Narrative:

I am convinced the stem of this problem came from having a reduced rest of 8 hours the previous night after being on duty for 14 hours. The incident happened, I feel, as a direct result of a long day previous, followed by a reduced rest followed the next morning by a 6 1/2 hour break between legs. Even though I did not feel fatigued, I noticed myself making small errors all day -- the worst of which was the runway incursion. Our usual route is to taxi via taxiway a, taxiway north, taxiway P to runway 13R. While taxiing out, we experienced a bleed problem on the #2 engine. While diagnosing the problem, keeping with our normal route, we would make an s-turn to the left to move to taxiway P. Being tired and distraction, I made the left turn onto runway 13R by 30-40 ft. I immediately turned around and rejoined taxiway P. Thankfully, no one was departing or landing on runway 13R at that time. I very strongly feel the duty day, with the reduced rest was a strong contributing factor to this. Although you may feel rested, doesn't mean you are adequately rested!

Title: RWY INCURSION AT JFK, NY.

Narrative: I AM CONVINCED THE STEM OF THIS PROB CAME FROM HAVING A REDUCED REST OF 8 HRS THE PREVIOUS NIGHT AFTER BEING ON DUTY FOR 14 HRS. THE INCIDENT HAPPENED, I FEEL, AS A DIRECT RESULT OF A LONG DAY PREVIOUS, FOLLOWED BY A REDUCED REST FOLLOWED THE NEXT MORNING BY A 6 1/2 HR BREAK BTWN LEGS. EVEN THOUGH I DID NOT FEEL FATIGUED, I NOTICED MYSELF MAKING SMALL ERRORS ALL DAY -- THE WORST OF WHICH WAS THE RWY INCURSION. OUR USUAL RTE IS TO TAXI VIA TXWY A, TXWY N, TXWY P TO RWY 13R. WHILE TAXIING OUT, WE EXPERIENCED A BLEED PROB ON THE #2 ENG. WHILE DIAGNOSING THE PROB, KEEPING WITH OUR NORMAL RTE, WE WOULD MAKE AN S-TURN TO THE L TO MOVE TO TXWY P. BEING TIRED AND DISTR, I MADE THE L TURN ONTO RWY 13R BY 30-40 FT. I IMMEDIATELY TURNED AROUND AND REJOINED TXWY P. THANKFULLY, NO ONE WAS DEPARTING OR LNDG ON RWY 13R AT THAT TIME. I VERY STRONGLY FEEL THE DUTY DAY, WITH THE REDUCED REST WAS A STRONG CONTRIBUTING FACTOR TO THIS. ALTHOUGH YOU MAY FEEL RESTED, DOESN'T MEAN YOU ARE ADEQUATELY RESTED!
