Narrative:
During departure at about 1500 ft AGL the automatic thrust bell sounded warning light came on showing automatic thrust failure. Straight ahead climb was continued on runway heading and manual thrust control used to stop engines from going to unwind. Automatic thrust was engaged again at climb thrust. ATC asked if we had turned to 330 degree heading which we hadn't. We then turned to 330 degrees to intercept the 314 degree radial out of mustang VOR but we had crossed it already. ATC asked if we were intercepting and our reply was, not yet. They then cleared us direct to lkv VOR. The change in routing had been copied currently from clearance delivery but was not flown due to more pressing problem of getting climb power back as automatic thrust was kicked off. After climb power was reestablished, we were off the departure profile. This was necessary because no turns should be made until climb power was established.

Title: FLC OF ACR MLG ACFT DEVIATED FROM ASSIGNED SID TRACK BECAUSE OF AN ENG CTL MALFUNCTION.
Narrative: DURING DEP AT ABOUT 1500 FT AGL THE AUTO THRUST BELL SOUNDED WARNING LIGHT CAME ON SHOWING AUTO THRUST FAILURE. STRAIGHT AHEAD CLB WAS CONTINUED ON RWY HDG AND MANUAL THRUST CTL USED TO STOP ENGS FROM GOING TO UNWIND. AUTO THRUST WAS ENGAGED AGAIN AT CLB THRUST. ATC ASKED IF WE HAD TURNED TO 330 DEG HDG WHICH WE HADN'T. WE THEN TURNED TO 330 DEGS TO INTERCEPT THE 314 DEG RADIAL OUT OF MUSTANG VOR BUT WE HAD CROSSED IT ALREADY. ATC ASKED IF WE WERE INTERCEPTING AND OUR REPLY WAS, NOT YET. THEY THEN CLRED US DIRECT TO LKV VOR. THE CHANGE IN ROUTING HAD BEEN COPIED CURRENTLY FROM CLRNC DELIVERY BUT WAS NOT FLOWN DUE TO MORE PRESSING PROBLEM OF GETTING CLB PWR BACK AS AUTO THRUST WAS KICKED OFF. AFTER CLB PWR WAS REESTABLISHED, WE WERE OFF THE DEP PROFILE. THIS WAS NECESSARY BECAUSE NO TURNS SHOULD BE MADE UNTIL CLB PWR WAS ESTABLISHED.
