## Discrepancy

DURING MAINTENANCE A CRACK WAS VISUALLY IDENTIFIED ON THE RIGHT HAND CROSSOVER BEAM. THIS CRACK IS LOCATED ON THE AFT FACE OF THE BEAM, COMMON TO THE TOP OUTBOARD BOLT HOLE FOR THE TURBOCHARGER SUPPORT BRACKET. THIS CRACK MEASURES APPROXIMATELY .875 INCHES LONG TRAVELING LONGITUDINALLY ACROSS THE FASTENER LOCATION. IT IS CONSISTENT WITH OTHER CRACKS VISUALLY IDENTIFIED IN THIS AREA. THIS BEAM WILL BE REMOVED AND REPLACED.
