Narrative:

Cleared into position on runway 11R msp. Runway was wet and during 90 degree turn onto runway the nose wheel 'skipped' a little (normal for an heavy transport). After engines were spooled for takeoff and brakes were released, it was immediately obvious to myself and my crew that the nose wheel was still slightly cocked from the turn onto the runway. As the airplane accelerated, the nose was 'skipping' on the wet concrete. I immediately pulled the throttles closed, deciding the prudent thing to do was to taxi clear and start over (airspeed approximately 20-30 KTS). As the throttles closed and more weight was shifted forward, the aircraft began tracking where the nose wheel was pointing, confirming my suspicions. We taxied clear and got back in line for takeoff. Everything was completely normal during taxi and subsequent takeoff. My company flight operations manual mandates a logbook entry for aborted takeoffs so I wrote a 'comment' writeup indicating what had happened. My supervisors were concerned that since I wrote it up in the logbook (as a comment, not as a mechanic problem) the FAA may feel that we should have taxied back in and have maintenance check the aircraft (for what I don't know). If I had not written up the aborted takeoff, I would be in violation of my company flight operations manual.

Title: ACR HVT LOW SPEED TKOF ABORT DUE COCKED NOSEWHEEL. SUBSEQUENT TKOF NORMAL.

Narrative: CLRED INTO POS ON RWY 11R MSP. RWY WAS WET AND DURING 90 DEG TURN ONTO RWY THE NOSE WHEEL 'SKIPPED' A LITTLE (NORMAL FOR AN HVT). AFTER ENGS WERE SPOOLED FOR TKOF AND BRAKES WERE RELEASED, IT WAS IMMEDIATELY OBVIOUS TO MYSELF AND MY CREW THAT THE NOSE WHEEL WAS STILL SLIGHTLY COCKED FROM THE TURN ONTO THE RWY. AS THE AIRPLANE ACCELERATED, THE NOSE WAS 'SKIPPING' ON THE WET CONCRETE. I IMMEDIATELY PULLED THE THROTTLES CLOSED, DECIDING THE PRUDENT THING TO DO WAS TO TAXI CLR AND START OVER (AIRSPD APPROX 20-30 KTS). AS THE THROTTLES CLOSED AND MORE WT WAS SHIFTED FORWARD, THE ACFT BEGAN TRACKING WHERE THE NOSE WHEEL WAS POINTING, CONFIRMING MY SUSPICIONS. WE TAXIED CLR AND GOT BACK IN LINE FOR TKOF. EVERYTHING WAS COMPLETELY NORMAL DURING TAXI AND SUBSEQUENT TKOF. MY COMPANY FLT OPS MANUAL MANDATES A LOGBOOK ENTRY FOR ABORTED TKOFS SO I WROTE A 'COMMENT' WRITEUP INDICATING WHAT HAD HAPPENED. MY SUPVRS WERE CONCERNED THAT SINCE I WROTE IT UP IN THE LOGBOOK (AS A COMMENT, NOT AS A MECH PROB) THE FAA MAY FEEL THAT WE SHOULD HAVE TAXIED BACK IN AND HAVE MAINT CHK THE ACFT (FOR WHAT I DON'T KNOW). IF I HAD NOT WRITTEN UP THE ABORTED TKOF, I WOULD BE IN VIOLATION OF MY COMPANY FLT OPS MANUAL.
