## Discrepancy

DURING INSPECTION A CRACK WAS VISUALLY DISCOVERED ON THE INBOARD END OF THE LOWER CHANNEL OF THE RIGHT HAND CROSSOVER BEAM. THIS CRACK IS IN THE AREA OF THE MOUNTING HOLES FOR THE INBOARD EXHAUST ELBOW CLAMP BRACKET, AND MEASURES APPROXIMATELY 2 INCHES LONG AND IS CONSISTENT WITH OTHERS VISUALLY IDENTIFIED IN THIS AREA. THIS BEAM HAS BEEN REPLACED USING NEW PARTS.
