Narrative:

On oct/tue/03, starting at approximately XA30 I started my inspection of the right hand engine of aircraft X per card XXXX and other work cards. I completed my inspection that evening and did not find any discrepancies in the ogv line segment area. The following am the aircraft was run up to accomplish leak and operations check by late night management personnel, and then later taken to the gate. At the gate, someone found the ogv liner segment 'acoustical panel' damaged. In the future, I will give closer attention to these panels since I was informed there was a problem in this area. I don't know what contributed to the damage found, but I inspected the area and there was no damage noted at the time. I suspect that something happened either during the run-up or the taxi to the gate, possibly foreign object damage on the ramp, that caused the damage.

Title: A B767-200 RELEASED FROM HVY MAINT AFTER ENG INSPECTIONS AND WAS FOUND TO HAVE #2 ENG OUTER GUIDE VANE ACOUSTICAL PANEL DAMAGE.

Narrative: ON OCT/TUE/03, STARTING AT APPROX XA30 I STARTED MY INSPECTION OF THE R HAND ENG OF ACFT X PER CARD XXXX AND OTHER WORK CARDS. I COMPLETED MY INSPECTION THAT EVENING AND DID NOT FIND ANY DISCREPANCIES IN THE OGV LINE SEGMENT AREA. THE FOLLOWING AM THE ACFT WAS RUN UP TO ACCOMPLISH LEAK AND OPS CHK BY LATE NIGHT MGMNT PERSONNEL, AND THEN LATER TAKEN TO THE GATE. AT THE GATE, SOMEONE FOUND THE OGV LINER SEGMENT 'ACOUSTICAL PANEL' DAMAGED. IN THE FUTURE, I WILL GIVE CLOSER ATTN TO THESE PANELS SINCE I WAS INFORMED THERE WAS A PROB IN THIS AREA. I DON'T KNOW WHAT CONTRIBUTED TO THE DAMAGE FOUND, BUT I INSPECTED THE AREA AND THERE WAS NO DAMAGE NOTED AT THE TIME. I SUSPECT THAT SOMETHING HAPPENED EITHER DURING THE RUN-UP OR THE TAXI TO THE GATE, POSSIBLY FOREIGN OBJECT DAMAGE ON THE RAMP, THAT CAUSED THE DAMAGE.
