Smoke was reportedly seen coming from the air traffic control tower at ANR Robinson International Airport in Tobago on Tuesday, triggering a fire alarm and forcing staff to evacuate the building.
Multiple sources confirmed that the fire alarm was activated.
The evacuation has affected operations at the airport, with Caribbean Airlines flight BW1520 on the domestic airbridge grounded.
Another source told Guardian Media that a team from Trinidad is expected to travel to Tobago to address the issue.
The air traffic control tower is responsible for controlling aircraft approaching to land at the airport, while air traffic control at Piarco can manage aircraft flying across the area.
A source explained that the tower’s control extends to roughly a four-mile radius around the airport, making it necessary for someone to be stationed there unless contingency arrangements, such as air-to-ground radio communications, are put in place.
Guardian Media also understands there was an issue with the tower a couple of weeks ago which resulted in delays, although that problem was subsequently resolved.
Guardian Media contacted the Airports Authority of Trinidad and Tobago for an official comment and is awaiting a response.
Minister of Civil Aviation Eli Zakour was also contacted on Tuesday. He asked that questions be sent via WhatsApp but had not responded up to publication.
