The aircraft owner was on board as a passenger. The owner and the second passenger stated that on final approach the air was very turbulent, especially when the aircraft descended below the tops of the trees which surround the airport. The aircraft owner stated that he thought the aircraft encountered a low level wind shear caused by the trees.
