For the second Time within a few months, crashed a new Boeing 737 Max 8 shortly after the Start. At the end of October a machine of the Indonesian crashed budget airline Lion Air, yesterday a machine of Ethiopian Airlines was affected. This is extremely worrying, said Stefan Eiselin, editor-in-chief of aviation portal "Aerotelegraph".
Mr Eiselin, they would rise as an expert in such a machine?
I had a queasy feeling. It is extraordinary that there is a whole new aircraft model, there are two crashes in such a short period of time. Normally, there is not a new plane. Usual individual children are diseases that you corrected afterwards, step for step.
the two failures Are a coincidence? Or is there more to it?
It is too early to say that. There are disturbing Parallels: Both crashes happened a few minutes after the Start. And for both it was a factory new Boeing 737 Max 8. But there are also differences: In the case of Lion Air, the aircraft was repaired on the eve, because the pilots of the previous flight, said the machine voice. According to the preliminary investigation report is a part has not been replaced correctly. This is not to say that the machine was operational. In the case of the machine of Ethiopian Airlines, there was no complaint, neither the pilot nor the mechanic. Also, there were no problems during the previous flight.
China, Indonesia, and Ethiopia have banned the use of the Boeing 737 Max 8. This is excessive, or the world must be the entire fleet grounded?
If you want absolute safety, then this is a viable option. But it's a massive intervention into the freedom of the airlines and Boeing. You do not know whether it is really the aircraft itself or whether it was human error.
How long will it go until the causes of both crashes are under investigation?
Usually there is after a month, a first report that shows the basic outline of what happened. Among other things, be evaluated by using the flight data recorder and the voice recorder, the flight data and conversations in the Cockpit. This first report was published in the case of Lion Air in November. In the case of Ethiopian Airlines which will happen in April. About a year after the accident, there is a comprehensive report. Until the publication of the final report, it can take years. I suppose, in this case, where there is a high pressure on Boeing and the authorities will try to say more in a month than in another case.
it is Investigated whether a new Software for the two crashes is responsible. Are there any suggestions?
When Lion-Air-crash, there were in fact irregularities. The pilots were not or little informed about how the System reacts. If you had known, would you be able to turn it off. Because of their lack of knowledge they not tried the System again and again to override, but in vain. Thus, you have lost a lot of time.
pilot organizations accuse Boeing, the System without any training is introduced and it is up to the airlines even deliberately concealed. This accusation true?
Whether it was aware, you can't say, and there are contradictory statements. Boeing says that this was done in consultation with the authorities, because you have perceived the System as to be of little relevance. And Boeing says the new System should be mentioned in the pilot manual. But there was no active Information of the pilot.
a Lot of African airlines in Europe not to land and take off. How safe are Ethiopian Airlines?
she is a member of the Star Alliance, the Swiss, and Lufthansa belong to. The take flight society, which is bad, and the fractional pilots. Ethiopian also has a very young fleet. Therefore it is considered to be a good Airline by the way, in the meantime, the largest in Africa. (Editorial Tamedia)
