Narrative:

A320 airbus phx to tus. WX in tus -- high ceiling, good visibility except for occasional blowing dust. Wind approximately 220 degrees at 20 KTS gusts to 35 KTS. Clearance was ILS runway 11, circle to land (runway 21) at 1500 ft AGL, tracking the localizer on a heading of 145 degrees. Wind at 1500 ft AGL was 200 degrees at 45 KTS. At 1500 ft we broke off the ILS and turned left for a right downwind to runway 21 (see diagram). The new tailwind component gave aircraft a ground speed in excess of 185 KTS. Tower told us to remain west of highway I-10. Strong tailwind component pushed our path over highway I-10 (east). No TCASII or other problems occurred due to crossing highway I-10. Tower did not request us to call them or suggest a violation. On short final at 200 ft to 40 ft AGL, the wind was gusting 20-35 KTS. At 40 ft per A320 SOP. I retarded the thrust levers to idle. At 20 ft AGL aircraft hit a wind shear, airspeed dropped at least 20 KTS and the A320 did what it was designed to do -- it landed hard. The landing was not hard enough to set off a shock compression fault warning.

Title: A-320 PERFORMS A HARD LNDG.

Narrative: A320 AIRBUS PHX TO TUS. WX IN TUS -- HIGH CEILING, GOOD VISIBILITY EXCEPT FOR OCCASIONAL BLOWING DUST. WIND APPROX 220 DEGS AT 20 KTS GUSTS TO 35 KTS. CLRNC WAS ILS RWY 11, CIRCLE TO LAND (RWY 21) AT 1500 FT AGL, TRACKING THE LOC ON A HDG OF 145 DEGS. WIND AT 1500 FT AGL WAS 200 DEGS AT 45 KTS. AT 1500 FT WE BROKE OFF THE ILS AND TURNED L FOR A R DOWNWIND TO RWY 21 (SEE DIAGRAM). THE NEW TAILWIND COMPONENT GAVE ACFT A GND SPD IN EXCESS OF 185 KTS. TWR TOLD US TO REMAIN W OF HWY I-10. STRONG TAILWIND COMPONENT PUSHED OUR PATH OVER HWY I-10 (E). NO TCASII OR OTHER PROBS OCCURRED DUE TO XING HWY I-10. TWR DID NOT REQUEST US TO CALL THEM OR SUGGEST A VIOLATION. ON SHORT FINAL AT 200 FT TO 40 FT AGL, THE WIND WAS GUSTING 20-35 KTS. AT 40 FT PER A320 SOP. I RETARDED THE THRUST LEVERS TO IDLE. AT 20 FT AGL ACFT HIT A WIND SHEAR, AIRSPD DROPPED AT LEAST 20 KTS AND THE A320 DID WHAT IT WAS DESIGNED TO DO -- IT LANDED HARD. THE LNDG WAS NOT HARD ENOUGH TO SET OFF A SHOCK COMPRESSION FAULT WARNING.
