The Boeing 737 Max dilemma never ends. The way out of this, however, becomes more concrete. Because the US air traffic control authority has now for the first time amendments announced that still have to be carried out on the aircraft so that it can be re-registered.

It is now clear that a defect in the flight control software MCAS was one of the main reasons for the catastrophic crashes of the two Boeing planes. Therefore, the FAA requires a fundamental modification of this software, such as futurezone.at reported. In the future, it should also obtain information from more than one sensor.

In addition, the displays in the cockpit are to be used again. The data displayed should be presented in a more understandable manner. The manuals and pilot training courses are also to be revised. In addition, there is an increased risk of short circuits due to the current inadequate cabling of the aircraft. Therefore, the 737 Max now have to be partially rewired. 

The US aircraft manufacturer now has two options: Accept the changes and defects or raise an objection to these findings. You have 45 days for this after publication. In any case, this means: The re-certification will take months.
