For those not deaf to Logic & common sense:

In Visual conditions, faults in airspeed data alone are not sufficient to cause pilot's loss of control

And no one has said that it could cause a loss of control, or that it was the only factor involved in the accident.

My one consolation with all your abusive comments is that they prove how little you actually know about aviation and how dangerously limited your imagination is.



Boeing are about to publish an advisory corroborating my theory

Boeing about to issue safety warning for B737MAX




Boeing Co. is preparing to send a bulletin to operators of its new 737 Max models warning that erroneous readings from a flight-monitoring system can cause the planes to aggressively dive, said a person familiar with the matter.

This is the issue that downed JT610

The only person being rude is you and how can you be so sure that's the issue?

Agreed. sy.gunson has an "attitude" problem.

What's with these shady as hell captioned images as well?

Not saying he's wrong, the theory is interesting, but damn, they're not doing themselves any favours.

It just looks like the stuff you'd find on twitter and Facebook where so called experts tell you what's happened before any official announcements.

Bit of an update just popped up on Reuters twitter feed.


Boeing Co is planning to send a bulletin to 737 MAX jet operators as soon as Wednesday advising them of the procedure for dealing with erroneous cockpit readings that could cause a dive, a person briefed on the matter told Reuters. The advice is based on preliminary information gathered in the investigation of a Lion Air flight that crashed in Indonesia last week killing all 189 on board, the person said. Experts say the notice could be about the “angle of attack”, which is the angle of the wing relative to oncoming air stream, a measure that indicates if a plane is likely to stall. Indonesian accident investigators said on Monday that an airspeed indicator on the crashed jet was damaged for its last four flights, but U.S. authorities responded cautiously to suggestions of fleet-wide checks. Bloomberg News reported the planned bulletin from Boeing earlier on Tuesday and said the manufacturer would alert pilots to follow existing procedures to address the issue. Boeing declined to comment.

The real issue that needs to be addressed is why a known faulty jet was actually flying.

They were aware of a continuing problem and yet $$$ came before safety.

Lion Air are at fault. They disregarded the aircraft's warnings.

The bulletin covers the AoA sensor.

www.flightglobal.com...

ETA: Per Boeing, in manual flight, the erroneous AoA readings can result in the pitch trim automatically selecting nose down in increments up to 10 seconds. It can be stopped and reversed easily, but can continue 5 seconds after the trim switch is released.

The FAA issued an emergency Airworthiness Directive for the Max. It states that per a determination by Boeing, a single erroneous input from one of the AoA sensors can lead to repeated nose down inputs by the trim system, as well as the errors seen on this aircraft over multiple flights.

thanks to all for updates

media establishment walked away no longer interested

wonder how much is the plane type, how much that specific plane, and how much is Lion Air

That's the big question. There haven't been any reports of issues from other operators, but this aircraft was built during the worst of Boeing's production problems this past summer.

Maybe it's only a bad AoA sensor and maintenance hsn't been knowledgeable enough to figure it out.

Two sensors only on the aircraft?

You mean it wasn't a fleetwide -uncommanded-spoiler-deployment-bug? I'm shocked.

I'm sure it'll just be Boeing trying to cover their ass to save billions in sales by claiming it's an easy fix and not a design flaw.

Or something.

If it was really a fleetwide high-probability problem, they'd be tripping over themselves to ground the fleet for liability reasons.

They're more than happy to blame pilots, maintenance programs, etc when there is the slightest questionable deviation from norms in customer behaviour though.

Of course they would. When has that ever stopped wild speculation about design flaws though.
