Narrative:

On an IFR flight plan from bkl, I was the PF and was given an IFR clearance to climb to 2000 ft, on a heading. This was a climb of about 1400 ft from the airport elevation after takeoff. During the climb out, we were given several heading changes after being handed off from the tower to approach control and at the same general time we were given a TA. We also received several messages at the same approximately time. While looking for traffic outside, I went 400-500 ft above my assigned altitude of 2000 ft for just a couple of seconds. I realized my mistake and instantly went back to 2000 ft. For a couple of seconds my mind could have wandered or I could have thought I was assigned a higher altitude, or I could have been looking at the view of the city. At any rate, I had a momentary mental lapse and should have been concentrating more on flying the airplane and my altitude. There were no traffic incursions or airspace violations, other aircraft were visual and the ground was not a factor. 2000 ft is too low to assign a jet aircraft for initial altitude.

Narrative: ON AN IFR FLT PLAN FROM BKL, I WAS THE PF AND WAS GIVEN AN IFR CLRNC TO CLB TO 2000 FT, ON A HDG. THIS WAS A CLB OF ABOUT 1400 FT FROM THE ARPT ELEVATION AFTER TKOF. DURING THE CLBOUT, WE WERE GIVEN SEVERAL HDG CHANGES AFTER BEING HANDED OFF FROM THE TWR TO APCH CTL AND AT THE SAME GENERAL TIME WE WERE GIVEN A TA. WE ALSO RECEIVED SEVERAL MESSAGES AT THE SAME APPROX TIME. WHILE LOOKING FOR TFC OUTSIDE, I WENT 400-500 FT ABOVE MY ASSIGNED ALT OF 2000 FT FOR JUST A COUPLE OF SECONDS. I REALIZED MY MISTAKE AND INSTANTLY WENT BACK TO 2000 FT. FOR A COUPLE OF SECONDS MY MIND COULD HAVE WANDERED OR I COULD HAVE THOUGHT I WAS ASSIGNED A HIGHER ALT, OR I COULD HAVE BEEN LOOKING AT THE VIEW OF THE CITY. AT ANY RATE, I HAD A MOMENTARY MENTAL LAPSE AND SHOULD HAVE BEEN CONCENTRATING MORE ON FLYING THE AIRPLANE AND MY ALT. THERE WERE NO TFC INCURSIONS OR AIRSPACE VIOLATIONS, OTHER ACFT WERE VISUAL AND THE GND WAS NOT A FACTOR. 2000 FT IS TOO LOW TO ASSIGN A JET ACFT FOR INITIAL ALT.
