROUGH LIKE THIS ONE.  REPLACE THES BOLTS PERIODICALLY TO PRECLUDE CORROSION FAILURE.  (K)
