Aeroman CEO Ernesto Ruiz tells Aviation Week that the El Salvador-based MRO is evaluating its growth options. Its 12 production bays are full and it can either expand in El Salvador, grow outside of its home base or remain the same size. While he would not commit when Aeroman and its investors would decide which choice to pursue, he hopes one of the growth options will win.

Aeroman, which maintains Airbus A320s and Boeing 737s, “would remain focused on narrowbodies” because of the large number operated in the United States. If the MRO decides to broaden its capabilities, the Embraer E170/175 and E190/195 family could be “a possibility on the horizon.”

Even though some widebodies are returning to the U.S. as labor rates in places like China rise, E-Jets would probably be added first, Ruiz says on the sidelines of Aviation Week’s MRO Latin America conference here.

Aeroman’s customers include JetBlue, USAirways, Southwest, TACA, Volaris and Delta Air Lines, the last of which just became a customer in 2013.
