Narrative:

We were cleared for takeoff on runway 27 to climb and maintain 5000 ft with a right turn to 030 degrees. The copilot, being the PF, performed the takeoff. We were distracted immediately after takeoff by the controller advising another aircraft (the caravan), that he (the caravan), was not cleared for takeoff, that the takeoff clearance had been for another aircraft departing runway 27 (us). The controller then gave the caravan a heading of 270 degrees. At this time, realizing that the caravan had actually taken off by mistaking our clearance for himself, I was visually searching for him. We were in a climbing right turn off of runway 27 and if he had departed runway 36L, there could be a conflict/collision. Once wings level, I looked back at the flight instruments and we were at 5500 ft and still climbing. I advised the copilot who immediately returned to 5000 ft. The caravan was a contributing factor. The problem was the copilot's failure to concentrate on flying the airplane. Instead he let himself be distracted by the situation. We were not TCASII equipped, but to my knowledge there was no conflict. We never saw the other aircraft, and subsequent xmissions with ATC did not lead us to believe there was ever a conflict. To correct the problem: 1) basic airmanship of flcs. 2) require TCASII on all aircraft operated in class a, B, or C airspace.

Title: A CPR C550 FLC WAS DISTRACTED BY A C208 THAT TOOK OFF AT THE SAME TIME AS THEY DID, IN ERROR, FROM ANOTHER RWY AND THEY CLBED ABOVE THEIR ASSIGNED ALT WHILE LOOKING FOR THE C208.

Narrative: WE WERE CLRED FOR TKOF ON RWY 27 TO CLB AND MAINTAIN 5000 FT WITH A R TURN TO 030 DEGS. THE COPLT, BEING THE PF, PERFORMED THE TKOF. WE WERE DISTRACTED IMMEDIATELY AFTER TKOF BY THE CTLR ADVISING ANOTHER ACFT (THE CARAVAN), THAT HE (THE CARAVAN), WAS NOT CLRED FOR TKOF, THAT THE TKOF CLRNC HAD BEEN FOR ANOTHER ACFT DEPARTING RWY 27 (US). THE CTLR THEN GAVE THE CARAVAN A HDG OF 270 DEGS. AT THIS TIME, REALIZING THAT THE CARAVAN HAD ACTUALLY TAKEN OFF BY MISTAKING OUR CLRNC FOR HIMSELF, I WAS VISUALLY SEARCHING FOR HIM. WE WERE IN A CLBING R TURN OFF OF RWY 27 AND IF HE HAD DEPARTED RWY 36L, THERE COULD BE A CONFLICT/COLLISION. ONCE WINGS LEVEL, I LOOKED BACK AT THE FLT INSTS AND WE WERE AT 5500 FT AND STILL CLBING. I ADVISED THE COPLT WHO IMMEDIATELY RETURNED TO 5000 FT. THE CARAVAN WAS A CONTRIBUTING FACTOR. THE PROB WAS THE COPLT'S FAILURE TO CONCENTRATE ON FLYING THE AIRPLANE. INSTEAD HE LET HIMSELF BE DISTRACTED BY THE SIT. WE WERE NOT TCASII EQUIPPED, BUT TO MY KNOWLEDGE THERE WAS NO CONFLICT. WE NEVER SAW THE OTHER ACFT, AND SUBSEQUENT XMISSIONS WITH ATC DID NOT LEAD US TO BELIEVE THERE WAS EVER A CONFLICT. TO CORRECT THE PROB: 1) BASIC AIRMANSHIP OF FLCS. 2) REQUIRE TCASII ON ALL ACFT OPERATED IN CLASS A, B, OR C AIRSPACE.
