Human Factors
While taxiing from my hangar to the runway; I was distracted by programming my GNS 530W; and veered off the taxiway (a very dumb mistake). I then came in contact with a temporary sign used to advise non-pilots; the sign reads: 'No Vehicular Traffic Past this Point.' The prop made contact with the sign at idle speed and sliced it into 4 strips. The prop will now be overhauled to ensure safety. The prop RPM did not change when hitting the sign. I was the sole occupant; during this part 91 flight.This is clearly pilot error. My biggest takeaway is this: anytime the aircraft is moving; eyes are out the window. No excuses. Contributing factors include possible fatigue: this was my 5th flight of the day after waking up [early in the morning]. Also contributing factors: distraction in the cockpit by trying to program GPS while taxiing and pilot complacency by being overly confident in knowing the taxiway since I've done it hundreds of times. This will not happen again if I keep my eyes out of the window during taxi.
