The US aviation authority FAA expects that they can lift the flight ban for Boeing's medium-haul jet 737 Max later this year.
The 737 Max will definitely fly again before the end of the year, said the FAA security expert Ali Bahrami the news agency Bloomberg on Wednesday in Cologne. However, an exact point in time can not be named because the security-relevant changes to the aircraft type would still be examined.
After the two crashes within a few months with 346 dead Max will resume her regular service only "if we are convinced that she is safe," said Bahrami. In May, reigning FAA chief Daniel Elwell took the potential deadline for the no-fly plan even further: if it took a year for the agency to do everything it could to get the planes flying again, "then it should be so".
According to Bahrami, specialists are currently taking a closer look at the aircraft customization, flight design software and design, as he said at a joint FAA and European Aerospace Authority [EASA] conference.
Especially the software MCAS is suspected to be responsible for the crashes. The on-board computer should have pushed down the nose of the Boeing. The crew was no longer able to correct the mistake. The FAA's approval of the aircraft itself is also criticized. Many foreign authorities, such as EASA, are therefore involved in the current review.
