## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

LOST DIRECTIONAL CONTROL ON 3 POINT LANDING. SKIDDED OFF RWY. BENT LEFT WING AND FOLDED LEFT MAIN GEAR. (.4)THE PILOT WAS GIVEN AIRPORT ADVISORIES ON UNICOM.  HE WAS TOLD THAT THE ACTIVE RUNWAY WAS 29 AND THAT THE WIND WAS 'LIGHT AND VARIABLE.'  HE SAID THAT THE 'WINDSOCK'S MOVEMENT WAS HARDLY PERCEPTIBLE AND THE VELOCITY OF THE INDICATOR INDICATED LESS THAN 5 KNOTS.'  THE PILOT REPORTED THAT AFTER TOUCHDOWN, 'THE AIRCRAFT'S ROLLOUT PATH TOOK MULTIPLE, SHORT, QUICK INPUTS FROM THE RUDDER TO KEEP PROPERLY ALIGNED WITH THE RUNWAY CENTERLINE AS THE AIRCRAFT PROCEEDED DOWN THE RUNWAY.'  HE FURTHER REPORTED THE RUDDER INPUTS BECAME INEFFECTIVE AFTER APPROXIMATELY 400 TO 500 FEET OF LANDING ROLL AND THE AIRCRAFT EXITED THE RIGHT SIDE OF THE RUNWAY. THE AIRCRAFT SUBSEQUENTLY IMPACTED AN AIRPORT TAXIWAY SIGN, DAMAGING THE LEFT MAIN LANDING GEAR AND THE LEFT WING.  THE AIRCRAFT CAME TO REST WITH ITS NOSE DOWN.  THE PILOT SAID THAT THE TAIL WHEEL STEERING CABLES HAD RECENTLY BEEN REPLACED.  POSTACCIDENT EVALUATION OF THE TAIL WHEEL STEERING CABLES BY MAINTENANCE PERSONNEL FOUND A TENSION OF 5 POUNDS ON THESE CABLES; 20 POUNDS IS CONSIDERED NORMAL                                              (-23)EVERYTHING SEEMED NORMAL WITH THE APPROACH TO RUNWAY 29 AT 2V2. PILOT STATED HE DECIDED A THREE-POINT LANDING WAS APPROPRIATE.  WHEN THE AIRCRAFT TOUCHED DOWN, IT IMMEDIATELY WENT INOT A SKID TO THE LEFT, DEPARTED THE RUNWAY AND ACROSS A TAXIWAY ONTO A GRASSY AREA WHERE IT CAME TO REST.  THE WING WAS BENT WHEN THE LEFT GEAR COLLAPSED.
