PIPER PA22 PVT PLT LOST DIRECTIONAL CTL IN A XWIND DURING TKOF CAUSING HIM TO DRIFT OVER THE ARPT RAMP AND HANGARS ON CLBOUT. AFTER CLRING THE HANGARS; THE RPTR REGAINED DIRECTIONAL CTL.

Narrative

WHILE DEPARTING RWY 29 AT LONGMONT; CO; I EXPERIENCED LOSS OF DIRECTIONAL AUTH DUE TO WIND ON TKOF RESULTING IN MY AIRPLANE FLYING OVER THE ARPT RAMP AND NEAR HANGARS ON CLBOUT. THE WIND WAS BLOWING FROM L TO R AND APPEARED MANAGEABLE. A STORM WAS DEVELOPING S OF THE ARPT AND RPTED TO BE MOVING NE. TAXI OUT WAS NORMAL. TKOF ROLL WAS AS EXPECTED. ROTATED TO CLB; RESULTED IN THE WIND BLOWING THE AIRPLANE TO THE R AND AILERON DEFLECTION TO THE L DID NOT CORRECT THE SIT. FEARFUL OF FLYING LOW OVER THE RAMP; I PULLED THE NOSE UP TO INCREASE CLB WHILE MAINTAINING L BANK INTO THE WIND; PRAYING TO GET BACK TO RWY CTR. THE WIND CONTINUED TO PUSH THE AIRPLANE TO THE R TOWARDS HANGARS. ONCE CLR OF THESE HANGARS AND A SAFE CLB ESTABLISHED; I TURNED TO COURSE. CONTINUATION OF THE FLT TO MY DEST WAS WITHOUT FURTHER INCIDENT ENDING IN A NORMAL XWIND LNDG. THIS EVENT WAS SO FRIGHTFUL AND MY CONFIDENCE SO INSULTED THAT I HAD TO REMIND MYSELF TO CALM DOWN AND FLY THE AIRPLANE. WHEN HOME; I CALLED MY FLT INSTRUCTOR AND DESCRIBED THE EVENT TO HIM AND REQUESTED SOME DUAL TIME TO DISCOVER IF MY TECHNIQUE FOR XWIND TKOF WAS BAD OR MAYBE I HAD DEVELOPED BAD TKOF HABITS. HE AGREED AND ON JUN/MON/01 AT XA30 WE FLEW 1 HR OF DUAL; MADE SEVERAL XWIND TKOFS AND LNDGS WITHOUT ANY PROBS. THE FLT INSTRUCTOR LOANED ME A KING VIDEO ON TKOF AND LNDGS IN XWIND; AND WE PLAN TO FLY DUAL AGAIN TO MAKE SURE MY SKILLS ARE AS SHOULD BE. I WILL NEVER AGAIN TAKE OFF IN WHAT LOOKS LIKE A MANAGEABLE XWIND WHEN IT IS BLOWING TOWARDS PEOPLE OR STRUCTURES IN LIGHT ACFT. I NOW KNOW WINDS MAY BE STRONGER THAN THEY APPEAR A FEW FT ABOVE THE SURFACE AND ESPECIALLY WHEN A DISTANT STORM MAY BE DEVELOPING.
