## Discrepancy

DURING ANNUAL INSPECTION CRACK WAS OBSERVED ON CONTROL COLUMN 1.0 INCHES LENGTH (49 MM).  CRACK WAS CONFIRMED BY MAGNETIC PARTICLE INSPECTION.  THE COMPONENT FORMS PART OF THE AC FLIGHT CONTROL SYSTEM AND IS CRITICAL TO FLIGHT.  BOTH THE LT AND RT FITTING ARE THE SAME PN.  PROBABLE CAUSE IS STRESS CORROSION CRACKING.  (EA35200501663)
