Looks like a programmer may have caused the recent Lion Air B737 Max crash killing 189?

737max aircraft have a programme that causes the aircraft to dive in certain situations and Boeing didn't inform pilots until recently the only way to avoid it was to switch off the computer.
Previous B737s required only a pull back on the control column to overide the computer, on Max's that doesn't work.
Reference:ABC news and Flightglobal.

I think you’ll find that a poor safety management system and lax maintenance procedures are behind this accident. There’s a reason why DFAT have issued a ban on government travel on Lion (and not 737MAX operators).

That information relating to the software was released as a safety breifing to operators of the aircraft to let them know of the behaviour of the 737 MAX. This is not admitting that it caused the crash, but instead a safety precaution to reduce the chance of another crash whilst the real reason is being investigated.

When doing work fro DFAT a year ago we were told not to fly Lion if we could help it anyway, so nothing new there.

"Whoppersandwich" is closer to the mark with Lion. I personally would not fly on their Indonesian flagged aircraft flights.It doesn't mean that the 737MAX is un-airworthy from what I can see. I'd still fly on the aircraft, I'd just prefer to be on an airline which has robust safety and maintenance processes.

Jon Ostrower (the editor), has been someone who's writings I've followed since he worked at Flight Global, then WSJ, CNN, and now that he's founded TAC.

A little more reliable than your run-of-the-mill newsrooms that call a 717 a Jumbo, and a a Global Express a commuter jet.

Geoffair is correct. Boeing designed the 737 MAX to provide automatic nose-down trim if the aircraft's computers detect a high angle of attack which could lead to a stall. Numerous pilots have claimed on aviation forums in recent days that there was no warning from Boeing to operators, or training for pilots, about the fact that if pilots countermanded the trim by pulling back on the control column, it would automatically restart after 10 seconds. Pilots on the crashed Lion Air aircraft's immediately prior flight reported a faulty angle of attack indication and had control difficulties. The system was tested on the ground at CGK prior to the crash flight and reported normal. It seems likely that a fault in the aircraft's systems may have presented the pilots with a situation they could not control because Boeing had not drawn attention to the way the aircraft would behave. That is not to say that I would readily agree to travel on any Indonesian airline. I don't think there is an adequate national safety regulatory system or safety culture in Indonesian airlines.
