## Discrepancy

LEFT AND RIGHT ELEVATORS, DISASSEMBLED FOR REPAIR. WHEN INBD FLANGE, WAS REMOVED, EXFOLIATING CORROSION WAS FOUND ON SPAR.  CORROSION IS LOCATED UNDER FLANGE ATTACH TO SPAR. THIS IS NOT VISIBLE UNTIL PARTS ARE DISASSEMBLED.  THIS IS NOT A FLIGHT TIME ISSUE, BUT IS A CALENDER TIME ISSUE.
