Narrative:
Momentary loss of directional control during the end of the landing ground roll. Wheel landing technique was used on runway 24 at crq. During the approach and ground roll I observed the wind sock limp but indicating a 90 degree right crosswind. As the aircraft decelerated I held the tail up with full forward stick. I remember thinking that the tail should be coming down by now because of the low speed attained. I then went through 4 yaw oscillations with the initial disturbance being the tail moving left. On the third oscillation I lost directional control ending up off runway 24 on the r-hand side. I did not have full aileron deflection in to the wind during the landing ground roll. The limp wind sock lulled me into a false sense of security. The instant the yawing oscillations began I failed to apply full aft stick. This would have loaded the tailwheel and provided tailwheel steering. As the aircraft crossed over the edge of the runway onto the dirt I simultaneously applied full throttle and full right aft stick. Directional control was immediately regained. The aircraft accelerated parallel to the runway and after a short ground roll was airborne. I teach the need to apply crosswind corrections regardless of the wind velocity, why I did not apply what I teach in this instance? As stated above, I fixated on the use of the rudder to correct the directional control problem. I had at my disposal, but did not use, ailerons -- full into the wind, elevator -- load the tail, tailwheel steering, and differential brake application. Problem: fixation and the resulting omission of other options.

Title: THE PLT OF A CONVENTIONAL GEAR ACFT EXPERIENCED XWIND RELATED ACFT CTL PROBS, AND EXITED THE RWY. CTL WAS REGAINED WITH THE EXECUTION OF A GAR.
Narrative: MOMENTARY LOSS OF DIRECTIONAL CTL DURING THE END OF THE LNDG GND ROLL. WHEEL LNDG TECHNIQUE WAS USED ON RWY 24 AT CRQ. DURING THE APCH AND GND ROLL I OBSERVED THE WIND SOCK LIMP BUT INDICATING A 90 DEG R XWIND. AS THE ACFT DECELERATED I HELD THE TAIL UP WITH FULL FORWARD STICK. I REMEMBER THINKING THAT THE TAIL SHOULD BE COMING DOWN BY NOW BECAUSE OF THE LOW SPD ATTAINED. I THEN WENT THROUGH 4 YAW OSCILLATIONS WITH THE INITIAL DISTURBANCE BEING THE TAIL MOVING L. ON THE THIRD OSCILLATION I LOST DIRECTIONAL CTL ENDING UP OFF RWY 24 ON THE R-HAND SIDE. I DID NOT HAVE FULL AILERON DEFLECTION IN TO THE WIND DURING THE LNDG GND ROLL. THE LIMP WIND SOCK LULLED ME INTO A FALSE SENSE OF SECURITY. THE INSTANT THE YAWING OSCILLATIONS BEGAN I FAILED TO APPLY FULL AFT STICK. THIS WOULD HAVE LOADED THE TAILWHEEL AND PROVIDED TAILWHEEL STEERING. AS THE ACFT CROSSED OVER THE EDGE OF THE RWY ONTO THE DIRT I SIMULTANEOUSLY APPLIED FULL THROTTLE AND FULL R AFT STICK. DIRECTIONAL CTL WAS IMMEDIATELY REGAINED. THE ACFT ACCELERATED PARALLEL TO THE RWY AND AFTER A SHORT GND ROLL WAS AIRBORNE. I TEACH THE NEED TO APPLY XWIND CORRECTIONS REGARDLESS OF THE WIND VELOCITY, WHY I DID NOT APPLY WHAT I TEACH IN THIS INSTANCE? AS STATED ABOVE, I FIXATED ON THE USE OF THE RUDDER TO CORRECT THE DIRECTIONAL CTL PROB. I HAD AT MY DISPOSAL, BUT DID NOT USE, AILERONS -- FULL INTO THE WIND, ELEVATOR -- LOAD THE TAIL, TAILWHEEL STEERING, AND DIFFERENTIAL BRAKE APPLICATION. PROB: FIXATION AND THE RESULTING OMISSION OF OTHER OPTIONS.
