Embraer expects to expand its Super Tucano customer base with the addition of three operators.

The deals, set to be announced March 28, include two already in the company backlog as undisclosed customers, and one genuine new buyer. The deals could include the first African state to buy the light-attack aircraft.

Embraer has been pursuing several campaigns in Latin America, Africa and Asia. Guatemala is seen as a potential new buyer. Indonesia, already a buyer of eight Super Tucanos, is considered likely to buy more.

The deals come as Embraer awaits word from of the U.S. on plans for the Light Air Support aircraft for Afghanistan. The follow-on procurement strategy has not been set following the botched U.S. Air Force procurement program. The service initially awarded the contract to a Sierra Nevada/Embraer team, but has since voided the award, citing concerns with its source-selection process in the wake of protests from losing bidder Hawker Beechcraft. A review of the shortcomings has been extended, with the investigation now expected to be completed in early April.
