The PIC was taking off on runway 32, after lift off and during the initial climb, got to about tree level height and started to hear the stall horn. He then lower the nose to gain airspeed and then increased pitch again to try to climb but the aircraft would not climb. He tried again to do this same process of lowering the nose to try to gain airspeed and attempted to ease the nose up again and that was when the nose dropped (stalled) and the left wing impacted the adjacent grass taxiway. The PIC stated that he experienced some wind shear which caused the aircraft to stall.

During the interview of the PIC he stated that when he left his house

That day he noticed that the wind was a little breezy. When he got to the

Airport he stated that the wind was out of the n-ne but somewhat lite and

Variable with a right cross-wind on his takeoff from runway 32. The

Nearest weather reporting point was approximately 10 miles to the south

Of the airport at krdu. The wind at that site was out of the sw at 12-16

KTS with gusts to 20 KTS. The PIC stated that the run up was normal and

Had normal take off power during the takeoff. The PIC stated that he had

Approximately ¾ of fuel on board and had calculated the w & b to be

Within limits. During the post-accident inspection of the aircraft it was

Verified that all flight controls had continuity and all of the engine

Controls, except the carburetor heat control, were checked and had

Freedom of movement and went to the stops. From all indications during

The post accident inspection the engine was running normally. It is the

Opinion of this ASI that the PIC has had extensive training recognizing

Wind shear and what causes it and due to the conditions, he attempted to

Correct the situation but could not do anything to counter the shear

And/or sink air.
