The US aircraft manufacturer wants to set up the revised Software for the 737-Max machines in the coming weeks. They wanted to ensure "that we take the time to do it right," said Boeing on Tuesday night.
The U.S. aviation authority FAA has requested from the aircraft manufacturer Boeing, improvements to the software update for machines of the type 737 Max 8. It is additional work, it should be "" necessary, explained to the FAA on Monday. The authority will expect to get the final software package "in the coming weeks," submitted.
"The FAA will not allow the Software for an Installation, before the authority is happy with the template", - said the aviation supervision. This could mean that the machines must remain much longer on the ground than expected.
crashes with Similarities
After the crash of two Boeing 737 Max 8 within five months of the year, all aircraft of this type are no longer allowed to stand out in the world. 10. March, a 737 Max 8 of Ethiopian Airlines crashed shortly after takeoff in Addis Ababa. All 157 people on Board were killed.

The System pushes the nose of the aircraft down when it runs out demolition of a flow.
System overloaded pilot
In the case of Indonesia crashed machine was discovered, a Sensor of the System, apparently, an incorrect pitch angle. While the MCAS pushed the nose of the aircraft then down, trying to get the pilots desperately to pull the machine upwards.
Last week, presented Boeing then Changes to the control software. The MCAS should not make repeated corrections, when the pilots try to be in control of the machine to recover. In addition to turning off the System automatically when the two Sensors provide the so-called angle of attack measure, conflicting data.
Boeing is hoping for a swift approval of updates to the software in order for the 737 Max 8 can start again. The FAA announced on Monday, to want the software update to a "strict safety check". The authority was last advised due to accusations of a too great proximity to Boeing in the criticism. (chk/AFP/sda)
