Incident
While en route at 7,500 feet, the pilot maneuvered the airplane to avoid flying into clouds. As he maneuvered, he entered an area of severe turbulence. During the event, the airplane lost about 4,000 feet of altitude. The pilot recalled hearing the airframe pop and felt the airframe twist.
Damage and Return
After regaining control of the airplane, the pilot noticed some deformation to the wing assembly and airframe. Determining the damage, the pilot elected to return to his departure airport. Upon arriving at the airport, the pilot discovered that the landing gear would not extend.
Emergency Landing
The pilot executed an off-runway emergency landing in a grassy area parallel to the southwest runway.
Pilot Report
During a subsequent conversation with the pilot, he reported that he entered the area of turbulence about one mile from a cloud buildup. Visual weather conditions prevailed below the broken cloud layers.
