Narrative

WE GOT A R-HAND ENG OIL PRESSURE WARNING. ONCE ISSUED A TKOF CLRNC; I TAXIED ONTO THE RWY AND LINED UP ON THE CTRLINE. AT THAT MOMENT WE GOT A R-HAND ENG OIL LOW PRESSURE LIGHT. WE GOT CLRNC TO TAXI OFF THE RWY. AS WE TAXIED OFF THE WARNING LIGHT WENT AWAY. WITHIN A FEW SECONDS THE WARNING CAME BACK AND WE TOLD TWR WE NEEDED TO GO BACK TO THE GATE. AS WE TAXIED BACK THE FO RAN THE QRH FOR SAID INDICATION. ONCE HE WAS DONE HE CALLED THE STATION INFORMED THEM WE WERE RETURNING TO THE GATE. HE DID NOT GET AN ANSWER. WE WAITED FOR AN ANSWER BEFORE I DECIDED TO 'PARK MYSELF.' I SHUT DOWN THE R-HAND ENG PER THE QRH. I LEFT THE L-HAND RUNNING WAITING FOR ANYONE TO COME OUT AND CHOCK US. THE FO CALLED FEW MORE TIMES WITH NO RESPONSE. HE INFORMED ME THAT IT APPEARED WE WERE LOSING OIL OUT OF THE R ENG. I BECAME CONCERNED THAT IT WAS LEAKING AND COULD HIT A HOT SPOT AND START A FIRE. I ELECTED TO SHUT THE L ENG DOWN WITHOUT BEING CHOCKED AND NO STATION PERSONNEL ASSISTING US. I DID THIS IN CASE OF A FIRE AND I NEED TO EVAC. I HAD THE FLT ATTENDANT OPEN THE DOOR UNTIL STATION PERSONNEL ARRIVED. THE CABIN WAS GETTING VERY HOT AND I WAS STILL CONCERNED ABOUT LEAKING OIL CAUSING A FIRE. I SAW A RAMP PERSON LOADING A CRJ 20 YARDS AWAY. I LEFT THE ACFT WITH FO; SO I COULD GET THE RAMP PERSON AND QUICKLY INSPECT THE R-HAND ENG. I APCHED THE RAMP AGENT AND TOLD HIM I NEED TO GET THE ACFT CHOCKED AND GET MY PAX OFF THE ACFT RIGHT NOW. HE RESPONDED 'DUDE I'M LOADING BAGS AND WE ONLY HAVE 2 PEOPLE WORKING.' I WENT BACK TO THE PLANE MADE AN ANNOUNCEMENT TO THE PAX THAT THEY WOULD BE GETTING OFF THE ACFT IN A FEW MOMENTS. THE FO THEN LEFT TO GET CHOCKS AND CHOCK THE AIRPLANE HIMSELF. DURING THIS TIME OUR RAMP PERSONNEL WERE FOCUSED ON GETTING THE CRJ OUT DESPITE REPEATED CALLS; BOTH OVER THE RADIO AND IN PERSON; THAN HELPING US. I CALLED DISPATCH INFORMED HIM OF OUR SITUATION AND THE DISPATCHER SAID HE WOULD CALL THE STATION. ABOUT THIS TIME THE FO RETURNED WITH A RAMP AGENT GOT THE ACFT CHOCKED. I TOLD THE RAMP AGENT I WANTED THE PAX OFF THE ACFT NOW AND HE SAID I WOULD HAVE TO WAIT UNTIL THE CRJ TAXIED OUT. I DIDN'T ACCEPT THIS AND AT THAT TIME HE HELPED GET THE PAX OFF THE ACFT. I HAD TO WORK OUTSIDE SOP. 1) FAILURE TO ANSWER THE RADIO. 2) FAILURE TO PROVIDE ANY ASSISTANCE AFTER SEEING US RETURNING TO THE GATE. 3) FAILURE TO PROVIDE ASSISTANCE AFTER THE CAPT CONFRONTED A RAMP AGENT AND INFORMED HIM OF THE SITUATION. THEN TO HEAR 'DUDE I'M LOADING BAGS AND THERE'S ONLY TWO OF US OUT HERE.' 4) WANTING TO GET THE CRJ TAXIED OUT BEFORE LETTING MY PAX OFF THE 100 DEG ACFT. I FEEL THAT THIS SITUATION WAS HANDLED SO FAR 'OUT OF THE BOX' BECAUSE THE STATION WOULD NOT HELP US; AFTER CLRLY INFORMING THEM OF OUR SITUATION BY BOTH THE CAPT AND THE FO. WE AS A FLT CREW HAD TO WORK OUTSIDE OF SOP; PARKING WITHOUT A MARSHALLER; SHUTTING DOWN WITHOUT CHOCKS; ETC. MY ACTIONS WERE IN RESPONSE TO THE FACT I THOUGHT IF I HAD A FIRE DUE TO SUSPECTED LEAKING OIL I NEEDED TO GET MY PAX OFF THE ACFT AS SOON AS POSSIBLE.
