What was found
DURING ROUTINE 100-HOUR ANNUAL INSPECTION, FOUND BOTH RT AND LT YOKE SUPPORTS CRACKED IN RADIUS OF BEND WHICH FROMS AFT FLANGE OF SUPPORT. THE CRACKS WERE QUITE SEVERE, ONE BEING COMPLETELY SEVERED, AND THE OTHER SIDE BEING VERY CLOSE TO SEVERED. THE CRACKS ARE IMPOSSIBLE TO SEE WITHOUT TILTING THE PILOT'S INSTRUMENT PANEL. CORRECTIVE ACTION CONSISTS OF REPLACING LT AND RT SUPPORTS WITH NEW UNITS. IT IS THE SUBMITTER'S OPINION THIS DAMAGE IS CAUSED BY THE TRANSFERRING OF LOADS FROM THE CONTROL LOCK ASSEMBLY.
