Narrative:

Forgot to lower flaps until receiving the takeoff warning sounds and lights during takeoff. We repositioned back to the end of the runway and continued. So, what went wrong with something as critical as setting takeoff flaps? A simple break in the routine and insidious complacency. The captain always called for takeoff flaps immediately after blockout. He called for the takeoff briefing on the parallel taxiway followed immediately by the before takeoff checklist. In this case, doing the takeoff briefing in the chocks broke the chain and led to errors of substitution and omission. We normally checked the flaps, speed brakes and trim several times during taxi. But, this one time -- while tired and running late with a short taxi at a familiar airport, a clearance change, and the distraction of a fighter takeoff -- we let our guard down.

Original NASA ASRS Text

Title: A B757 CREW, STARTING THEIR TKOF ROLL AT EFD, RECEIVED AN AURAL 'TKOF' WARNING BECAUSE THE FLAPS WERE STILL UP.

Narrative: FORGOT TO LOWER FLAPS UNTIL RECEIVING THE TKOF WARNING SOUNDS AND LIGHTS DURING TKOF. WE REPOSITIONED BACK TO THE END OF THE RWY AND CONTINUED. SO, WHAT WENT WRONG WITH SOMETHING AS CRITICAL AS SETTING TKOF FLAPS? A SIMPLE BREAK IN THE ROUTINE AND INSIDIOUS COMPLACENCY. THE CAPT ALWAYS CALLED FOR TKOF FLAPS IMMEDIATELY AFTER BLOCKOUT. HE CALLED FOR THE TKOF BRIEFING ON THE PARALLEL TXWY FOLLOWED IMMEDIATELY BY THE BEFORE TKOF CHKLIST. IN THIS CASE, DOING THE TKOF BRIEFING IN THE CHOCKS BROKE THE CHAIN AND LED TO ERRORS OF SUBSTITUTION AND OMISSION. WE NORMALLY CHKED THE FLAPS, SPD BRAKES AND TRIM SEVERAL TIMES DURING TAXI. BUT, THIS ONE TIME -- WHILE TIRED AND RUNNING LATE WITH A SHORT TAXI AT A FAMILIAR ARPT, A CLRNC CHANGE, AND THE DISTR OF A FIGHTER TKOF -- WE LET OUR GUARD DOWN.
