Seattle - Dennis Muilenburg, the Boeing boss, revealed nothing new about the Boeing's long-discussed NMA program at Farnborough Airshow this year.
But internally, Boeing follows a precise timeline for its New Mid-market Airplane that is unofficially dubbed 797 by the industry. Teams in Seattle are working towards a program launch announcement at the Paris Air Show in June 2019 Jon Ostrower reports in his blog The Air Current.
Around $15 billion development cost of the 797 leaves little room for error.
We take the time to do it right,said Muilenburg in the wake of Farnborough Air Show in London last July.
Since 2015, the idea of a mid-sized airliner with 228 to 268 seats is on the Boeing's agenda to fill the gap in the market. Here is the timeline of the Boeing's NMA program according to aviation journalist Jon Ostrower.
December 2018: The deadline for engine offers from manufacturers.
February 2019: Boeing makes its final decision for the engine.
March 2019: Airlines and leasing companies sign preliminary contracts.
June 2019: Program launch of the 797 with the first customers at Paris Air Show
Rolls-Royce is entering the engine tender with Trent's successor Geared UltraFan, according to earlier reports. CFM throws a concept based on the 777X engine GE9X, and Pratt & Whitney wants to offer an upgraded version of its PW1100G that powers the Airbus A321neo.
Boeing's all-new commercial jetliner will have two variants. The 228 seat 797-6X with a range of 5,000 nautical miles, and the 268 seat 797-7X with a range of 4,200 nautical miles. Delta, United, Norwegian and Air Lease Corporation are considered potential customers to receive the aircraft from 2025.
Boeing's European rival Airbus is currently evaluating the feasibility of an "A321XLR" as a competitor to the 797 that could already be available in 2022.
