What happened
On March 20, 2026, at 13:54 UTC, an Aerolineas Argentinas Boeing 737-800 (registration LV-FUC) was descending to 3,000 feet while proceeding toward the localizer for Runway 13 at Aeroparque Jorge Newbery. Simultaneously, a Bombardier CL600-2B19 (registration LV-BHP) departed from San Fernando airport (SADF) on Runway 05. The business jet had been instructed to maintain its runway heading and climb to 2,000 feet.
Radar data indicated that the LV-BHP subsequently appeared at an altitude of 2,400 feet. In this context, the pilot of the LV-FUC reported receiving a TCAS alert regarding the other traffic. Shortly after, the LV-BHP was observed on the surveillance display maintaining 2,000 feet, and the two aircraft had already crossed paths. Once separation was re-established and the traffic situation verified, the LV-BHP was cleared to proceed toward Ezeiza with a climb to Flight Level 050. The LV-FUC landed safely on Runway 13 at 14:03 UTC.
The investigation
The Joint Safety Board (JST) conducted a desk investigation into this air traffic event, classified as an occurrence without safety effect. The review focused on the sequence of events involving the commercial passenger flight and the non-scheduled business operation. Evidence included radar imagery supplied by EANA showing the moment of crossing and the subsequent separation of the two aircraft. The analysis examined the altitude profiles and instructions given to both crews during the critical phase of the approach and departure.
Findings
Based on the evidence collected, it was concluded that there was no condition of imminent collision between the two aircraft. The investigation established that the separations between the Boeing 737-800 and the Bombardier CL600 remained in compliance with the rules governing the airspace where the event occurred. No damage was reported to either aircraft, and no injuries were recorded.
