Narrative:

During climb out from lnk, I noticed that my GPS unit had failed. I had asked ZKC for some heading vectors to confirm that I was still headed in the right direction. Additionally, I asked for a higher altitude for my final altitude. The controller told me that I was indicating 7800 ft, 800 ft above my assigned altitude. I admitted that I was climbing at that time out of 7800 ft. ATC cleared me for 9000 ft. Simply put, I fixated my attention on a 'problem' and forgot to fly the plane.

Narrative: DURING CLBOUT FROM LNK, I NOTICED THAT MY GPS UNIT HAD FAILED. I HAD ASKED ZKC FOR SOME HDG VECTORS TO CONFIRM THAT I WAS STILL HEADED IN THE RIGHT DIRECTION. ADDITIONALLY, I ASKED FOR A HIGHER ALT FOR MY FINAL ALT. THE CTLR TOLD ME THAT I WAS INDICATING 7800 FT, 800 FT ABOVE MY ASSIGNED ALT. I ADMITTED THAT I WAS CLBING AT THAT TIME OUT OF 7800 FT. ATC CLRED ME FOR 9000 FT. SIMPLY PUT, I FIXATED MY ATTN ON A 'PROB' AND FORGOT TO FLY THE PLANE.
