Narrative:

The captain had just advised us 'ready for takeoff' and just as we were making the right turn to enter the runway for takeoff, flight attendant #4 detected a burning rubber odor. She sat at xa. I sat in xb. As the takeoff roll began, I began to smell the odor. Flight attendant #6 called flight attendant #1 to report the odor. It slowly dissipated. It was only on the right side of the cabin. A few mins later it returned. We searched for the source to no avail. It was decided to return to sju to have aircraft inspected. After 4 hours of searching, repressurizing the cabin and inspection, the aircraft was deemed safe to continue. I believe the odor probably originated outside the aircraft from an aircraft that was taxiing/taking off in front of us. What became unexplainable was why the odor returned. Could we have entered the same airspace as the previous aircraft and taken on the odor a second time? We were also operating under 1 air pack which could be why we only smelled it on the right side.

Title: CABIN ATTENDANT RPT, B767-200, SJU-JFK. ON TAXI, TKOF AND CLB. BURNING RUBBER FUMES ON R SIDE OF CABIN. RETURN TO SJU. 4 HR MAINT DELAY.

Narrative: THE CAPT HAD JUST ADVISED US 'READY FOR TKOF' AND JUST AS WE WERE MAKING THE R TURN TO ENTER THE RWY FOR TKOF, FLT ATTENDANT #4 DETECTED A BURNING RUBBER ODOR. SHE SAT AT XA. I SAT IN XB. AS THE TKOF ROLL BEGAN, I BEGAN TO SMELL THE ODOR. FLT ATTENDANT #6 CALLED FLT ATTENDANT #1 TO RPT THE ODOR. IT SLOWLY DISSIPATED. IT WAS ONLY ON THE R SIDE OF THE CABIN. A FEW MINS LATER IT RETURNED. WE SEARCHED FOR THE SOURCE TO NO AVAIL. IT WAS DECIDED TO RETURN TO SJU TO HAVE ACFT INSPECTED. AFTER 4 HRS OF SEARCHING, REPRESSURIZING THE CABIN AND INSPECTION, THE ACFT WAS DEEMED SAFE TO CONTINUE. I BELIEVE THE ODOR PROBABLY ORIGINATED OUTSIDE THE ACFT FROM AN ACFT THAT WAS TAXIING/TAKING OFF IN FRONT OF US. WHAT BECAME UNEXPLAINABLE WAS WHY THE ODOR RETURNED. COULD WE HAVE ENTERED THE SAME AIRSPACE AS THE PREVIOUS ACFT AND TAKEN ON THE ODOR A SECOND TIME? WE WERE ALSO OPERATING UNDER 1 AIR PACK WHICH COULD BE WHY WE ONLY SMELLED IT ON THE R SIDE.
