Boeing announced that the 737 MAX program has selected a 68-inch fan diameter for the optimized engine design that will provide the lowest fuel burn and operating costs in the single-aisle market. The 737 MAX continues to receive overwhelming acceptance from customers with more than 600 order commitments received to date from eight airlines, up from 496 airplanes from five airlines when the program launched in August. The program is on schedule with internal configuration milestones of the new jet, with a continued focus on engagement with customers and partners to optimize the engine core architecture. Firm configuration for the airplane is scheduled for 2013. First flight for the 737 MAX is scheduled in 2016 with deliveries to customers beginning in 2017.
The new 737 family will be powered by CFM International LEAP-1B engines. The new-engine variant will have 10-12% lower fuel burn than current 737s and a 7% operating cost advantage over the competition. The airplane will have the capacity for increased range while providing better fuel efficiency than today’s already-efficient 737.
