ATC Human Performance
Landing at cys with wind 10 degrees off runway 26. ATIS reported wind from 250 degrees at 20 KTS gusting to 27 KTS. Tower reported wind from 250 degrees at 16 KTS. There were other small aircraft in pattern. Approach to land went normally, with wind correction as expected for wind 10 degrees off runway until 10-15 ft above the runway. I very suddenly sank straight down and then to the right. My airspeed at the time was 75 mph indicated and power was idle. The airplane hit the runway and spun around to the right on the ground. Ground observers (after the fact) told me that the wind sock spun around at the time of the incident. Other ground observer reported wind was from 160 degrees. I had my hand on the throttle ready to do a go around. Everything happened so quickly that I never had a chance to push the throttle in before the plane was on the ground and facing the wrong way. I believe I was caught in a windshear and lost my lift while I was low and slow in a downdraft. To correct: more wind practice, more go around practice.
Original NASA ASRS Text
Title: A PA28 PLT, LNDG AT CYS, ENCOUNTERED A WINDSHEAR DOWNDRAFT AT 15 FT CAUSING ACFT TO SUDDENLY DROP, REVERSING DIRECTION AS IT CONTACTED THE RWY.
Narrative: LNDG AT CYS WITH WIND 10 DEGS OFF RWY 26. ATIS RPTED WIND FROM 250 DEGS AT 20 KTS GUSTING TO 27 KTS. TWR RPTED WIND FROM 250 DEGS AT 16 KTS. THERE WERE OTHER SMALL ACFT IN PATTERN. APCH TO LAND WENT NORMALLY, WITH WIND CORRECTION AS EXPECTED FOR WIND 10 DEGS OFF RWY UNTIL 10-15 FT ABOVE THE RWY. I VERY SUDDENLY SANK STRAIGHT DOWN AND THEN TO THE R. MY AIRSPD AT THE TIME WAS 75 MPH INDICATED AND PWR WAS IDLE. THE AIRPLANE HIT THE RWY AND SPUN AROUND TO THE R ON THE GND. GND OBSERVERS (AFTER THE FACT) TOLD ME THAT THE WIND SOCK SPUN AROUND AT THE TIME OF THE INCIDENT. OTHER GND OBSERVER RPTED WIND WAS FROM 160 DEGS. I HAD MY HAND ON THE THROTTLE READY TO DO A GAR. EVERYTHING HAPPENED SO QUICKLY THAT I NEVER HAD A CHANCE TO PUSH THE THROTTLE IN BEFORE THE PLANE WAS ON THE GND AND FACING THE WRONG WAY. I BELIEVE I WAS CAUGHT IN A WINDSHEAR AND LOST MY LIFT WHILE I WAS LOW AND SLOW IN A DOWNDRAFT. TO CORRECT: MORE WIND PRACTICE, MORE GAR PRACTICE.
