What happened
On July 29, 2020, a Learjet 60, registration LV-CIO, was performing a medical transport flight from San Fernando International Airport to Resistencia International Airport in Chaco, Argentina. During the approach phase of the flight, the crew received an indication within the cockpit suggesting that the right-side landing gear was in the up position.
After passing the control tower, the pilot was unable to verify the actual physical position of the landing gear. Consequently, the pilot elected to maintain a safe altitude and initiated the standard emergency procedures required for landing gear extension and locking. Following the execution of these procedures, the aircraft completed a normal landing at the aerodrome.
The investigation
The Argentine Transportation Safety Board (JST) conducted a technical review of the event. The investigation focused on the system/component failure that triggered the cockpit indication. Investigators examined the aircraft's condition following the incident and the specific circumstances at the Resistencia International Airport.
Findings
- The primary issue involved a system or component failure that provided an incorrect landing gear position indication to the crew.
- There were no injuries to the two occupants on board.
- The aircraft sustained no damage during the event or the subsequent landing.
- The incident did not pose a threat to operational safety, leading the JST to conclude that no further investigation was necessary.
