Narrative:

During taxi out we were cleared to taxi to runway 8 after pushing back from gate. During taxi wbound on taxiway south our crew observed a B757 pushed back close to our taxiway. We thought we had enough clearance to taxi by so we proceeded slowly as captain and engineer looked out left side of aircraft to see the clearance. We taxied ahead about 50 yards and was informed by a captain of an A300 that we had touched the right rear horizontal stabilizer of the B757. We stopped the aircraft, contacted ground control and taxied back to the gate for inspection. Upon inspection we found that the outboard left leading edge scraped across the top of the horizontal stabilizer of the B757. Crew contacted chief pilot in nyc and maintenance control. FAA investigator showed up and took down all the particulars. Incident occurred at the north ramp area on taxiway south. Supplemental information from acn 399921: cleared by ground controller to taxi to holding point of runway 8. On taxiway south opposite to north ramp, 2 aircraft, 1 airbus and a B757, were pushed back from that ramp with an angle to taxiway south (this taxiway is parallel to north ramp). We slowed down and asked our flight engineer to assess the situation from the aft left cockpit window. He informed me it is clear. We passed the airbus but after passing the B757 which was the same distance with push back truck connected and more angled to taxiway south, the airbus captain reported to B757 on ground frequency that our wingtip hit the B757 horizontal stabilizer tip. Found minor damage on #1 leading edge flap which is very next to wingtip. Then went to B757 and found 2 static wicks missing and light marks. There were no tail walkers on ramp for pushback and no lines for north ramp and because of angle, the B757 horizontal stabilizer was in taxiway perimeter (our left wingtip hit right B757 elevator tip). We were on centerline of taxiway south at the time of incident. Supplemental information from acn 400027: north ramp tjsj. Aircraft was pushed back from gate at sju within the confines of the north ramp. Tug was disconnected, salute received. Both engines started when aircraft was struck from behind by a taxiing B747 on taxiway south. We had not yet released brakes and taxied under ship's power. The ramp was marked as to the location of our gear and the footprint of our wingtips. The aircraft was then towed back to the gate.

Title: THE WINGTIP OF A B747-200 TAXIING WBOUND ON TXWY S GRAZED THE R HORIZ STABILIZER OF A PUSHED BACK, HOLDING, B757-200 ON THE N RAMP AT SJU. PIC OF AN A300 RPTS INCIDENT ON GND CTL FREQ.

Narrative: DURING TAXI OUT WE WERE CLRED TO TAXI TO RWY 8 AFTER PUSHING BACK FROM GATE. DURING TAXI WBOUND ON TXWY S OUR CREW OBSERVED A B757 PUSHED BACK CLOSE TO OUR TXWY. WE THOUGHT WE HAD ENOUGH CLRNC TO TAXI BY SO WE PROCEEDED SLOWLY AS CAPT AND ENGINEER LOOKED OUT L SIDE OF ACFT TO SEE THE CLRNC. WE TAXIED AHEAD ABOUT 50 YARDS AND WAS INFORMED BY A CAPT OF AN A300 THAT WE HAD TOUCHED THE R REAR HORIZ STABILIZER OF THE B757. WE STOPPED THE ACFT, CONTACTED GND CTL AND TAXIED BACK TO THE GATE FOR INSPECTION. UPON INSPECTION WE FOUND THAT THE OUTBOARD L LEADING EDGE SCRAPED ACROSS THE TOP OF THE HORIZ STABILIZER OF THE B757. CREW CONTACTED CHIEF PLT IN NYC AND MAINT CTL. FAA INVESTIGATOR SHOWED UP AND TOOK DOWN ALL THE PARTICULARS. INCIDENT OCCURRED AT THE N RAMP AREA ON TXWY S. SUPPLEMENTAL INFO FROM ACN 399921: CLRED BY GND CTLR TO TAXI TO HOLDING POINT OF RWY 8. ON TXWY S OPPOSITE TO N RAMP, 2 ACFT, 1 AIRBUS AND A B757, WERE PUSHED BACK FROM THAT RAMP WITH AN ANGLE TO TXWY S (THIS TXWY IS PARALLEL TO N RAMP). WE SLOWED DOWN AND ASKED OUR FE TO ASSESS THE SIT FROM THE AFT L COCKPIT WINDOW. HE INFORMED ME IT IS CLR. WE PASSED THE AIRBUS BUT AFTER PASSING THE B757 WHICH WAS THE SAME DISTANCE WITH PUSH BACK TRUCK CONNECTED AND MORE ANGLED TO TXWY S, THE AIRBUS CAPT RPTED TO B757 ON GND FREQ THAT OUR WINGTIP HIT THE B757 HORIZ STABILIZER TIP. FOUND MINOR DAMAGE ON #1 LEADING EDGE FLAP WHICH IS VERY NEXT TO WINGTIP. THEN WENT TO B757 AND FOUND 2 STATIC WICKS MISSING AND LIGHT MARKS. THERE WERE NO TAIL WALKERS ON RAMP FOR PUSHBACK AND NO LINES FOR N RAMP AND BECAUSE OF ANGLE, THE B757 HORIZ STABILIZER WAS IN TXWY PERIMETER (OUR L WINGTIP HIT R B757 ELEVATOR TIP). WE WERE ON CTRLINE OF TXWY S AT THE TIME OF INCIDENT. SUPPLEMENTAL INFO FROM ACN 400027: N RAMP TJSJ. ACFT WAS PUSHED BACK FROM GATE AT SJU WITHIN THE CONFINES OF THE N RAMP. TUG WAS DISCONNECTED, SALUTE RECEIVED. BOTH ENGS STARTED WHEN ACFT WAS STRUCK FROM BEHIND BY A TAXIING B747 ON TXWY S. WE HAD NOT YET RELEASED BRAKES AND TAXIED UNDER SHIP'S PWR. THE RAMP WAS MARKED AS TO THE LOCATION OF OUR GEAR AND THE FOOTPRINT OF OUR WINGTIPS. THE ACFT WAS THEN TOWED BACK TO THE GATE.
