## Discrepancy

NR 2 ENG HAS INLET CONE FAIRING CRACKED AROUND BOLT HOLE.  *S/D*  THE CAUSE OF THE INLET CONE CRACKING IS VIBRATION OF THE INLET CONE FAIRING AGAINST THE INLET CONE SEATING.  THE MANUFACTURER ISSUED SERVICE BULLETIN V2500-ENG-72-0318 WHICH MODIFIED THE FAIRINGS WITH A SEAL TO REDUCE VIBRATION.  THIS SERVICE BULLETIN WAS IN PROCESS OF INCORPORATION BY COA R-9039-0/1.
