Narrative:

Our flight from sjc to lax was a part 121 scheduled flight. I was not in the aircraft when the copilot received the clearance. We were issued a turn to 140 degrees on the clearance but when we took off with the copilot flying, we flew runway heading (300 degrees) bay departure asked if we had begun the turn and then issued a left turn to 140 degrees and an altitude of 3000 ft. Adding to the problem was the fact that I had not flown this route previously nor had I flown out of sjc for the last 5 yrs. Supplemental information from acn 413510: I copied the clearance at XA00 (turn left to 140 degrees, expect vectors to sns) for an XA30 departure. I went inside the terminal to get some lunch. Returned to the aircraft at XA20 and we taxied out at XA25. I hurried the departure as the PF, and stated we would get vectors to sns. Since the clearance was no longer fresh in my mind, and due to the relative simplicity of the clearance, I neglected to reread the clearance carefully, and forgot the turn after takeoff. Climbed straight out on runway 30L (300 degree heading) awaiting vectors. After 1 min, the departure controller asked us if we were in the turn. I immediately began the turn and the captain replied in the affirmative on the radio. The controller told us to 'keep it tight,' and maintain 3000 ft (originally assigned 7000 ft). I feel that the contributing factors were the length of time since copying the clearance (forgot an element) the simplicity of the clearance (no SID chart to pay attention to), and fatigue. We were on the last day (and the last leg) of a 4 day trip. First 2 overnights get in late (to the hotel at about XX00) and allow us to sleep in until about ZZ00. The last night we got in to las at about YY50 and woke up on the last day at XX00. This disruption in the sleep cycle made it difficult to sleep on the last night causing us to be quite tired on the last day.

Title: AFTER FO COPIED ATC CLRNC FOR SCHEDULED FLT FROM SJC TO LAX, HE LEFT THE ACFT AND WENT TO THE TERMINAL FOR A QUICK LUNCH. THE FO WAS PF AND AFTER DEP HE SHOULD HAVE TURNED L BUT WENT STRAIGHT AHEAD ON RWY HDG UNTIL QUESTIONED BY THE CTLR.

Narrative: OUR FLT FROM SJC TO LAX WAS A PART 121 SCHEDULED FLT. I WAS NOT IN THE ACFT WHEN THE COPLT RECEIVED THE CLRNC. WE WERE ISSUED A TURN TO 140 DEGS ON THE CLRNC BUT WHEN WE TOOK OFF WITH THE COPLT FLYING, WE FLEW RWY HDG (300 DEGS) BAY DEP ASKED IF WE HAD BEGUN THE TURN AND THEN ISSUED A L TURN TO 140 DEGS AND AN ALT OF 3000 FT. ADDING TO THE PROB WAS THE FACT THAT I HAD NOT FLOWN THIS RTE PREVIOUSLY NOR HAD I FLOWN OUT OF SJC FOR THE LAST 5 YRS. SUPPLEMENTAL INFO FROM ACN 413510: I COPIED THE CLRNC AT XA00 (TURN L TO 140 DEGS, EXPECT VECTORS TO SNS) FOR AN XA30 DEP. I WENT INSIDE THE TERMINAL TO GET SOME LUNCH. RETURNED TO THE ACFT AT XA20 AND WE TAXIED OUT AT XA25. I HURRIED THE DEP AS THE PF, AND STATED WE WOULD GET VECTORS TO SNS. SINCE THE CLRNC WAS NO LONGER FRESH IN MY MIND, AND DUE TO THE RELATIVE SIMPLICITY OF THE CLRNC, I NEGLECTED TO REREAD THE CLRNC CAREFULLY, AND FORGOT THE TURN AFTER TKOF. CLBED STRAIGHT OUT ON RWY 30L (300 DEG HDG) AWAITING VECTORS. AFTER 1 MIN, THE DEP CTLR ASKED US IF WE WERE IN THE TURN. I IMMEDIATELY BEGAN THE TURN AND THE CAPT REPLIED IN THE AFFIRMATIVE ON THE RADIO. THE CTLR TOLD US TO 'KEEP IT TIGHT,' AND MAINTAIN 3000 FT (ORIGINALLY ASSIGNED 7000 FT). I FEEL THAT THE CONTRIBUTING FACTORS WERE THE LENGTH OF TIME SINCE COPYING THE CLRNC (FORGOT AN ELEMENT) THE SIMPLICITY OF THE CLRNC (NO SID CHART TO PAY ATTN TO), AND FATIGUE. WE WERE ON THE LAST DAY (AND THE LAST LEG) OF A 4 DAY TRIP. FIRST 2 OVERNIGHTS GET IN LATE (TO THE HOTEL AT ABOUT XX00) AND ALLOW US TO SLEEP IN UNTIL ABOUT ZZ00. THE LAST NIGHT WE GOT IN TO LAS AT ABOUT YY50 AND WOKE UP ON THE LAST DAY AT XX00. THIS DISRUPTION IN THE SLEEP CYCLE MADE IT DIFFICULT TO SLEEP ON THE LAST NIGHT CAUSING US TO BE QUITE TIRED ON THE LAST DAY.
