ACFT ENCOUNTERED WINDSHEAR JUST AS THE FLARE MANEUVER WAS BEGUN. RIGHT WING TIP STRUCK THE GND CAUSING MINOR DAMAGE.

Narrative

THE F/O WAS LNDG ON RWY 27L AT ATL. ON 5 MI FINAL I NOTED AIRSPD INDICATOR FLUCTUATIONS WHICH CAUSED ME TO BE SUSPICIOUS OF THE WIND THAT TWR HAD JUST RPTED TO US OF 330/13. I ADJUSTED APCH SPD UP TO 137 KTS WHICH PROVIDED FOR A NORMAL STABILIZED APCH. AT 10' RA STRONG GUST WAS EXPERIENCED WHICH CAUSED A VERY ABRUPT LEFT ROLL. RIGHT AILERON WAS IMMEDIATELY APPLIED TO BRING WINGS LEVEL. T/D AND ROLLOUT WERE NORMAL. ON TAXI IN ATC COMMENTED; 'WE NOTICED YOUR WING LOW; DID YOU HAVE A PROB? WE DIDN'T NOTICE ANYTHING.' SINCE WE FELT NOTHING FROM THE COCKPIT WE SAID 'NO.' AFTER COMPLETION OF PARKING CHKLIST I INSPECTED LEFT WING TO FIND SLIGHT WING TIP DAMAGE. UPON REFLECTION; I FEEL THAT DUE TO THE DISPLACEMENT OF RWY 27R AND PREVAILING WIND CONDITIONS; WE MAY HAVE ENCOUNTERED WAKE TURB FROM ACFT TAKING OFF ON RWY 27R. DAMAGE WAS NOTED IN E-6 LOG AND COMPANY NOTIFIED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: ACTUAL WIND AT TIME OF T/D WAS 330/26. A COMPANY HEARING WAS HELD AND MGMNT BROUGHT OUT THE POSSIBILITY OF WIND SHEAR AND THE EFFECT OF THE DEPARTING ACFT ON THE PARALLEL RWY. REMEDIAL TRNING WAS PROGRAMMED AND THE FLT CREW PASSED WITH FLYING COLORS. DAMAGE TO THE WING TIP WAS VERY MINOR AND THE ACFT WAS BACK IN SERVICE THAT EVENING. CAPT WAS NOT QUESTIONED AS TO LETTING THE FAIRLY NEW F/O MAKE THE APCH AND LNDG.
