Narrative:

After dropping off my passengers at fort dodge, ia, my company redispatched me to pick up some cargo at columbus, northeast. The freight needed to arrive in minneapolis as soon as possible. After checking WX and filing an IFR flight plan, I preflted my aircraft and taxied out for departure. The WX was VFR with scattered to broken clouds around 1500 AGL. I received a clearance to depart runway 06 climb and maintain 3000. I wrote down the runway heading (which I do not normally do) squawk and departure frequency adding the runway heading where I normally write my altitude. An small aircraft departed ahead of me and turned left along my flight path. Unfortunately, it appeared he wasn't maintaining legal cloud separation. I was concerned about the VFR traffic. Being distracted by him, as well as copying my clearance incorrectly, I climbed through my assigned altitude of 3000. ATC advised me of my mistake and I quickly descended to the appropriate altitude. I learned to be consistent in copying clearance (I now use a form). Do not rush. No trip is as important as operating my aircraft legally and safely. Had I waited with my departure, the small aircraft would not have been a traffic factor (irregardless of his visual separation). I will not add to the mistake of others.

Title: SINGLE PLT IFR IN TWIN FREIGHTER OVERSHOT ASSIGNED ALT IN CLB.

Narrative: AFTER DROPPING OFF MY PAXS AT FORT DODGE, IA, MY COMPANY REDISPATCHED ME TO PICK UP SOME CARGO AT COLUMBUS, NE. THE FREIGHT NEEDED TO ARRIVE IN MINNEAPOLIS ASAP. AFTER CHKING WX AND FILING AN IFR FLT PLAN, I PREFLTED MY ACFT AND TAXIED OUT FOR DEP. THE WX WAS VFR WITH SCATTERED TO BROKEN CLOUDS AROUND 1500 AGL. I RECEIVED A CLRNC TO DEPART RWY 06 CLB AND MAINTAIN 3000. I WROTE DOWN THE RWY HDG (WHICH I DO NOT NORMALLY DO) SQUAWK AND DEP FREQ ADDING THE RWY HDG WHERE I NORMALLY WRITE MY ALT. AN SMA DEPARTED AHEAD OF ME AND TURNED L ALONG MY FLT PATH. UNFORTUNATELY, IT APPEARED HE WASN'T MAINTAINING LEGAL CLOUD SEPARATION. I WAS CONCERNED ABOUT THE VFR TFC. BEING DISTRACTED BY HIM, AS WELL AS COPYING MY CLRNC INCORRECTLY, I CLBED THROUGH MY ASSIGNED ALT OF 3000. ATC ADVISED ME OF MY MISTAKE AND I QUICKLY DSNDED TO THE APPROPRIATE ALT. I LEARNED TO BE CONSISTENT IN COPYING CLRNC (I NOW USE A FORM). DO NOT RUSH. NO TRIP IS AS IMPORTANT AS OPERATING MY ACFT LEGALLY AND SAFELY. HAD I WAITED WITH MY DEP, THE SMA WOULD NOT HAVE BEEN A TFC FACTOR (IRREGARDLESS OF HIS VISUAL SEPARATION). I WILL NOT ADD TO THE MISTAKE OF OTHERS.
