Narrative:

Visual approach to runway 1. Winds were reported at 330 degrees at 26 KTS gusting to 41 KTS with moderate turbulence and +/-15 KT windshear below 400 ft AGL. The computed approach speed was vref +25 KTS. We were fully configured and stabilized by the OM with an average descent rate of approximately 600 FPM. Everything was normal until 500 ft AGL when we encountered the turbulence and windshear reported by other aircraft. The ivsi started to fluctuate between 400-1000 FPM descent with momentary spikes of less than a second of 1200-1400 FPM. GS deviations were minor, so I attributed the ivsi excursions to the windshear. I started to flare the aircraft at approximately 3-40 ft. My descent rate did not appear to lessen appreciably. By 20 ft AGL, as the captain yelled 'flare, flare, flare!,' I had full aft stick input. Hard landing inspection was accomplished by maintenance and the aircraft was returned to service that afternoon.

Original NASA ASRS Text

Title: A319 CREW HAD A HARD LNDG AT DCA.

Narrative: VISUAL APCH TO RWY 1. WINDS WERE RPTED AT 330 DEGS AT 26 KTS GUSTING TO 41 KTS WITH MODERATE TURB AND +/-15 KT WINDSHEAR BELOW 400 FT AGL. THE COMPUTED APCH SPD WAS VREF +25 KTS. WE WERE FULLY CONFIGURED AND STABILIZED BY THE OM WITH AN AVERAGE DSCNT RATE OF APPROX 600 FPM. EVERYTHING WAS NORMAL UNTIL 500 FT AGL WHEN WE ENCOUNTERED THE TURB AND WINDSHEAR RPTED BY OTHER ACFT. THE IVSI STARTED TO FLUCTUATE BTWN 400-1000 FPM DSCNT WITH MOMENTARY SPIKES OF LESS THAN A SECOND OF 1200-1400 FPM. GS DEVS WERE MINOR, SO I ATTRIBUTED THE IVSI EXCURSIONS TO THE WINDSHEAR. I STARTED TO FLARE THE ACFT AT APPROX 3-40 FT. MY DSCNT RATE DID NOT APPEAR TO LESSEN APPRECIABLY. BY 20 FT AGL, AS THE CAPT YELLED 'FLARE, FLARE, FLARE!,' I HAD FULL AFT STICK INPUT. HARD LNDG INSPECTION WAS ACCOMPLISHED BY MAINT AND THE ACFT WAS RETURNED TO SVC THAT AFTERNOON.
