MIAMI — Brazilian airframer Embraer is readying the assembly of the first wing for its E195-E2 jetliner, another milestone towards its first flight by the second half of 2017.

The wings of the EJets-E2s are assembled at Embraer’s main factory in São Jose dos Campos, Brazil, and include wing spars and skins manufactured at the company’s Evora plant located in Portugal.

According to Embraer, the new wing structure will weigh less, cost less to maintain and is sized for each aircraft to optimize load efficiency. This, together with the Pratt & Whitney Geared Turbo Fan (GTF) PW1000G powerplant will not only improve fuel burn, but also will reduce carbon footprint and noise levels.

The range of the E2 has also been significantly increased over the current generation. In the case of the E195-E2, the range was increased by 150 nautical miles (278km), to cover distances of up to 2,450 nautical miles (4,540km).

To date, the E-Jets E2 program has received 272 firm orders and 398 options. Last August, a third E190 E2 joined the flight test campaign, with a fourth aircraft, fitted with a cabin interior, to be incorporated early next year, which will be used to evaluate the passenger comfort and internal noise levels.

According to Embraer, the E-Jets are being operated by about 70 customers in 50 countries. With over 50% market share, they are the global leader in the segment of up to 130 seat aircraft.

The first E195-E2 is planned to be delivered in 2019.
