## Discrepancy

(CAN) DURING ROUTINE ISOTOPE INSPECTION A CRACK AND CORROSION WAS DETECTED IN THE LT ELEVATOR ACTUATOR ROD.  THE POSITION OF THE CRACK DID NOT SHEAR THE SECONDARY LOAD PATH AS 50 PERCENT OF THE THREADS REMAINED ENGAGED.  IF NEGLECTED THE CRACK WOULD HAVE RESULTED IN A CATASTROPHIC FAILURE.
