What was found
DURING ANNUAL INSP, A CRACK WAS NOTED IN THE LOWER HORIZONTAL CROSSPIECE OF THE ENGINE MOUNT. THE CRACK IS APPROX .5000 INCH AWAY FROM THE PILOT SIDE END OF THIS TUBE, NEAR THE WELD THAT ATTACHES THIS TUBE TO THE DIAGONAL TUBE THAT ATTACHES TO THE FIREWALL LOWER PILOT SIDE SUPPORT BRACKET. THIS SAME CRACK LOCATION HAS BEEN SEEN IN SEVERAL AIRCRAFT. APPEARS TO BE A POINT OF HIGH VIBRATION INDUCED STRESS, AS THERE IS LITTLE LOAD ON THE PART DURING OPERATION.
