Analysis

While on a low final approach, the airplane encountered a downdraft over an area of trees. The pilot initiated full engine power; however, the airplane continued to settle until the right landing gear impacted the top branches of a tree. The pilot was able to continue the approach and landed successfully. Once back to the hangar the pilot exited the airplane and discovered that the fuselage had sustained structural damage during the impact.
