Narrative:

We received a #2 bleed valve fail. Applied appropriate procedure and continued a climb clear of clouds/ice to FL290. Informed ATC upon check-in with ZNY that we would need to hold altitude until we could execute a fast descent to at or below 15000 ft to comply with our maintenance problem. Advised we could provide a 4000+ FPM descent to help them out if it would help. ATC said, 'fine, let me know when you are starting descent', cleared to 10000 ft by marrc intersection. We advised of the commencement of the descent and executed a 4500 FPM descent to 10000 ft to avoid a cloud level and reported icing about 14000 ft. As we passed through 13000 ft, we were xferred to the next controller. Earlier in-flight, before we advised of and were approved for the fast descent, were assigned 280 KTS for spacing into lga. Traffic on TCASII remained at 20 mi mark throughout descent but airspeed increased to 320 KTS to make the rate of descent work. As we checked on, ATC advised that our speed was excessive and asked why we were not at 280 KTS. We advised that we had cleared the high rate descent with the last controller and that we were slowing as we had just passed through the bases of the clouds. He advised that we were assigned 280 KTS and to get back to it. We clarified that we had been cleared by the last controller and had clarified the need. He explained that we were never told to accelerate.

Title: EMJ CREW HAD THE #2 PNEUMATIC BLEED VALVE FAIL. THEY HAD TO DSND INTO ICING CONDITIONS.

Narrative: WE RECEIVED A #2 BLEED VALVE FAIL. APPLIED APPROPRIATE PROC AND CONTINUED A CLB CLR OF CLOUDS/ICE TO FL290. INFORMED ATC UPON CHK-IN WITH ZNY THAT WE WOULD NEED TO HOLD ALT UNTIL WE COULD EXECUTE A FAST DSCNT TO AT OR BELOW 15000 FT TO COMPLY WITH OUR MAINT PROB. ADVISED WE COULD PROVIDE A 4000+ FPM DSCNT TO HELP THEM OUT IF IT WOULD HELP. ATC SAID, 'FINE, LET ME KNOW WHEN YOU ARE STARTING DSCNT', CLRED TO 10000 FT BY MARRC INTXN. WE ADVISED OF THE COMMENCEMENT OF THE DSCNT AND EXECUTED A 4500 FPM DSCNT TO 10000 FT TO AVOID A CLOUD LEVEL AND RPTED ICING ABOUT 14000 FT. AS WE PASSED THROUGH 13000 FT, WE WERE XFERRED TO THE NEXT CTLR. EARLIER INFLT, BEFORE WE ADVISED OF AND WERE APPROVED FOR THE FAST DSCNT, WERE ASSIGNED 280 KTS FOR SPACING INTO LGA. TFC ON TCASII REMAINED AT 20 MI MARK THROUGHOUT DSCNT BUT AIRSPD INCREASED TO 320 KTS TO MAKE THE RATE OF DSCNT WORK. AS WE CHKED ON, ATC ADVISED THAT OUR SPD WAS EXCESSIVE AND ASKED WHY WE WERE NOT AT 280 KTS. WE ADVISED THAT WE HAD CLRED THE HIGH RATE DSCNT WITH THE LAST CTLR AND THAT WE WERE SLOWING AS WE HAD JUST PASSED THROUGH THE BASES OF THE CLOUDS. HE ADVISED THAT WE WERE ASSIGNED 280 KTS AND TO GET BACK TO IT. WE CLARIFIED THAT WE HAD BEEN CLRED BY THE LAST CTLR AND HAD CLARIFIED THE NEED. HE EXPLAINED THAT WE WERE NEVER TOLD TO ACCELERATE.
