Accident Sequence
At 0743 local time, a training aircraft departed Zurich-Kloten's runway 28 on a local training mission. The crew consisted of an instructor and three student pilots. During the initial climb, the instructor made a slight turn to the right and continued flying at low altitude. The aircraft subsequently contacted tree tops, stalled, and crashed in a wooded area in Regensberg, approximately 8 km northwest of the airport. The debris field extended over more than 200 meters. All four crew members were killed.
Investigation Findings
The official investigation determined that the instructor decided to turn right after rotation instead of following the published procedures, which required a left turn. The reason for this decision could not be determined. Due to insufficient height, the aircraft struck tree tops, causing a stall and subsequent crash into a dense wooded area. The lack of visibility caused by foggy conditions was considered a contributing factor.
