The Boeing 737 MAX is the fastest-selling plane in company history.
Through September, Boeing has taken orders for 4,783 737 MAX aircraft with 219 delivered to customers.
The 737 MAX currently operates with 40 airlines around the world.

The Boeing 737 MAX entered service in 2017 to great fanfare. The jet is the latest in Boeing's long line of hot-selling 737 family of narrow-body airliners. The 737 MAX has earned praise for its advanced aerodynamics and fuel-efficient engines.

In fact, the 737 remains the best-selling airliner of all time, while the new MAX variant quickly became quickest selling plane in Boeing history. Through September, Boeing has sold 14,985 737s since the 1960s with 4,783 of them the MAX variant. In total, 219 737 MAX aircraft have been delivered to airlines and leasing companies.

In October, the tragic crash of Lion Air Flight JT610 brought the jet back to the forefront the public consciousness. Flight JT610, which killed all 189 people on board, was the first major accident involving the 737 MAX.

On Tuesday, Boeing issued a safety bulletin for airlines operating its new 737 Max airliner in the wake of the crash.

The bulletin cautions operators of the 737 Max that erroneous readings from one of the plane's sensors can cause the aircraft to enter into a sudden dive, Bloomberg reported.

"On November 6, 2018, Boeing issued an Operations Manual Bulletin (OMB) directing operators to existing flight crew procedures to address circumstances where there is erroneous input from an AOA sensor," the company's statement said.

In spite of the tragedy, industry analysts and Boeing's investors remain confident in the company.

"This is a tragedy, but (the safety bulletin) says absolutely nothing about the design of the plane and its major subsystems," TEAL Group aviation analyst Richard Aboulafia told Business Insider.

Boeing stock closed up 1.51% on Wednesday.

The 737 MAX's major US customers include Southwest, American, and United. The plane is also in operation around the world from Air Italy to China Southern.

According to data from Airfleets.net, the 737MAX is currently in operation with 40 airlines around the world.
