Narrative:

Prior to my entering concord ccr airspace; I received ATIS information and contacted the tower. Wind conditions had continued to pick up since my departure. I spoke to the controller and received current information and was cleared for runway 19R. Winds were approximately 25 KTS from a heading of 250 degrees and gusting conditions. I made a failed attempt and requested a go around; so I could obtain a better alignment and control. After being cleared by the tower for a second attempt; I had a good alignment and control on my approach to runway 19R. At the numbers; I was approximately 40 ft AGL and encountered a windshear whereby I immediately dropped approximately 30 ft. I added power gaining ground effect control and touched down on the runway. At this point a high gust of wind picked up my right wing and pushed me onto 1 tire towards the left edge of the runway. After applying full rudder and aileron control input and no response to offset the 30+ KT gust I felt the plane was going to continue to go over onto the wingtip and nose. I added power to try to pull out of the failed landing and between the wind; P factor; and airplane position; I was unable to overcome the situation and ground looped the airplane in the grass off to the left side of the runway. This situation arose due to heavy winds with gusts in excess of the plane and my control. Fortunately no one was injured or no property damage occurred. In order to help prevent this situation from occurring again in the future I have scheduled additional ground school and crosswind flight training to become more proficient at situation identify and control.

Title: A MAULE PILOT FLYING AN APPROACH IN CROSSWIND CONDITIONS LOST CONTROL UPON LANDING AND GROUND LOOPED THE AIRCRAFT.

Narrative: PRIOR TO MY ENTERING CONCORD CCR AIRSPACE; I RECEIVED ATIS INFO AND CONTACTED THE TWR. WIND CONDITIONS HAD CONTINUED TO PICK UP SINCE MY DEP. I SPOKE TO THE CTLR AND RECEIVED CURRENT INFO AND WAS CLRED FOR RWY 19R. WINDS WERE APPROX 25 KTS FROM A HDG OF 250 DEGS AND GUSTING CONDITIONS. I MADE A FAILED ATTEMPT AND REQUESTED A GAR; SO I COULD OBTAIN A BETTER ALIGNMENT AND CTL. AFTER BEING CLRED BY THE TWR FOR A SECOND ATTEMPT; I HAD A GOOD ALIGNMENT AND CTL ON MY APCH TO RWY 19R. AT THE NUMBERS; I WAS APPROX 40 FT AGL AND ENCOUNTERED A WINDSHEAR WHEREBY I IMMEDIATELY DROPPED APPROX 30 FT. I ADDED PWR GAINING GND EFFECT CTL AND TOUCHED DOWN ON THE RWY. AT THIS POINT A HIGH GUST OF WIND PICKED UP MY R WING AND PUSHED ME ONTO 1 TIRE TOWARDS THE L EDGE OF THE RWY. AFTER APPLYING FULL RUDDER AND AILERON CTL INPUT AND NO RESPONSE TO OFFSET THE 30+ KT GUST I FELT THE PLANE WAS GOING TO CONTINUE TO GO OVER ONTO THE WINGTIP AND NOSE. I ADDED PWR TO TRY TO PULL OUT OF THE FAILED LNDG AND BTWN THE WIND; P FACTOR; AND AIRPLANE POS; I WAS UNABLE TO OVERCOME THE SITUATION AND GND LOOPED THE AIRPLANE IN THE GRASS OFF TO THE L SIDE OF THE RWY. THIS SITUATION AROSE DUE TO HVY WINDS WITH GUSTS IN EXCESS OF THE PLANE AND MY CTL. FORTUNATELY NO ONE WAS INJURED OR NO PROPERTY DAMAGE OCCURRED. IN ORDER TO HELP PREVENT THIS SITUATION FROM OCCURRING AGAIN IN THE FUTURE I HAVE SCHEDULED ADDITIONAL GND SCHOOL AND XWIND FLT TRAINING TO BECOME MORE PROFICIENT AT SITUATION IDENT AND CTL.
