TKOF ABORTED BECAUSE FLAPS NOT DOWN.

Narrative

WE WERE IN A B-767-300. WE WERE CLRED FOR TKOF AT PDX. AS SOON AS I PUSHED THE PWR UP; WE GOT A CONFIGN WARNING INDICATING THAT OUR FLAPS WERE NOT AT THE CORRECT SETTING FOR TKOF. TKOF WAS DISCONTINUED AT AROUND 30 KTS AND WE NOTICED THE FLAPS AND THE FLAP HANDLE WERE IN THE UP POS. WE TURNED OFF THE RWY; SET THE FLAPS AND MADE A NORMAL TKOF. BOTH OF US COULD NOT BELIEVE THAT WE HAD FORGOTTEN THE FLAPS; A FIRST FOR BOTH; WITH OVER 53 COMBINED YRS OF AIRLINE FLYING. I'LL TRY TO PROVIDE SOME OF THE CIRCUMSTANCES THAT LED TO THIS SIT. I WAS SERVING AS A LINE CHK AIRMAN GIVING INITIAL OPERATING EXPERIENCE TO A CAPT NEW TO THE AIRPLANE. I HAD ONLY FLOWN 3 DAYS IN THE LAST 2 MONTHS AND HAD NOT FLOWN FROM THE R SEAT IN OVER 3 MONTHS. THIS WAS ONE OF OUR NEWER AIRPLANES WITH BIGGER ENGS AND I TOLD HIM THAT WE WOULD HAVE ENOUGH THRUST TO DO A SINGLE ENG TAXI. AS WE STARTED TAXIING; THE CAPT SAW THAT THE TAXI WOULD BE SHORT AND ASKED ME TO START THE SECOND ENG. THIS IS THE TIME I WOULD NORMALLY EXTEND THE FLAPS. AS WE WERE APCHING #1 FOR TKOF; I WAS WAITING FOR THE PAX VIDEO TO FINISH BEFORE I MADE MY BEFORE TKOF PA. WHILE WE WERE WAITING FOR THE FLT ATTENDANT TO REPLY; TWR ASKED US IF WE WERE READY FOR AN IMMEDIATE. I TOLD TWR TO STANDBY AND STARTED READING THE BEFORE TKOF CHKLIST WHILE I WAS REALLY CONCENTRATING ON GETTING A REPLY FROM THE FLT ATTENDANT. I FELT PUSHED AND ALLOWED THIS TO DISTRACT ME ENOUGH TO SOMEHOW MISS THE FLAPS. I RECALL READING THE ITEM; POINTING TO THE FLAPS AND GETTING AN ACKNOWLEDGMENT FROM THE CAPT. I FIND IT AMAZING THAT WE BOTH SAW WHAT WE WANTED TO SEE AND GRATEFUL THE BACKUP SYS WORKED. I CERTAINLY LEARNED A STRONG LESSON AND WON'T LET MYSELF GET RUSHED AND DISTRACTED LIKE THAT AGAIN.
