## Discrepancy

DURING HIGH TIME ENGINE BEAM REPLACEMENT, UPON REMOVAL OF ENGINE BEAM A CRACK WAS VISUALLY IDENTIFIED ON THE INBOARD FACE OF THE RH INBOARD ENGINE BEAM. THIS CRACK IS EMANATING FROM A FASTENER LOCATION COMMON TO THE INBOARD VERTICAL CROSS OVER BEAM UPRIGHT (OEM: 5654107-15). THIS CRACK MEASURES APPROXIMATELY .025 INCHES LONG AND WAS HIDDEN BY THE UPRIGHT AS INSTALLED. THIS CRACK IS CONSISTENT WITH OTHER CRACKS FOUND ON RIGHT HAND INBOARD ENGINE BEAMS IN THIS AREA IN THE PAST.  PLEASE NOTE THAT THIS CRACK WAS NOT LOCATED IN THE LOCATION IDENTIFIED IN AD 97-26-16 OR AD 2015-07-03. THIS BEAM HAS BEEN REPLACED USING NEW PARTS.
