On a clear night, our IFR clearance was 'radar vectors to the gso 190 degree radial, 25 DME fix, as filed....' during the climb, we were cleared to 10000 ft. Shortly thereafter, our clearance was changed to 9000 ft. A few mins later we were given another radar vector (as we had received a number of headings earlier). Then we were cleared direct to the fix. In that we had expected radar vectors to the fix, it was not yet completely set up in the RNAV or long range navigation. While completing the fix setup, we climbed through 9000 ft to approximately 9300 ft. We corrected immediately and called visual contact with previously issued traffic. We were then cleared to 10000 ft. This altitude deviation occurred during a high workload (single pilot) segment of the flight when a clearance (direct to the fix) was not anticipated. No conflict occurred, but too much attention focused on 1 activity, caused less attention than appropriate to be paid to other duties.
Original NASA ASRS Text
Title: PLT OVERSHOT CLRNC ALT WHILE PROGRAMMING A FIX INTO RNAV.
Narrative: ON A CLR NIGHT, OUR IFR CLRNC WAS 'RADAR VECTORS TO THE GSO 190 DEG RADIAL, 25 DME FIX, AS FILED....' DURING THE CLB, WE WERE CLRED TO 10000 FT. SHORTLY THEREAFTER, OUR CLRNC WAS CHANGED TO 9000 FT. A FEW MINS LATER WE WERE GIVEN ANOTHER RADAR VECTOR (AS WE HAD RECEIVED A NUMBER OF HDGS EARLIER). THEN WE WERE CLRED DIRECT TO THE FIX. IN THAT WE HAD EXPECTED RADAR VECTORS TO THE FIX, IT WAS NOT YET COMPLETELY SET UP IN THE RNAV OR LONG RANGE NAV. WHILE COMPLETING THE FIX SETUP, WE CLBED THROUGH 9000 FT TO APPROX 9300 FT. WE CORRECTED IMMEDIATELY AND CALLED VISUAL CONTACT WITH PREVIOUSLY ISSUED TFC. WE WERE THEN CLRED TO 10000 FT. THIS ALTDEV OCCURRED DURING A HIGH WORKLOAD (SINGLE PLT) SEGMENT OF THE FLT WHEN A CLRNC (DIRECT TO THE FIX) WAS NOT ANTICIPATED. NO CONFLICT OCCURRED, BUT TOO MUCH ATTN FOCUSED ON 1 ACTIVITY, CAUSED LESS ATTN THAN APPROPRIATE TO BE PAID TO OTHER DUTIES.
