Incident Overview
The aircraft departed from Trieben airfield (ICAO: LOGI) with one pilot and four skydivers on board, including two tandem passengers. During a climb to flight level 130 (FL130), under initially good visibility and with ground contact, the aircraft unexpectedly entered a rapidly forming cloud. This resulted in a sudden and complete loss of external visual reference.
Evasive Maneuver and Uncontrolled State
The pilot initiated an evasive maneuver by attempting a 180-degree turn, but the maneuver was unsuccessful. Subsequently, the aircraft entered an uncontrolled flight condition. Despite the loss of control, the aircraft eventually landed back at Trieben airfield. No injuries were reported among the occupants.
Structural Damage
Post-landing inspection revealed structural damage to the aircraft, particularly at the connections between the wings and the struts. The extent of the damage was limited to these areas.
Probable Cause
No probable cause was stated in the report.
