Jakarta - Lion Air considers canceling its existing orders with Boeing. Relations between the Indonesian airline and the American aircraft manufacturer soured after the crash of a Lion Air Boeing 737 MAX 8.

Boeing blames the airline because of the crash while Lion Air points to software problems in the flight control system of 737 MAXs.

Lion Air's co-founder and the former CEO Rusdi Kirana has accused Boeing of attempting to divert attention from recent design changes to the 737 MAXs.

In the preliminary investigation report last week, the Indonesian National Transportation Safety Committee stated that there were problems with the Angle of Attack (AOA) sensors of the aircraft. Due to erroneous data, the nose of the plane plunged. The same problem occurred on a few prior flights as well.

In a statement published by Boeing after the release of the report, the emphasis was on the maintenance carried out in the days before the accident. According to the aircraft manufacturer, one of the AOA sensors was replaced without further information. Boeing claims the maintenance record does not include any information about the installation or calibration of the new sensor.

Boeing is confident about the safety of 737 MAXs despite concerns

Boeing also indirectly questions the actions of pilots during the incident.

Following the crash, Boeing published a service bulletin regarding the MCAS system installed on Boeing's new generation single-aisles.

Lion Air has been a loyal Boeing customer for years. The fleet of the budget carrier consists of 124 Boeing aircraft. There are 249 jets from Boeing in Lion Air's order book waiting to be delivered over time. The catalog value of those orders is about 22 billion dollars.
