The FAA stated on Wednesday software program repair for the 737 Max that Boeing had been engaged on for the reason that Lion Air crash would take months to finish.
In the meantime, investigators in France have taken cost of the crashed Ethiopian Airways plane’s black containers as they try and uncover what triggered the Boeing 737 Max catastrophe.

How lengthy the evaluation by the BEA will take is dependent upon quite a few issues.
First, the state of the recorders themselves. They’re contained in very sturdy housings designed to resist large forces, and they’re positioned within the rear of the plane the place they might be sheltered from the worst results of an influence.
Nonetheless, they’ll nonetheless be broken, significantly by intense hearth. The investigators might want to extract the reminiscence modules, principally circuit boards lined with reminiscence chips, and perform any essential repairs.
The modules are designed in order that info is unfold throughout a collection of chips. If one half is broken, there ought to nonetheless be useable info elsewhere.
As soon as downloaded, the info additionally must be learn. Surprisingly, it’s not recorded in a regular type – so investigators might want to know how you can make it useable. That can want enter from the airline itself.
If all goes properly, the investigators can have entry to 1000’s of items of knowledge in regards to the plane – not solely what was occurring on the deadly flight itself, but additionally on earlier journeys.
They will even be capable of hear what was occurring within the cockpit, what the pilots stated to 1 one other, and if any audible warnings had been sounding.
