Is Boeing's huge software bug finally fixed? The manufacturer is claiming that the software fix for the 737 MAX is complete. Boeing is now asking the Federal Aviation Administration (FAA) for approval to move forward and have its fleet certified following a mass grounding of the model.

It has been revealed that Boeing has officially submitted a pilot-training plan to the FAA. In addition, Boeing is now in the process of scheduling a test flight that will potentially allow the 737 MAX to be certified and cleared for flight again. All of Boeing's 737 MAX planes were grounded this spring following a pair of high-profile crashes within a span of just five months. One of those crashes was the tragic Lion Air crash that claimed the lives of 189 people after plunging into the Java Sea. Airlines have been forced to craft their summer schedules without using the popular 737 MAX. Some critics feel that the grounded planes should never be allowed to fly again.

How likely is it that Boeing's 737 MAX will be cleared for flight once more? The FAA plans to host a meeting with regulators from around the world on May 23. The meeting is set to take place in Fort Worth, Texas. It will be up to each nation to grant independent approval to Boeing before the 737 MAX can be cleared for future flights. However, there's a good chance that both airlines and airline customers will have a hard time trusting the 737 MAX if and when it does return to the skies.

What's more, most passengers won't fly on 737 MAX planes this summer even if the plane does receive approval. Airlines like American Airlines and Southwest developed their schedules for the busy summer season without including the 737 MAX. Both airlines have MAX-free schedules until August. However, it is possible that 737 MAX planes could be used as backup planes by some airlines if the model does receive approval before the end of summer.
