Narrative:

The captain was talking to ATC and company operations on the ground, then we were climbing out of isp on radar vectors towards beads intersection -- our destination was atl. The last clearance we received stated to climb to 14000 ft and fly heading of either 180 degrees or 150 degrees, I forget. The controller had apparently said to climb to 4000 ft, which we both heard as 14000 ft. The captain who was the PNF read it back as 14000 ft. Needless to say, we almost collided with what I think was a small aircraft which was not equipped with TCASII, but thank god had an operating transponder. The resolution that our TCASII gave us on the vsi started out as first 'traffic,' then it showed a red arc on the vsi of about the area between 2000-3000 FPM, then the entire vsi, with the exception of the -1500 FPM and less went red. This is when I slammed the throttles to idle and put the nose aggressively over to descend. Our rate of climb when we first received an RA was about 3000 FPM. I learned a valuable lesson on readbacks that...ACARS would have helped since the captain...was also listening to the company while...ATC on the departure.

Title: A REGIONAL JET FLC CLBED ABOVE THE ASSIGNED ALT AND HAD AN NMAC ON DEP FROM ISP.

Narrative: THE CAPT WAS TALKING TO ATC AND COMPANY OPS ON THE GND, THEN WE WERE CLBING OUT OF ISP ON RADAR VECTORS TOWARDS BEADS INTXN -- OUR DEST WAS ATL. THE LAST CLRNC WE RECEIVED STATED TO CLB TO 14000 FT AND FLY HDG OF EITHER 180 DEGS OR 150 DEGS, I FORGET. THE CTLR HAD APPARENTLY SAID TO CLB TO 4000 FT, WHICH WE BOTH HEARD AS 14000 FT. THE CAPT WHO WAS THE PNF READ IT BACK AS 14000 FT. NEEDLESS TO SAY, WE ALMOST COLLIDED WITH WHAT I THINK WAS A SMALL ACFT WHICH WAS NOT EQUIPPED WITH TCASII, BUT THANK GOD HAD AN OPERATING XPONDER. THE RESOLUTION THAT OUR TCASII GAVE US ON THE VSI STARTED OUT AS FIRST 'TFC,' THEN IT SHOWED A RED ARC ON THE VSI OF ABOUT THE AREA BTWN 2000-3000 FPM, THEN THE ENTIRE VSI, WITH THE EXCEPTION OF THE -1500 FPM AND LESS WENT RED. THIS IS WHEN I SLAMMED THE THROTTLES TO IDLE AND PUT THE NOSE AGGRESSIVELY OVER TO DSND. OUR RATE OF CLB WHEN WE FIRST RECEIVED AN RA WAS ABOUT 3000 FPM. I LEARNED A VALUABLE LESSON ON READBACKS THAT...ACARS WOULD HAVE HELPED SINCE THE CAPT...WAS ALSO LISTENING TO THE COMPANY WHILE...ATC ON THE DEP.
