Narrative:

On landing flare at teb runway 1, encountered windshear and strong crosswind gust from left side of aircraft. Evasive action on my part included rapid full left aileron deflection as aircraft rolled violently to the right. Right gear contacted ground, then left gear, and then nose. PNF applied speed brakes and I applied thrust reversers. We taxied off runway. PNF told tower of windshear. At this point, we did not know the right wing had contacted the ground. After exiting aircraft, ground person showed us damage to right wing including broken navigation lens, scraped tip and slat. PNF immediately contacted tower to inform them of broken navigation lens glass on runway. This aircraft (a CE750 citation X) has an improvement with greater aileron control response on new aircraft. I believe it might also be offered as a modification to our aircraft. In my mind, I am wondering if this modification would have prevented us from striking the wingtip in these conditions. Note: metar after situation 310 degrees at 19 KTS gusting to 25 KTS, 'pk wnd 33030, XA35.

Title: C750 CREW LOST ACFT CTL DURING LNDG IN GUSTY WIND CONDITIONS AT TEB.

Narrative: ON LNDG FLARE AT TEB RWY 1, ENCOUNTERED WINDSHEAR AND STRONG XWIND GUST FROM L SIDE OF ACFT. EVASIVE ACTION ON MY PART INCLUDED RAPID FULL L AILERON DEFLECTION AS ACFT ROLLED VIOLENTLY TO THE R. R GEAR CONTACTED GND, THEN L GEAR, AND THEN NOSE. PNF APPLIED SPD BRAKES AND I APPLIED THRUST REVERSERS. WE TAXIED OFF RWY. PNF TOLD TWR OF WINDSHEAR. AT THIS POINT, WE DID NOT KNOW THE R WING HAD CONTACTED THE GND. AFTER EXITING ACFT, GND PERSON SHOWED US DAMAGE TO R WING INCLUDING BROKEN NAV LENS, SCRAPED TIP AND SLAT. PNF IMMEDIATELY CONTACTED TWR TO INFORM THEM OF BROKEN NAV LENS GLASS ON RWY. THIS ACFT (A CE750 CITATION X) HAS AN IMPROVEMENT WITH GREATER AILERON CTL RESPONSE ON NEW ACFT. I BELIEVE IT MIGHT ALSO BE OFFERED AS A MODIFICATION TO OUR ACFT. IN MY MIND, I AM WONDERING IF THIS MODIFICATION WOULD HAVE PREVENTED US FROM STRIKING THE WINGTIP IN THESE CONDITIONS. NOTE: METAR AFTER SIT 310 DEGS AT 19 KTS GUSTING TO 25 KTS, 'PK WND 33030, XA35.
