History

Before 2000 (millennium year)
The company was established in 1984 as Garuda Maintenance Facilities Support Center. In seven years, funded entirely by the Indonesian government, it had spent US$200 million, of which 63% was used to import hi-tech machinery and equipment. In 1996, it became a SBU changing its name to Garuda Maintenance Facilities AeroAsia, or GMF AeroAsia in short.

After 2000
In August 2002, it split off from PT Garuda Indonesia.

In January 2007, PT Garuda Indonesia announced it would sell a minority stake of GMF AeroAsia in April 2007. Other subsidiaries, PT Aerowisata, PT Abacus Distribution System and PT Gapura Angkasa would be sold completely as Garuda Indonesia does not consider them as "core business". GMF AeroAsia has recently concluded a restructuring as part of the company's strategic development visions embodied in 'The Global Challenge', a fifteen-year 'voyage' plan.

Currently, it is certified in many countries and serves many airlines. It has three partners; KLM Engineering & Maintenance, Swiss Air and Global Aviation USA
In September 2008, KLM attempted to buy shares in GMF, but were turned down. The intention is to release the shares publicly and KLM were told they were free to buy shares at that point. In 2009, GMF AeroAsia's biggest clients are parent Garuda followed by Lion Air, but as 2015, GMF AeroAsia's biggest clients are its parent company Garuda Indonesia with its low-cost arm Citilink followed by Sriwijaya Air. Lion Air itself as previous second biggest client of GMF already sets up their own maintenance repair and overhaul in Batam called Batam Aero Technic and now only uses GMF when unable to bring their aircraft to Batam.
