Narrative:

After landing on runway 28R I exited the runway at taxiway A6, a high speed taxiway. To get to our facility I had to make left turn on taxiway a (the parallel) to proceed eastbound which is approximately 135 degree turn. I have used this taxi route at least 10 times in the last 12 months. I proceeded to the ramp with everything appearing normal. The tower (ground control) had no comment. I used an exaggerated overshoot of the taxiway a centerline because of the 135 degree turn and that there is no fillet between txwys A6 and a. The next day the pdx port authority/authorized informed our ramp manager that I had damaged 2 taxiway lights with the left main landing gear and a sign with jet blast. In trying to reconstruct the incident in my mind the only thing I can think I did differently than in the past was possibly not proceeding down taxiway A6 far enough before beginning the left turn. Possibly I had become complacent because I have used this route so often in the past. In the future I will use the next taxiway which only requires a 90 degree turn. I know my overshoot of the taxiway a centerline was more than adequate. As far as the minor jet blast damage to the sign, I did not exceed aircraft flight manual authority/authorized taxi power. I was told that other aircraft have damaged this same sign in the recent past, possibly it could be repositioned to take it out of the path of the jet blast.

Title: AFTER EXITING RWY AT TXWY A6, RPTR HAD TO MAKE A 135 DEG L TURN TO ENTER TXWY A. BEING IN A LARGE, HVY ACFT, RPTR TURNED TOO SHARPLY AND HIT TXWY LIGHTS. ARPT PORT AUTH DISCOVERED DAMAGE TO BOTH THE TXWY LIGHTS AND A SIGN FROM JET BLAST.

Narrative: AFTER LNDG ON RWY 28R I EXITED THE RWY AT TXWY A6, A HIGH SPD TXWY. TO GET TO OUR FACILITY I HAD TO MAKE L TURN ON TXWY A (THE PARALLEL) TO PROCEED EBOUND WHICH IS APPROX 135 DEG TURN. I HAVE USED THIS TAXI RTE AT LEAST 10 TIMES IN THE LAST 12 MONTHS. I PROCEEDED TO THE RAMP WITH EVERYTHING APPEARING NORMAL. THE TWR (GND CTL) HAD NO COMMENT. I USED AN EXAGGERATED OVERSHOOT OF THE TXWY A CTRLINE BECAUSE OF THE 135 DEG TURN AND THAT THERE IS NO FILLET BTWN TXWYS A6 AND A. THE NEXT DAY THE PDX PORT AUTH INFORMED OUR RAMP MGR THAT I HAD DAMAGED 2 TXWY LIGHTS WITH THE L MAIN LNDG GEAR AND A SIGN WITH JET BLAST. IN TRYING TO RECONSTRUCT THE INCIDENT IN MY MIND THE ONLY THING I CAN THINK I DID DIFFERENTLY THAN IN THE PAST WAS POSSIBLY NOT PROCEEDING DOWN TXWY A6 FAR ENOUGH BEFORE BEGINNING THE L TURN. POSSIBLY I HAD BECOME COMPLACENT BECAUSE I HAVE USED THIS RTE SO OFTEN IN THE PAST. IN THE FUTURE I WILL USE THE NEXT TXWY WHICH ONLY REQUIRES A 90 DEG TURN. I KNOW MY OVERSHOOT OF THE TXWY A CTRLINE WAS MORE THAN ADEQUATE. AS FAR AS THE MINOR JET BLAST DAMAGE TO THE SIGN, I DID NOT EXCEED ACFT FLT MANUAL AUTH TAXI PWR. I WAS TOLD THAT OTHER ACFT HAVE DAMAGED THIS SAME SIGN IN THE RECENT PAST, POSSIBLY IT COULD BE REPOSITIONED TO TAKE IT OUT OF THE PATH OF THE JET BLAST.

After exiting runway at taxiway A6, reporter had to make a 135 degree left turn to enter taxiway a. Being in a large, heavy aircraft, reporter turned too sharply and hit taxiway lights. Airport port authority/authorized discovered damage to both the taxiway lights and a sign from jet blast.
