The Boeing 737MAX has been grounded around the world after two serious air crashes, CCTV news reported. Boeing has since worked on improving the aircraft's systems, but has been slow to gain safety certification. A number of us airlines announced Monday that they will further delay the launch of Boeing's 737MAX.

Southwest airlines and American airlines both announced Monday that they will delay the launch of the Boeing 737MAX until early March 2020. This is because it is not clear when the model will pass the safety certification. Affected by the grounding of 737MAX, the two airlines cancel more than 300 flights a day.

The Boeing 737MAX was grounded worldwide in March in connection with two fatal air crashes and has yet to make a return to the skies. The evidence suggests that the aircraft's unique "maneuverability enhancement system" automatic stall protection software may be activated when an aircraft's Angle of attack sensor shows an abnormal value, causing the aircraft to dive continuously and become difficult for the pilot to control. Boeing is working on improving the system.

Boeing pilots tested the software through a flight simulation system in June, when engineers nearly completed a software improvement design, us media reported Wednesday. During the test, a software glitch caused the test aircraft to nose-dive, similar to the two previous crashes of the 737MAX. This led to a huge redesign of the entire computer system, a huge increase in the amount of design and inspection work, and a huge delay in the launch schedule of the Boeing 737MAX.

Earlier media reports 6, Boeing recently submitted a software system repair fact sheet, did not pass the United States federal aviation administration and the European aviation safety agency and other regulatory agencies review.
