Narrative:

When cleared for a visual approach to runway 29L; a BE35 was cleared to land runway 29R. The BE35 overtook me and landed before I did; somewhere along runway 29R. As I touched down; pretty close to the runway 29L numbers; I encountered what I believe to be wake turbulence. This caused me to yaw violently to the left with severe fishtailing back and forth across the centerline. Directional control was marginal to non existent for a few seconds. I was not warned about wake turbulence danger but that is no excuse. I had never thought wake turbulence could be a problem from a parallel runway. I should have landed beyond the touchdown of the BE35 or declared a 'go around.' further; I now see on the airport diagram there is a warning about possible wake turbulence; when arriving runway 29L; caused by testing on the ramp at the southeast corner of the airport. I have now learned never to relax; even though the mains and nose have touched down; until the aircraft is well decelerated to a safe and smooth braking speed. There was about a 3-4 KT tailwind at this time.

Original NASA ASRS Text

Title: THE PLT OF A C182 ENCOUNTERED WHAT HE BELIEVED TO BE WAKE TURB AFTER TOUCHDOWN AT FAT. THE ENCOUNTER CAUSED SEVERE DIRECTIONAL CTL DIFFICULTIES.

Narrative: WHEN CLRED FOR A VISUAL APCH TO RWY 29L; A BE35 WAS CLRED TO LAND RWY 29R. THE BE35 OVERTOOK ME AND LANDED BEFORE I DID; SOMEWHERE ALONG RWY 29R. AS I TOUCHED DOWN; PRETTY CLOSE TO THE RWY 29L NUMBERS; I ENCOUNTERED WHAT I BELIEVE TO BE WAKE TURB. THIS CAUSED ME TO YAW VIOLENTLY TO THE L WITH SEVERE FISHTAILING BACK AND FORTH ACROSS THE CTRLINE. DIRECTIONAL CTL WAS MARGINAL TO NON EXISTENT FOR A FEW SECONDS. I WAS NOT WARNED ABOUT WAKE TURB DANGER BUT THAT IS NO EXCUSE. I HAD NEVER THOUGHT WAKE TURB COULD BE A PROB FROM A PARALLEL RWY. I SHOULD HAVE LANDED BEYOND THE TOUCHDOWN OF THE BE35 OR DECLARED A 'GAR.' FURTHER; I NOW SEE ON THE ARPT DIAGRAM THERE IS A WARNING ABOUT POSSIBLE WAKE TURB; WHEN ARRIVING RWY 29L; CAUSED BY TESTING ON THE RAMP AT THE SE CORNER OF THE ARPT. I HAVE NOW LEARNED NEVER TO RELAX; EVEN THOUGH THE MAINS AND NOSE HAVE TOUCHED DOWN; UNTIL THE ACFT IS WELL DECELERATED TO A SAFE AND SMOOTH BRAKING SPD. THERE WAS ABOUT A 3-4 KT TAILWIND AT THIS TIME.
