What happened
On September 23, 2024, at 20:51 UTC, an Aerolineas Argentinas flight, operating as AR1881, arrived at Aeroparque Jorge Newbery in Buenos Aires, Argentina. The aircraft, a Boeing 737-800-81D with registration LV-CXT, had completed its scheduled commercial flight from Ushuaia.
As the aircraft was exiting the runway via taxiway "delta" following its landing roll, a mechanical failure occurred. Specifically, the first wheel of the left main landing gear separated from the assembly. The aircraft was carrying 170 passengers at the time of the event, all of whom remained on board without injury.
The investigation
The Argentine Transportation Safety Board (JST) has initiated an investigation into the incident, which has been classified as a serious incident due to the system/component failure. The investigation is currently in the factual stage, focusing on the mechanical integrity of the landing gear assembly. Investigators are analyzing the collected data and are awaiting a technical report from the aircraft manufacturer to further understand the nature of the separation.
Findings
- The primary cause of the incident was the separation of the number 1 wheel from the left main landing gear.
- The event occurred during the taxi phase, specifically while the aircraft was maneuvering off the runway.
- There were no injuries reported among the 170 occupants on board.
