Narrative:

This is a human factors problem. We didn't have the flaps in the takeoff position when we were cleared for takeoff. Flaps are both on the taxi and takeoff checklists. I read the taxi checklist but must have forgotten the flaps, it was the captain's leg to fly. 100-150 meters before the hold short we were cleared for takeoff. Neither of us called for the takeoff checklist. Once crossing the hold short, I began to read the before takeoff checklist. I advised the captain the flaps were up and we had not done a takeoff checklist. I suppose he didn't hear me. As he was adding takeoff power, we got the takeoff warning horn. We taxied off the runway, did the checklist and took off. I was startled I had not done my duty. Even though the book says the captain will call for checklists on the ground, I'm the one holding it in my hand. It's still my responsibility. I was extremely tired from not getting any sleep the night before in nyc. Fire trucks, police cars, etc. I felt a little groggy. Also, I'm trying to determine if my relationships with the captain had anything to do with it. He has 1.5 yrs to retirement and is a nervous nellie, a micro manager, and is always running the FMS and mode control panel on my legs. Normally it doesn't bother me. But he is really short on patience -- almost like flying scared. He is also having physical stress from sinus infections caused by a deviated septum. Normally I watch out for guys like him. I want to help them get to retirement, but with feeling so tired I guess I lost some motivation. The problem is easy to fix: when tired, use more self discipline. Especially on a 2 man crew, tell the other guy what you want him to do. No surprises, no stress. Read the checklist. I wasn't going to let him take off. I told him to abort, we were barely rolling. That time he heard me.

Title: TKOF ABORTED, NO FLAPS.

Narrative: THIS IS A HUMAN FACTORS PROB. WE DIDN'T HAVE THE FLAPS IN THE TKOF POS WHEN WE WERE CLRED FOR TKOF. FLAPS ARE BOTH ON THE TAXI AND TKOF CHKLISTS. I READ THE TAXI CHKLIST BUT MUST HAVE FORGOTTEN THE FLAPS, IT WAS THE CAPT'S LEG TO FLY. 100-150 METERS BEFORE THE HOLD SHORT WE WERE CLRED FOR TKOF. NEITHER OF US CALLED FOR THE TKOF CHKLIST. ONCE XING THE HOLD SHORT, I BEGAN TO READ THE BEFORE TKOF CHKLIST. I ADVISED THE CAPT THE FLAPS WERE UP AND WE HAD NOT DONE A TKOF CHKLIST. I SUPPOSE HE DIDN'T HEAR ME. AS HE WAS ADDING TKOF PWR, WE GOT THE TKOF WARNING HORN. WE TAXIED OFF THE RWY, DID THE CHKLIST AND TOOK OFF. I WAS STARTLED I HAD NOT DONE MY DUTY. EVEN THOUGH THE BOOK SAYS THE CAPT WILL CALL FOR CHKLISTS ON THE GND, I'M THE ONE HOLDING IT IN MY HAND. IT'S STILL MY RESPONSIBILITY. I WAS EXTREMELY TIRED FROM NOT GETTING ANY SLEEP THE NIGHT BEFORE IN NYC. FIRE TRUCKS, POLICE CARS, ETC. I FELT A LITTLE GROGGY. ALSO, I'M TRYING TO DETERMINE IF MY RELATIONSHIPS WITH THE CAPT HAD ANYTHING TO DO WITH IT. HE HAS 1.5 YRS TO RETIREMENT AND IS A NERVOUS NELLIE, A MICRO MGR, AND IS ALWAYS RUNNING THE FMS AND MODE CTL PANEL ON MY LEGS. NORMALLY IT DOESN'T BOTHER ME. BUT HE IS REALLY SHORT ON PATIENCE -- ALMOST LIKE FLYING SCARED. HE IS ALSO HAVING PHYSICAL STRESS FROM SINUS INFECTIONS CAUSED BY A DEVIATED SEPTUM. NORMALLY I WATCH OUT FOR GUYS LIKE HIM. I WANT TO HELP THEM GET TO RETIREMENT, BUT WITH FEELING SO TIRED I GUESS I LOST SOME MOTIVATION. THE PROB IS EASY TO FIX: WHEN TIRED, USE MORE SELF DISCIPLINE. ESPECIALLY ON A 2 MAN CREW, TELL THE OTHER GUY WHAT YOU WANT HIM TO DO. NO SURPRISES, NO STRESS. READ THE CHKLIST. I WASN'T GOING TO LET HIM TAKE OFF. I TOLD HIM TO ABORT, WE WERE BARELY ROLLING. THAT TIME HE HEARD ME.
