What was found
DURING ROUTINE 100-HOUR INSPECTION, FOUND BOTH RT AND LT YOKE SUPPORTS CRACKED IN RADIUS OF BEND WHICH FORMS AFT FLANGE OF SUPPORT. THE CRACKS WERE QUITE SEVERE, ONE SIDE 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. CORRECTION 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.
