ET crash ADD NBO

#1 Post by Capetonian » Sun Mar 10, 2019 8:35 am

Sad news, reports of an Ethiopian Airlines crash ADD NBO this morning.

A/C 737 Max 4 months old, ET-AVJ. It had been on the ground for 3 hours after arriving from JNB early this morning. This is the same a/c type as the Lion Air one which crashed, also shortly after departure, in October 2018. I seem to recall there was another (non fatal) serious incident with the same type.

Cape, are you referring to the 737 Max that turned to water plane some where in the Fuji island earlier this year I think?

Have ET lost another 737 about 10 years ago just after take off from BEY? A CFIT with the crew experiencing a vertigo!

Better nip over to TOP for the Metar, seriously though hoping for a good outcome.
When all else fails, read the instructions.

Speaking with great ignorance, but isn't this beginning to sound like the recent Indonesian incident?

A nightmare for the manufacturer?

There are over 200 737MAX versions in service, and over 4000 on order.

I don't think we should be too quick to point fingers at an aircraft flaw, but rather at an inability of the operators to adequately train flight deck crew in the new technology.

No survivors.

Difficult to speculate with so little info. Just going to go across to TOP to find out what caused it.

Here you go folks =))

Hopefully someone will confirm the AvHerald report - giving an altitude of 'FL86' means possibly about 500'AGL!! Flt Level is above MSL, not AGL. Out there you take off at around FL80.

The alleged impact crater picture suggests a frightening similarity to the LionAir 737Max crash.

Surely transition level is 3,000 above airfield elevation. As you say they mean 8,600' above MSL Not FL86.

I'm not sure how ADSB reports vertical position - I have a feeling that at some point after take-off it references to 1013, yet when you 'watch' an approach on FR24 it shows AGL. I have changed the post you quote now as AvH seems to have updated.

If the a/c had been cleared to climb to a FL the crew could have switched to 1013 as well, depending on their SOP.

From Twitter, FR24 raw data - hope it can be read! Note the 7000ft 'jump' after take-off.

Looking at those figures, the a/c appears to have reached at least 1500ft AGL (probable end of flap retraction) and not changed heading much from its departure off R07 There appear to several very concerning ''dives' towards the ground in those figures.

One awaits the Houston CVR to see what caused that pitch change also. Once is happenstance, etc.

Fair to guess that there'll be some very twitchy sphincters in Boeing offices this morning.

On such a new type, for there to be two accidents which bear some resemblance to eachother in such a short space of time.

Perhaps some in the FAA will be wondering how wise is has been for the Administration to so endlessly roll over the type certification from the first variant to this one.

Watch for the Boeing/FAA PR wonks dissociating these two (and the next) accidents from eachother, just like they did for so long and so many times with the 737 elevator woopsies. Watch,also, for endless verbal gymnastics over the definition of the word "type".

Didn't Boeing push for the keeping the original type certification of the 737, as an excuse to keep the number of exits down, so that they could always have a row of seats more that the same length Airbus?

Good points UP.
Does this all not ultimately derive from the legal costs associated with trying to change anything in the US?
