Narrative:

I was flying air carrier flight from lga to msp on jul/xx/94. I was radar vectored to a 10 mi visual approach to runway 11R. There was a left to right crosswind, 070 degrees at 11 KTS. As I turned final there was a dc-9 abeam us on final approach for runway 11L. The dc-9 overshot the centerline due to the xwinds at altitude. I turned and made an angling final until I was sure the dc- 9 was not a conflict. Between 4000 ft and 3000 ft MSL, I was lined up on the centerline of runway 11R with a slight left bank to maintain runway centerline. At 1000 ft AGL we were configured and on speed with the landing checklist completed. I was using a slight left bank and right rudder to maintain a wings level final approach due to the xwinds, which at altitude were stronger than 070 degrees at 11 KTS. At approximately 3-5 ft AGL the aircraft attitude changed slightly as if it was a hot day with a strong headwind (ground effect). The aircraft then started a slight left to right drift. The aircraft moved just a few ft from the runway centerline. The left wing then dropped abruptly. The left tire touched, I held the nose up and applied right aileron. The aircraft then rolled to the right into a normal rollout attitude. After retracting the flaps the left outboard slat would not retract, which we believed was due to contacting the runway. I believe the cause of the aircraft rolling was wake turbulence from a landing or departing aircraft on runway 11L. The occurrence was at an altitude that did not allow for a go around nor any flight control changes to keep the aircraft from rolling. Supplemental information from acn 275954: in the flare the aircraft picked up a left to right drift. First officer tried to compensate with rudder and aileron. It appeared that the wind gust that caught us to begin with died down. With the control inputs in place, the left wing dropped, striking the runway.

Title: LGT HAS WINGTIP SCRAPE RWY DURING XWIND LNDG.

Narrative: I WAS FLYING ACR FLT FROM LGA TO MSP ON JUL/XX/94. I WAS RADAR VECTORED TO A 10 MI VISUAL APCH TO RWY 11R. THERE WAS A L TO R XWIND, 070 DEGS AT 11 KTS. AS I TURNED FINAL THERE WAS A DC-9 ABEAM US ON FINAL APCH FOR RWY 11L. THE DC-9 OVERSHOT THE CTRLINE DUE TO THE XWINDS AT ALT. I TURNED AND MADE AN ANGLING FINAL UNTIL I WAS SURE THE DC- 9 WAS NOT A CONFLICT. BTWN 4000 FT AND 3000 FT MSL, I WAS LINED UP ON THE CTRLINE OF RWY 11R WITH A SLIGHT L BANK TO MAINTAIN RWY CTRLINE. AT 1000 FT AGL WE WERE CONFIGURED AND ON SPD WITH THE LNDG CHKLIST COMPLETED. I WAS USING A SLIGHT L BANK AND R RUDDER TO MAINTAIN A WINGS LEVEL FINAL APCH DUE TO THE XWINDS, WHICH AT ALT WERE STRONGER THAN 070 DEGS AT 11 KTS. AT APPROX 3-5 FT AGL THE ACFT ATTITUDE CHANGED SLIGHTLY AS IF IT WAS A HOT DAY WITH A STRONG HEADWIND (GND EFFECT). THE ACFT THEN STARTED A SLIGHT L TO R DRIFT. THE ACFT MOVED JUST A FEW FT FROM THE RWY CTRLINE. THE L WING THEN DROPPED ABRUPTLY. THE L TIRE TOUCHED, I HELD THE NOSE UP AND APPLIED R AILERON. THE ACFT THEN ROLLED TO THE R INTO A NORMAL ROLLOUT ATTITUDE. AFTER RETRACTING THE FLAPS THE L OUTBOARD SLAT WOULD NOT RETRACT, WHICH WE BELIEVED WAS DUE TO CONTACTING THE RWY. I BELIEVE THE CAUSE OF THE ACFT ROLLING WAS WAKE TURB FROM A LNDG OR DEPARTING ACFT ON RWY 11L. THE OCCURRENCE WAS AT AN ALT THAT DID NOT ALLOW FOR A GAR NOR ANY FLT CTL CHANGES TO KEEP THE ACFT FROM ROLLING. SUPPLEMENTAL INFO FROM ACN 275954: IN THE FLARE THE ACFT PICKED UP A L TO R DRIFT. FO TRIED TO COMPENSATE WITH RUDDER AND AILERON. IT APPEARED THAT THE WIND GUST THAT CAUGHT US TO BEGIN WITH DIED DOWN. WITH THE CTL INPUTS IN PLACE, THE L WING DROPPED, STRIKING THE RWY.
