Narrative

WINDSHEAR ON TOUCHDOWN RWY 19R LAS; ROCK AND SAND DAMAGE TO ACFT. WINDSHIELDS BROKE; LEADING EDGES; PITTED; PAINT PITTING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE PIC STATED THAT THE BRAND NEW ACFT WAS ON ITS WAY TO PICK UP THE NEW OWNER AND HAD A PLANNED FUEL STOP AT LAS. WX FORECAST WAS FAVORABLE. THE WIND SEEMED TO COME OUT OF NOWHERE WITH VISIBILITY REDUCED TO 'ZERO;' GOING IMC ON THE GND. RPTR SAID HE HAD NEVER SEEN ANYTHING LIKE IT. 6 CPR ACFT ON THE RAMP HAD TO HAVE THEIR ENGS CLEANED OUT FROM THE DEBRIS THAT HAD BEEN CREATED BY THIS 'THING' THAT MAY HAVE BEEN A DUST DEVIL. THE OUTER PANELS OF THE COCKPIT WINDOWS WERE BROKEN; ENABLING A FERRY TO ICT FOR A 3 DAY REPAIR SCHEDULE FOR ACFT RESTORATION. CALLBACK CONVERSATION WITH THE FO ON ACN 473671 REVEALED THE FOLLOWING INFO: THE FO STATED THAT ON LNDG THE ACFT WAS PUSHED TO THE R OF THE RWY; BUT NOT OFF OF IT. THE WINDSHEAR EFFECT WAS LATER ESTIMATED BY ATC TO BE IN THE RANGE OF 80-100 KTS. THE ONLY CLUE THE FO HAD SEEN WAS SOME DUST BLOWING JUST PRIOR TO THE WINDSHEAR ENCOUNTER AND JUST AS THE ACFT TOUCHED DOWN. FO SAID IT WAS LIKE A 'MICRO BURST.' RPTED WINDS WERE FROM THE E AT 18 KTS WITH GUST TO 24 KTS. THE ENGS OF THE ACFT WERE NOT AFFECTED AS THEY WERE STILL AT IDLE AND IN FORWARD THRUST.
