Synopsis
Air carrier flight crew reported a ground conflict at GUM airport while holding short of the ramp area as another aircraft approached them at a high rate of speed. The Captain had to shout over the radio to the other crew to stop in order to avoid a collision.
Narrative
While on the Runway with another aircraft behind us (still was out past the FAF) Tower had given us instructions to clear the Runway on Taxiway F and then contact ramp. After clearing the Runway and on initial contact to ramp; they had told us to hold position as another aircraft was pushing back from Gate X (note could've been a nearby Gate). We had then notified ramp that we may need to make a right turn and taxi via G Runway 6L to J in order for the other aircraft to have full access to Taxiway K without having to cut through the Cargo ramp area. Ramp said standby for coordination. Roughly after a minute had pasted; the Aircraft Y called ramp for taxi and was cleared to taxi via K and contact ground. While taxing the other aircraft (Aircraft Y) continued to taxi on the K center line at a high rate of speed with their wing nearly making contact with the nose of our aircraft until the Captain got on the radios and told them to stop. In which they slammed on their brakes preventing imminent contact of our wings. After nearly 10 minutes of coordination a ground crew was able to push Aircraft Y back and we continued to the Gate uneventfully. Note; we had been sitting for roughly 5 minutes with the parking brake set prior to this event occurring. Our aircraft was well within the clear view of Aircraft Y and even after voicing our concerns with ramp nothing was done. It is in my believe that if the Captain hadn't gone on the radios to tell them stop there would've been an on the ground collision between the two aircraft with us having nowhere to go to avoid it.
Second reporter narrative
Tower cleared us to land on 6L. On short final another Company flight was cleared to land. As we were rolling out; Tower instructed us to exit on Taxiway F and to contact Ramp Control and we complied. As we were exiting on Taxiway F; we noticed an aircraft on Taxiway K on pushback. We cleared the Runway and contact Ramp Control. Ramp instructed us to Hold at Taxiway F; we complied. In the meantime; Company traffic behind us landed and exited on Taxiway J. While we were holding at 'F'; Ramp Control instructed Aircraft Y to contact Ground for Taxi clearance. We did not hear the Taxi instruction from Ground Control since we were on Ramp Control frequency. The next thing we observed was Aircraft Y started Taxi on Taxiway K. The intersection of 'F' and 'K' Taxiway cannot accommodate two airplanes. About six hundred yards from us; I contact ramp that we do not have room for Aircraft Y to pass by us safely. We did not get a response; so I took the initiative to contact Aircraft Y via Ramp frequency. I told them to 'Aircraft Y STOP'. They continue to taxi towards us now approaching really close to our aircraft; so I elevated the urgency to make them stop and I announced on the radio again 'Aircraft Y STOP; STOP; STOP'. They finally stop within I estimate a hundred feet. Their wingtip is about ten feet from the left cockpit window. Had they continue; their wingtip would have contact the Left Engine. At this point; I called Ramp Control and explained to them that both airplanes are too close to maneuver to prevent a collision. It took about thirty minutes to find a solution. Eventually; Aircraft Y was instructed to shutdown both engine and were told that they will be towed to a parking spot. Thereafter; we were cleared to Taxi for Gate XX. Made it to the Gate safely.
