Embraer and Republic Airways, operator of the largest Embraer fleet in the world, have signed a contract for the sale of 47 Embraer 175 jets.

The agreement also includes options for an additional 47 aircraft, providing a potential for 94 E175s, which could reach a total value of approximately $4 billion, in 2013 economic conditions, at list price.

The new aircraft will be operated by Republic Airlines, a Republic subsidiary, under American Eagle brand in the American Airlines’ regional network.

The deal is subject to court approval which is expected to occur in the first quarter of 2013.

The E175 will be featured in a dual-class layout, seating up to 76 passengers and the first delivery is scheduled for mid-2013.

“It is significant that our long-time, valued customer Republic Airways – a true innovator in the regional transport business – is the first customer for the enhanced E175,” said Paulo Cesar Silva, president, Embraer Commercial Aviation.

“It’s a perfect example of how our investments in product development make our customers more competitive in their markets.

“The E175 is the most comfortable, technologically advanced and efficient aircraft in its class and it represents the best value for airlines because it also delivers the lowest total operating cost.”

As the leader in the 70 to 120-seat jet segment, Embraer continues to invest in the E-Jets family, which is flown by some 60 airlines from 40 countries.

The Company has begun implementing a series of enhancements to the current generation of E-Jets, including new wingtips, systems optimisation and aerodynamic refinements that will lower fuel burn by up to five per cent.

Republic will be the first customer to receive E175 aircraft with these enhancements. Longer maintenance intervals and component improvements will increase aircraft productivity and lower maintenance costs.
