GOL Linhas Aéreas Inteligentes (G3, São Paulo Congonhas) is planning to start proferring maintenance, repair, and overhaul (MRO) services to external customers from 2020 onwards, maintenance director Carlos Alberto Costa said at Aviation Week’s MRO Latin America event.

The facility located at Belo Horizonte Tancredo Neves will initially focus on B737 aircraft. The maintenance hangar can currently fit up to six narrowbodies, including one at a paint station. It is unclear how much capacity of the facility Gol will offer to the market and how much it will continue to use exclusively for internal purposes.

The airline has not yet decided whether it will eventually spin off the MRO unit into a separate company. However, it hopes that by mid-2019 it will have procedures in place that would treat Gol's own aircraft scheduled for maintenance exactly like the future aircraft coming from external customers.

In 2021, the airline plans to expand its services to other narrowbody types, and then tentatively from 2022 it also intends to offer widebody MRO services.

According to the ch-aviation fleets module, Gol is currently a B737-only operator with twenty-four B737-700s, ninety-two B737-800s, and five B737-8s.
