Narrative:

In pal-waukee airport I attempted to do a 180 degree turn to back taxi to a taxiway when my right main gear went off the side of the runway and sank in very soft mud. I must have misunderstood tower's instructions to taxi to the end. Perhaps I was a little rattled by my bad landing and thought they (tower) meant the taxiway I had just passed. I didn't realize there was a taxiway at the end of the runway. I was given a choice of runways, runway 6 being the most favorable because of winds, but was shorter, but still very sufficient in length, however, quite narrow. I should have taxied further to one side of the runway before turning or continued to the end as instructed by ATC. I feel that runway 6 in pwk should not be a choice for twins because of obstruction (power lines) right at the end. It should also be notamed that the ground is very soft although it doesn't appear to be.

Title: RWY EXCURSION AFTER A HARD LNDG. NON ADHERENCE TO ATC INSTRUCTION.

Narrative: IN PAL-WAUKEE ARPT I ATTEMPTED TO DO A 180 DEG TURN TO BACK TAXI TO A TXWY WHEN MY R MAIN GEAR WENT OFF THE SIDE OF THE RWY AND SANK IN VERY SOFT MUD. I MUST HAVE MISUNDERSTOOD TWR'S INSTRUCTIONS TO TAXI TO THE END. PERHAPS I WAS A LITTLE RATTLED BY MY BAD LNDG AND THOUGHT THEY (TWR) MEANT THE TXWY I HAD JUST PASSED. I DIDN'T REALIZE THERE WAS A TXWY AT THE END OF THE RWY. I WAS GIVEN A CHOICE OF RWYS, RWY 6 BEING THE MOST FAVORABLE BECAUSE OF WINDS, BUT WAS SHORTER, BUT STILL VERY SUFFICIENT IN LENGTH, HOWEVER, QUITE NARROW. I SHOULD HAVE TAXIED FURTHER TO ONE SIDE OF THE RWY BEFORE TURNING OR CONTINUED TO THE END AS INSTRUCTED BY ATC. I FEEL THAT RWY 6 IN PWK SHOULD NOT BE A CHOICE FOR TWINS BECAUSE OF OBSTRUCTION (POWER LINES) RIGHT AT THE END. IT SHOULD ALSO BE NOTAMED THAT THE GND IS VERY SOFT ALTHOUGH IT DOESN'T APPEAR TO BE.
