Took off as PNF; initial climb and gear retraction; normal. At about 500 ft PF gave me the aircraft and asked me to check my yoke trim switch my trim switch was inoperative; and the EICAS message 'ptrim main inoperative' appeared. I continued to fly the aircraft; straight ahead to 3000 ft; while using the back-up trim switch. PNF was coordinating with ATC; and running the pitch trim abnormal checklist. Aircraft required my full attention and both hands to work the yoke and backup trim switch. Checklist directed us to continue to our destination; which we proceeded to do. We discussed rvsm and fuel requirements to fly outside of rvsm airspace. During the climb my full attention was focused on the pfd to ensure safe aircraft control. During this time the PNF was coordinating with ATC and dispatch. During the climb; there were a number of ATC vectors; and center frequency changes. Upon leveloff; I noticed that the pitch attitude was different than normal and proceeded to figure out why. Looking at the EICAS; I recognized that the flaps were still at 9 degrees. Due to our proximity to the ground and our task saturation at the time; we fixated on the problem; and did not continue the climb checklist. Had either of us called acceleration altitude; the call would have been made for speed and flaps up; and the situation would not have occurred.

Title: EMB140 FLT CREW HAS EICAS WARNING MESSAGE 'PTRIM MAIN INOP;' PERFORMS QRH CHKLIST AND EXCEEDS FLAP SPD.
Narrative: TOOK OFF AS PNF; INITIAL CLB AND GEAR RETRACTION; NORMAL. AT ABOUT 500 FT PF GAVE ME THE ACFT AND ASKED ME TO CHK MY YOKE TRIM SWITCH MY TRIM SWITCH WAS INOP; AND THE EICAS MESSAGE 'PTRIM MAIN INOP' APPEARED. I CONTINUED TO FLY THE ACFT; STRAIGHT AHEAD TO 3000 FT; WHILE USING THE BACK-UP TRIM SWITCH. PNF WAS COORDINATING WITH ATC; AND RUNNING THE PITCH TRIM ABNORMAL CHKLIST. ACFT REQUIRED MY FULL ATTN AND BOTH HANDS TO WORK THE YOKE AND BACKUP TRIM SWITCH. CHKLIST DIRECTED US TO CONTINUE TO OUR DEST; WHICH WE PROCEEDED TO DO. WE DISCUSSED RVSM AND FUEL REQUIREMENTS TO FLY OUTSIDE OF RVSM AIRSPACE. DURING THE CLB MY FULL ATTN WAS FOCUSED ON THE PFD TO ENSURE SAFE ACFT CTL. DURING THIS TIME THE PNF WAS COORDINATING WITH ATC AND DISPATCH. DURING THE CLB; THERE WERE A NUMBER OF ATC VECTORS; AND CTR FREQ CHANGES. UPON LEVELOFF; I NOTICED THAT THE PITCH ATTITUDE WAS DIFFERENT THAN NORMAL AND PROCEEDED TO FIGURE OUT WHY. LOOKING AT THE EICAS; I RECOGNIZED THAT THE FLAPS WERE STILL AT 9 DEGS. DUE TO OUR PROX TO THE GND AND OUR TASK SATURATION AT THE TIME; WE FIXATED ON THE PROB; AND DID NOT CONTINUE THE CLB CHKLIST. HAD EITHER OF US CALLED ACCELERATION ALT; THE CALL WOULD HAVE BEEN MADE FOR SPD AND FLAPS UP; AND THE SIT WOULD NOT HAVE OCCURRED.
