GCAA Suspends Two Controllers After Loss of Separation Incident in Guyana

The Guyana Civil Aviation Authority (GCAA) has suspended two air traffic controllers following a significant loss of separation incident in Guyanese airspace. The event, which occurred on February 16, 2026, involved a United Airlines flight and a Turpial Airlines aircraft that came within five nautical miles of each other, breaching the required ten-mile separation minimum.

This incident represents a serious breach of air traffic control protocols designed to prevent mid-air collisions. The suspension of the controllers is a standard procedural step while the GCAA conducts a full investigation into the root cause of the separation loss. The flights involved were identified as United Airlines flight UAL860 and Turpial Airlines flight VTU9905. The GCAA's immediate action underscores the critical importance placed on maintaining prescribed safety buffers between aircraft in controlled airspace.

Incident Details and Official Response

According to Guyana's Aviation Minister, Deodat Indar, the required separation in the specific sector of airspace was 10 nautical miles (NM). The breach reduced this safety buffer by half. "They are supposed to have 10 miles between aircraft and something happened and that separation was breached and it became five miles between the aircraft," Minister Indar stated. "So we have suspended the two air traffic controllers and we have launched an investigation into why that has occurred over Guyanese airspace."

The investigation, led by the Guyana Civil Aviation Authority (GCAA), will analyze all relevant data, including radar tracks, flight data recorder information if required, and audio recordings of communications between the controllers and the flight crews of UAL860 and VTU9905. The primary objective is to determine the sequence of events and identify any procedural errors, technical malfunctions, or human factors that contributed to the incident. Suspension pending investigation is a standard industry practice and does not presuppose fault.

Regulatory Standards for Aircraft Separation

Aircraft separation standards are a cornerstone of aviation safety, managed globally under guidelines set by the International Civil Aviation Organization (ICAO). According to ICAO Doc 4444, the standard minimum for en-route radar separation is 5 NM. However, national aviation authorities like the GCAA can and do establish larger minima based on local conditions.

A requirement for 10 NM separation, as was in place during this incident, is often implemented in areas with less comprehensive radar coverage, at longer ranges from a radar station, or as an additional safety buffer in complex airspace. The fact that the separation was reduced to 5 NM, the absolute minimum under ideal ICAO standards, highlights the severity of the breach in an area where a wider margin was deemed necessary by the regulatory body. The investigation will likely focus on why the 10 NM standard was not maintained and what instructions were given to the aircraft by the controllers on duty.

Investigation and Industry Implications

Loss of separation events are treated with the utmost seriousness by aviation regulators worldwide. They represent a failure in the air traffic management system, which is built on multiple layers of redundancy to ensure safety. The GCAA's investigation will be comprehensive, aiming to not only understand this specific event but also to identify any systemic issues that could prevent a recurrence.

For the aviation industry, such incidents serve as a critical reminder of the human element in air traffic control. While technology and automation have advanced significantly, the skill and vigilance of controllers remain paramount. The findings from the GCAA's report will be closely watched by other air navigation service providers to draw lessons and reinforce best practices in their own operations. The investigation is expected to take several weeks or months to complete, after which the GCAA will likely publish its findings and any resulting safety recommendations.

Why This Matters

This incident in Guyanese airspace highlights the persistent risks in air traffic management and the critical importance of adhering to established separation minima. For aviation professionals, it underscores the non-negotiable role of procedural discipline and robust oversight in ensuring safety. The swift response by the GCAA demonstrates a commitment to a strong safety culture, but the event itself is a signal that continuous vigilance and training are essential to prevent potential catastrophes in an increasingly crowded global airspace.
