Narrative:
My departure clearance from sdl was the banyo 4 departure, radar vectors to V567 to winslow, az (INS), maintain 5000 ft, expect 17000 ft in 3 mins. I continued runway heading when I took off. I should have turned left to 260 degrees to intercept the departure on my own, but didn't. I thought I would get a vector to intercept the departure route, but should have turned to 260 degrees on my own to intercept the departure assigned. I feel that the good VFR conditions caused me to be lax in studying, and properly executing, the clearance as it should have been. This was a great error on my part. Although there were no immediate dangers this time, if the WX had been bad and I would have had an engine failure, there could have been terrain problems. Maybe the heading should be given in a clearance like this when the departure was issued, although I realize that it is the pilot's responsibility to properly study the routing. Should the tower visually or verbally assure the aircraft has made the turn? As many safeguards as possible, would surely be good. Got a vector back on course.

Title: A C441 SINGLE PLT MISUNDERSTOOD HIS CLRNC, COMMITTING A HDG TRACK DEV IN P50'S AIRSPACE.
Narrative: MY DEP CLRNC FROM SDL WAS THE BANYO 4 DEP, RADAR VECTORS TO V567 TO WINSLOW, AZ (INS), MAINTAIN 5000 FT, EXPECT 17000 FT IN 3 MINS. I CONTINUED RWY HDG WHEN I TOOK OFF. I SHOULD HAVE TURNED L TO 260 DEGS TO INTERCEPT THE DEP ON MY OWN, BUT DIDN'T. I THOUGHT I WOULD GET A VECTOR TO INTERCEPT THE DEP RTE, BUT SHOULD HAVE TURNED TO 260 DEGS ON MY OWN TO INTERCEPT THE DEP ASSIGNED. I FEEL THAT THE GOOD VFR CONDITIONS CAUSED ME TO BE LAX IN STUDYING, AND PROPERLY EXECUTING, THE CLRNC AS IT SHOULD HAVE BEEN. THIS WAS A GREAT ERROR ON MY PART. ALTHOUGH THERE WERE NO IMMEDIATE DANGERS THIS TIME, IF THE WX HAD BEEN BAD AND I WOULD HAVE HAD AN ENG FAILURE, THERE COULD HAVE BEEN TERRAIN PROBS. MAYBE THE HDG SHOULD BE GIVEN IN A CLRNC LIKE THIS WHEN THE DEP WAS ISSUED, ALTHOUGH I REALIZE THAT IT IS THE PLT'S RESPONSIBILITY TO PROPERLY STUDY THE ROUTING. SHOULD THE TWR VISUALLY OR VERBALLY ASSURE THE ACFT HAS MADE THE TURN? AS MANY SAFEGUARDS AS POSSIBLE, WOULD SURELY BE GOOD. GOT A VECTOR BACK ON COURSE.
