Boeing 737 MAX operator Lion Air
737 MAX 9
The 737 MAX 9 will replace the 737-900 and has a longer fuselage than the MAX 8. In 2016, Boeing planned to improve its range from 3,510 nautical miles (6,500 km) to 3,605 nmi (6,676 km) after 2021. Lion Air was the launch customer with an order for 201 in February 2012. It made its roll-out on March 7, 2017, and first flight on April 13, 2017; it took off from Renton Municipal Airport and landed at Boeing Field after a 2 hr 42 min flight. It was presented at the 2017 Paris Air Show.Boeing 737-9 flight tests were scheduled to run through 2017, with 30% of the -8 tests repeated; aircraft 1D001 was used for auto-land, avionics, flutter, and mostly stability-and-control trials, while 1D002 was used for environment control system testing. It was certified by February 2018. Asian low-cost carrier Lion Air Group took delivery of the first on March 21, 2018, before entering service with Thai Lion Air. As the competing A321neo attracts more orders, the sale value of a 737-9 is the same as a 2018 737-8 at $53 million.Orders and deliveries
