In a rare public dispute between the planemaker and one of its biggest customers, the head of PT Lion Mentari Airlines has threatened to cancel an order for billions of dollars worth of jets because of what he says is Boeing’s unfair reaction to the crash.
Boeing and US aviation regulators are considering whether to add a software fix to the 737 Max. Three US pilots’ unions have raised concern about what they say is a lack of information provided by Boeing on the safety system.
The purchase offers Europe's Airbus a chance to trigger the defection of a Boeing customer in a key market but Boeing is seen s the front-runner to win the order and retain the 737 operator's business, the sources said.
Flight-tracking data before the two-month old Lion Air jet crashed showed the plane was varying its altitude and speed, a possible indication that the pilots weren’t getting accurate information from the aircraft’s air-pressure sensors.
