Narrative:

I was returning to cma from a level flight, entering the traffic pattern on a right downwind for a touch and go, my traffic was a centurion on a left downwind. As I rolled out on an extended final, I felt a 'wash' from time to time so I offset my approach. Everything appeared normal, the centurion did a touch and go and I extended 30 degrees flaps to land and began reducing to a final approach speed of 65 to 70 KIAS. I crossed the numbers at 50 ft and started a flare to land at 10 ft or so, maybe a little less. I was at 62-65 KIAS, at what I think to be 2 to 3 ft when I hit a vortices from the preceding plane. The nosewheel struck the ground first, I added power and went around and landed without further mishap. I could tell the nosewheel was flat as I kept the weight off of it and taxied back to the line. There was a nick in one of the blades on my post flight. I had about a 6 KT left crosswind but no other indications during the final landing segment (50 ft to the ground) that I would encounter vortices until it happened.

Original NASA ASRS Text

Title: ACFT ENCOUNTERED WAKE TURB JUST PRIOR TO TOUCHDOWN, HIT NOSEWHEEL FIRST AND IT WENT FLAT. GAR EXECUTED AND UNEVENTFUL LNDG FOLLOWED.

Narrative: I WAS RETURNING TO CMA FROM A LEVEL FLT, ENTERING THE TFC PATTERN ON A R DOWNWIND FOR A TOUCH AND GO, MY TFC WAS A CENTURION ON A L DOWNWIND. AS I ROLLED OUT ON AN EXTENDED FINAL, I FELT A 'WASH' FROM TIME TO TIME SO I OFFSET MY APCH. EVERYTHING APPEARED NORMAL, THE CENTURION DID A TOUCH AND GO AND I EXTENDED 30 DEGS FLAPS TO LAND AND BEGAN REDUCING TO A FINAL APCH SPD OF 65 TO 70 KIAS. I CROSSED THE NUMBERS AT 50 FT AND STARTED A FLARE TO LAND AT 10 FT OR SO, MAYBE A LITTLE LESS. I WAS AT 62-65 KIAS, AT WHAT I THINK TO BE 2 TO 3 FT WHEN I HIT A VORTICES FROM THE PRECEDING PLANE. THE NOSEWHEEL STRUCK THE GND FIRST, I ADDED PWR AND WENT AROUND AND LANDED WITHOUT FURTHER MISHAP. I COULD TELL THE NOSEWHEEL WAS FLAT AS I KEPT THE WT OFF OF IT AND TAXIED BACK TO THE LINE. THERE WAS A NICK IN ONE OF THE BLADES ON MY POST FLT. I HAD ABOUT A 6 KT L XWIND BUT NO OTHER INDICATIONS DURING THE FINAL LNDG SEGMENT (50 FT TO THE GND) THAT I WOULD ENCOUNTER VORTICES UNTIL IT HAPPENED.
