Narrative:
We (a DO328) were #2 for takeoff, runway 28L, intersection P at pit, behind an A320. As soon as the A320 started rolling, pit tower cleared us for takeoff (not position and hold). As we entered the runway from taxiway P, my captain commented on how quickly the A320 had rotated, approximately 1/2 way down the runway. As we lined up on the runway centerline, we discussed rotating prior to the A320's point of rotation in order to avoid his wake. We were heavy that day, our V4 speed was 123 KTS. Once we achieved a positive rate and retracted the gear, we flew into the A320's wake at approximately 125 ft AGL. The wake caused an abrupt left wing down and turbulent situation. I immediately corrected, and began a left turn from the runway to further avoid being behind the A320's flight path. Lessons learned: we did a good job of noting where the airbus rotated, and making a plan to avoid its wake. What we should have done was to wait prior to taking off. At the point at which this incident occurred, we had worked 2, 12 1/2 hour duty days, and were at 10 hours 20 mins on oct/wed/00, and had flown 20.7 hours so far, in 3 days of 4 on our trip.

Title: WAKE TURB ENCOUNTER AT PIT, PA.
Narrative: WE (A DO328) WERE #2 FOR TKOF, RWY 28L, INTXN P AT PIT, BEHIND AN A320. AS SOON AS THE A320 STARTED ROLLING, PIT TWR CLRED US FOR TKOF (NOT POS AND HOLD). AS WE ENTERED THE RWY FROM TXWY P, MY CAPT COMMENTED ON HOW QUICKLY THE A320 HAD ROTATED, APPROX 1/2 WAY DOWN THE RWY. AS WE LINED UP ON THE RWY CTRLINE, WE DISCUSSED ROTATING PRIOR TO THE A320'S POINT OF ROTATION IN ORDER TO AVOID HIS WAKE. WE WERE HVY THAT DAY, OUR V4 SPD WAS 123 KTS. ONCE WE ACHIEVED A POSITIVE RATE AND RETRACTED THE GEAR, WE FLEW INTO THE A320'S WAKE AT APPROX 125 FT AGL. THE WAKE CAUSED AN ABRUPT L WING DOWN AND TURBULENT SIT. I IMMEDIATELY CORRECTED, AND BEGAN A L TURN FROM THE RWY TO FURTHER AVOID BEING BEHIND THE A320'S FLT PATH. LESSONS LEARNED: WE DID A GOOD JOB OF NOTING WHERE THE AIRBUS ROTATED, AND MAKING A PLAN TO AVOID ITS WAKE. WHAT WE SHOULD HAVE DONE WAS TO WAIT PRIOR TO TAKING OFF. AT THE POINT AT WHICH THIS INCIDENT OCCURRED, WE HAD WORKED 2, 12 1/2 HR DUTY DAYS, AND WERE AT 10 HRS 20 MINS ON OCT/WED/00, AND HAD FLOWN 20.7 HRS SO FAR, IN 3 DAYS OF 4 ON OUR TRIP.
