Flight Crew Air Transport Pilot (ATP)
Deviation - Speed All Types; Inflight Event / Encounter Wake Vortex Encounter
Flight Crew Took Evasive Action
Environment - Non Weather Related; Procedure
On takeoff from 26L behind an Airbus A319; at about 50-100 FT and V2+15; we encountered a wake turbulence event.  We were cleared to takeoff as the previous aircraft was just about rotating. The takeoff was normal; with normal pitch rate and speed. The aircraft buffeted; rolled left and right about 10 to 15 degrees; and stick shaker activated for about 1 second.  The CA was PF and countered the rolling motion with the flight controls; lowered the nose and increased thrust to decrease the AOA.  The event lasted only a few seconds and we returned to the normal takeoff profile.Undesired aircraft state was the stick shaker at an altitude of about 50-100 FT; a rolling motion; and buffet.   This is the third time I have experienced this same exact event behind an A319/320.  I do not recall if I filed an ASAP or not.  In all three cases; the sequence and type of events were identical.  It seems that the A319/320 creates an unusual and/or significant wake turbulence.  I believe the FAA needs to review the wake created by the A319/320.  I also believe that the FAA should review the separation criteria for aircraft departing behind it.  I view this as a significant safety issue and it should be reviewed by both the company and the FAA.
