Narrative:

After normal pushback and 4 engine start; we were cleared to taxi from the ramp via taxiway a to runway 16; with clearance to cross runway 27(which was closed). The WX was good and the visibility was excellent. As we entered taxiway a northbound; I noticed that a B767 was parked on taxiway east; perpendicular to taxiway a and that the tail of the B767 was protruding into taxiway a. Given that taxiway east crossed taxiway a; and the large fillets on the east side where taxiway east intersected taxiway a; I felt that there was room to the right to comfortably move around the B767. I moved right and was monitoring the right wingtip spacing with the B767 tail. Once I felt that the right wingtip was clear of the B767 tail; I looked at the B767 right wing to assure clearance. At that time I turned back to the right. At no time did I feel that we were that close to the B767. Shortly thereafter; I felt the aircraft shudder slightly; which I assumed was from jetwash from the B767. Someone on the ATC ground frequency stated something like 'the 747 wingtip clipped the 767 tail.' I immediately stopped the aircraft; looked at the left wingtip and saw damage to the front of the winglet. We immediately shut down engines #1 and #2 in case there was fuel leaking. We then started the APU and shut down engines #3 and #4. After that; with no visible damage (ie; fuel leak); I called the purser to let her know what happened; and made an announcement to the passenger.

Title: B747-400 FLT CREW; WHILE TAXIING; HAS AN INADVERTENT COLLISION WITH ANOTHER ACFT.

Narrative: AFTER NORMAL PUSHBACK AND 4 ENG START; WE WERE CLRED TO TAXI FROM THE RAMP VIA TXWY A TO RWY 16; WITH CLRNC TO CROSS RWY 27(WHICH WAS CLOSED). THE WX WAS GOOD AND THE VISIBILITY WAS EXCELLENT. AS WE ENTERED TXWY A NBOUND; I NOTICED THAT A B767 WAS PARKED ON TXWY E; PERPENDICULAR TO TXWY A AND THAT THE TAIL OF THE B767 WAS PROTRUDING INTO TXWY A. GIVEN THAT TXWY E CROSSED TXWY A; AND THE LARGE FILLETS ON THE E SIDE WHERE TXWY E INTERSECTED TXWY A; I FELT THAT THERE WAS ROOM TO THE R TO COMFORTABLY MOVE AROUND THE B767. I MOVED R AND WAS MONITORING THE R WINGTIP SPACING WITH THE B767 TAIL. ONCE I FELT THAT THE R WINGTIP WAS CLR OF THE B767 TAIL; I LOOKED AT THE B767 R WING TO ASSURE CLRNC. AT THAT TIME I TURNED BACK TO THE R. AT NO TIME DID I FEEL THAT WE WERE THAT CLOSE TO THE B767. SHORTLY THEREAFTER; I FELT THE ACFT SHUDDER SLIGHTLY; WHICH I ASSUMED WAS FROM JETWASH FROM THE B767. SOMEONE ON THE ATC GND FREQ STATED SOMETHING LIKE 'THE 747 WINGTIP CLIPPED THE 767 TAIL.' I IMMEDIATELY STOPPED THE ACFT; LOOKED AT THE L WINGTIP AND SAW DAMAGE TO THE FRONT OF THE WINGLET. WE IMMEDIATELY SHUT DOWN ENGS #1 AND #2 IN CASE THERE WAS FUEL LEAKING. WE THEN STARTED THE APU AND SHUT DOWN ENGS #3 AND #4. AFTER THAT; WITH NO VISIBLE DAMAGE (IE; FUEL LEAK); I CALLED THE PURSER TO LET HER KNOW WHAT HAPPENED; AND MADE AN ANNOUNCEMENT TO THE PAX.
