Narrative:

Cleared for takeoff on runway 17 owb. The captain advanced the power levers roughly overlooking the fact that the #2 engine was still on the start lock and the aircraft yawed approximately 45-50 degrees right of centerline. The captain was hesitant to retard the power levers to flight idle allowing the aircraft to do this. I called out twice that the lock was still engaged. After the power levers were retarded the captain called for speeds low and he realigned the aircraft on centerline, asked if takeoff clearance was still good and then proceeded to release the locks on lock engine. Called for speeds high and advanced the power levers for takeoff thrust and departed the area. I do believe this would not have happened if the captain did not advance the power levers so roughly. If they were advanced smoothly, the torque gauges would have showed that the #2 engine was not producing takeoff power.

Original NASA ASRS Text

Title: LTT VEERS OFF CENTERLINE AS POWER IS APPLIED WITH START LOCK STILL ON 1 ENGINE.

Narrative: CLRED FOR TKOF ON RWY 17 OWB. THE CAPT ADVANCED THE PWR LEVERS ROUGHLY OVERLOOKING THE FACT THAT THE #2 ENG WAS STILL ON THE START LOCK AND THE ACFT YAWED APPROX 45-50 DEGS RIGHT OF CENTERLINE. THE CAPT WAS HESITANT TO RETARD THE PWR LEVERS TO FLT IDLE ALLOWING THE ACFT TO DO THIS. I CALLED OUT TWICE THAT THE LOCK WAS STILL ENGAGED. AFTER THE PWR LEVERS WERE RETARDED THE CAPT CALLED FOR SPDS LOW AND HE REALIGNED THE ACFT ON CENTERLINE, ASKED IF TKOF CLRNC WAS STILL GOOD AND THEN PROCEEDED TO RELEASE THE LOCKS ON LOCK ENG. CALLED FOR SPDS HIGH AND ADVANCED THE PWR LEVERS FOR TKOF THRUST AND DEPARTED THE AREA. I DO BELIEVE THIS WOULD NOT HAVE HAPPENED IF THE CAPT DID NOT ADVANCE THE PWR LEVERS SO ROUGHLY. IF THEY WERE ADVANCED SMOOTHLY, THE TORQUE GAUGES WOULD HAVE SHOWED THAT THE #2 ENG WAS NOT PRODUCING TKOF PWR.
