When did the Boeing 737 MAX make its first flight?

The Boeing 737 MAX made its first flight on January 29, 2016.

The first aircraft was a 737 MAX 8, identified by Boeing as aircraft line number 5602. It took off from Renton Municipal Airport in Washington state, beginning the flight-test campaign for the fourth generation of the 737 family.

The MAX introduced larger CFM International LEAP-1B engines and aerodynamic refinements, including split-tip winglets. Because the engines were larger than those on earlier 737 versions, Boeing positioned them higher and farther forward on the wing.

The first MAX delivery went to Malaysia-based airline Malindo Air in May 2017. The 737 MAX later became the subject of worldwide safety reviews after two fatal crashes, leading to a lengthy global grounding and mandated design and training changes.
