What happened
On August 8, 2023, at 10:25 UTC, a Cessna 560, registration LV-WDR, was taxiing toward runway 05 at San Fernando International Airport in Buenos Aires. During the taxi phase, the crew noticed abnormal behavior regarding the aircraft's landing gear system. In response to this perceived malfunction, the crew decided to deviate from the taxiway toward the access area of the AVIASER maintenance facility.
As the aircraft approached the workshop access, the left main gear wheel veered off the taxiway edge and into the adjacent shoulder. The incident resulted in two minor injuries to the occupants, but no fatalities were reported. The aircraft sustained minor damage during the excursion.
The investigation
The Argentine National Directorate for the Investigation of Aeronautical Occurrences (DNISAE) conducted a documentary investigation into the event. Investigators reviewed the operational details of the taxiing maneuver and the technical aspects of the landing gear's perceived malfunction. The investigation focused on the sequence of events leading from the detection of the anomaly to the excursion onto the taxiway shoulder.
