While departing runway 29 at longmont, co, I experienced loss of directional authority/authorized due to wind on takeoff resulting in my airplane flying over the airport ramp and near hangars on climb out. The wind was blowing from left to right and appeared manageable. A storm was developing south of the airport and reported to be moving northeast. Taxi out was normal. Takeoff roll was as expected. Rotated to climb, resulted in the wind blowing the airplane to the right and aileron deflection to the left did not correct the situation. Fearful of flying low over the ramp, I pulled the nose up to increase climb while maintaining left bank into the wind, praying to get back to runway center. The wind continued to push the airplane to the right towards hangars. Once clear of these hangars and a safe climb established, I turned to course. Continuation of the flight to my destination was without further incident ending in a normal crosswind landing. 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 flight instructor and described the event to him and requested some dual time to discover if my technique for crosswind takeoff was bad or maybe I had developed bad takeoff habits. He agreed and on jun/mon/01 at XA30 we flew 1 hour of dual, made several crosswind takeoffs and lndgs without any problems. The flight instructor loaned me a king video on takeoff and lndgs in crosswind, 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 crosswind when it is blowing towards people or structures in light aircraft. 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.

Title: 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.
