## Discrepancy

DURING THE PHASE 32, SENT THE ENGINE AND NACELLE TRUSSES OUT FOR NDI PER 5-14-22. THE ENGINE MOUNTS ARE NOT CALLED OUT FOR NDI INSPECTIONS DURING ANY PHASE. SENT THE ENGINE MOUNTS FOR NDI AS WELL THOUGH, DUE TO PREVIOUS FINDINGS OF CRACKS IN THE MOUNTS. IT WAS DETERMINED DURING NDI INSPECTION, THAT THE RT ENGINE OUTBOARD ENGINE MOUNT P/N: 5951048-2 HAD SHOWN A CRACK ACROSS THE WELD. THIS WOULD BE THE 3RD CRACKED ENGINE MOUNT FOUND DURING INSPECTIONS THIS YEAR. THERE ARE NO KNOWN SPECIAL INSPECTIONS FOR THESE MOUNTS. REF. PREVIOUS SDR CONTROL # 2026FA0000006 FOR PREVIOUS REPORT.
