Chicago (dpa) - The US aviation group Boeing has found a new software problem with the banned crisis jet 737 Max, which could make it difficult to re-register. "We are making the necessary updates," said Boeing.
The company works with the US air traffic control agency FAA and keeps customers and suppliers up to date. "Our top priority is that the 737 Max is safe and that all regulatory requirements are met before it can go into operation again."
The 737 Max has been banned from flying around the world since March 2019 because of two crashes that killed a total of 346 people. The decisive cause of the devastating accidents is a faulty automatic control system for the Boeing aircraft.
According to informed sources, the new problem that has now emerged was determined when this update was finalized for this software, which is considered to be the decisive hurdle for re-registration. This could drag the procedure even longer.
In a statement, the US aviation regulator FAA merely stated that the intended restart of the 737 Max would be followed through a thorough testing process in which the authority would cooperate with other international regulators. There is no timetable for when this work will be completed.
The new problem relates to software that is supposed to ensure the correct operation of certain monitors of the 737 Max, it was said from initiated circles. One of these monitors did not start up properly during a test. Investors reacted nervously, dropping Boeing's shares by around two percent in late US trading.
