apart from some sensationalist statements a very fact based article.
What's your take on this?

According to the article the A320 problem was tracked down to a software issue. Wonder if it was anything like the problem NASA had with the robotic arm on the space shuttle. It worked fine till some unexpected movement was made and then the software bug appeared.

In our software company ... many years of receiving extremely unwelcome calls from operators of our software Re bugs and problems that couldn't possibly be there!

According to us, that is ... yep, sadly, certain of the operators turned out to be consistently right.
We learned to ignore them at our peril.

There's a nosewheel-pointing probem there, all right.

Oh, and I observed this in 5,000 hours A320 Command time.

Just loved the aeroplane. Known fanatic for the "plastic fantastic".

Neverthless, on several occasions I saw something strange going on.

cheers,
Bill

Hate to tell the writers of this article, but it wasn't just a "software" issue, it was also a hardware issue which was effective for specific serial numbers of the Messier NLG Assembly as an internal component was crapping out. I remember that modification very well (and this has been brought up in multiple threads at this point, including the thread from the TAM incident). Messier said it couldn't be done "in house" (by the airline). With the oversight of the FAA we were able to not only do it "in-house" but in some cases perform the modification of multiple aircraft per night (I believe one night 3 aircraft were completed). To this day, there are upper-ranking crewmembers who have the plaques (which had the removed faulty components mounted on them) from the "NLG MOD" on their desk. The reason only specific serial numbers were effected? Because Messier changed the design of the internal component somewhere along the way, assemblies that already had this new component didn't need the mod done. So the OEM of the NLG even knew there was a flaw with the component  

Also, as stated in the TAM thread from last week, Airbus aircraft are not the only ones who have had gear issues.

At United we've had this happen on the ground after a strut seal replacement on the nose gear. Both times it turned out to be the (6GC) steering feedback . since the steering is all electric it has some failures that defy the imagination. .
