Narrative:

Air carrier X departed las from runway 01. Passing approximately 7000' departure control asked if a turn had been commenced. The PNF indicated that the turn to 300 degrees had been completed. Departure instructed an immediate turn to 200 degrees, then further to 180 degrees. The departure controller indicated that the heading should have been to 200 degrees versus 300 degrees. The flight was subsequently turned to a 270 degree heading to intercept the arwy to bty. There was no indication of traffic alert/conflict or requirement to reroute air traffic. Subsequent discussions were conducted by phone with the las tower radar supervisor. He indicated that he had listened to the tapes and discovered that the clearance readback by the flight crew had in fact included a 300 degree heading versus the correct 200 degree heading. The crew was given a 'readback correct' by the clearance delivery controller. The supervisor indicated he had acted to correct what was an understandable error and anticipated no further action.

Title: ACR X FLEW WRONG RADAR VECTOR HEADING AFTER TKOF. PLT DEVIATION. CTLR FAILED TO CORRECT INCORRECT CLRNC READBACK. OPERATIONAL DEVIATION.

Narrative: ACR X DEPARTED LAS FROM RWY 01. PASSING APPROX 7000' DEP CTL ASKED IF A TURN HAD BEEN COMMENCED. THE PNF INDICATED THAT THE TURN TO 300 DEGS HAD BEEN COMPLETED. DEP INSTRUCTED AN IMMEDIATE TURN TO 200 DEGS, THEN FURTHER TO 180 DEGS. THE DEP CTLR INDICATED THAT THE HDG SHOULD HAVE BEEN TO 200 DEGS VERSUS 300 DEGS. THE FLT WAS SUBSEQUENTLY TURNED TO A 270 DEG HDG TO INTERCEPT THE ARWY TO BTY. THERE WAS NO INDICATION OF TFC ALERT/CONFLICT OR REQUIREMENT TO REROUTE AIR TFC. SUBSEQUENT DISCUSSIONS WERE CONDUCTED BY PHONE WITH THE LAS TWR RADAR SUPVR. HE INDICATED THAT HE HAD LISTENED TO THE TAPES AND DISCOVERED THAT THE CLRNC READBACK BY THE FLT CREW HAD IN FACT INCLUDED A 300 DEG HDG VERSUS THE CORRECT 200 DEG HDG. THE CREW WAS GIVEN A 'READBACK CORRECT' BY THE CLRNC DELIVERY CTLR. THE SUPVR INDICATED HE HAD ACTED TO CORRECT WHAT WAS AN UNDERSTANDABLE ERROR AND ANTICIPATED NO FURTHER ACTION.
