Yes, but only as a professional. The principles of a "just culture" applicable to pilots also apply to engineers, sub-contractors, handling agents etc. Doing otherwise would be both inconsistent and unfair.

a footer I have seen

Experience is learning from mistakes, preferably those suffered by others, friendliness is making sure others know about your mistakes.
ie if you are not open and honest about mistakes, the only way others will gain experience is by making the same mistake.

So if it was the brakes that were faulty, then the last engineer to look at them better have a good answer lined up...
So if you follow youre thinking anything that fails/breaks etc is someones fault. Get a life

No one has said how interested Boeing must be about this. Surely, with 100's of B747's around the world, Boeing would like to know if it is latent problem of the type. Equally, all this chat about blame is so childish. It is disappointing to realise that for some groups of employees it could be an issue. Surely the correct attitude is to have a calm investigation/consideration of any incident so as to understand fully how it happened and avoid any repetition. That is the professional reaction and how it should be in all companies.

Nobody is saying that at all. The post you quoted, and the one prior to that, are simply acknowledging that, rightly or wrongly, that's how today's litigious, cover-your-ass world works.

Gratuitous offensiveness adds nothing to the debate.

Perhaps not. So it could be rephrased as, say:

"Change your attitude towards emphasising the need to get the job done, and away from the need to avoid being blamed for anything."

The first may be shorthand for the second.

The aircraft (PH-BFN) did a test flight this morning, after repairs. It is on its way to JFK as we speak.
Apparently took a while to fix it (5 days)

Anyway back to the basics, without knowing anything other than media reports, veering off the runway after autoland etc has happened on this and other types before and probably will again. Which is why the more modern Boeing and AB widebodies have evermore monitoring and automation of components in these systems compared with that generation of a/c to hopefully prevent it.

"….veering off the runway after autoland etc has happened on this and other types before and probably will again."

While not quite apples & apples, but wishing to inject a lighter moment into this discussion:

Tech log entry: "A/c difficult to taxi off the runway." Reply: "Try disconnecting the autopilot after autoland."

Must have been a long long fatiguing flight.

While I fully agree that a safety culture is about finding causes and preventing recurrence and not about apportioning blame, some people seem to think this culture still exists. It was a hard earned culture that did well for a couple of decades, but it is long dead. MBA managers with no experience in the front lines of aviation and greedy investors saw to it that crews and engineers are blamed for everything so that company policies, procedures and equipment get off the hook, and is seems to me that authorities and often investigators are complicit as otherwise they would face questions over why they didn't perform their regulating role properly. Cash is king, and the minions are the scape goats.

After disconnecting autopilot for manual roll out a technical malfunction occurred?

"The crew advised air traffic control, that after disconnecting the autopilot on the ground for a manual roll out a technical malfunction occurred that caused the aircraft to veer sharply to the right."

(source: AvHerald)

Interesting malfunction. How this can happen?

Yeah, like each brake gets a full overhaul every transit. After initial assembly, then fitment, the routine attention they would receive would be a general visual inspection by pilot and gnd staff on walkaround (depending on the airline operational procedures).

There is only so much you can assess from looking at the ass end of a brake.

The clown that made that statement has obviously never been involved with aircraft in any kind of professional capacity. A visual inspection is for wear.leaks and general condition. It will not predict future brake control valve,anti skid system or auto brake failure - I doubt the gentleman concerned has ever heard of these components.l

The problem was a metering valve in the nose gear steering unit according to company mail. The valve has been replaced, test was performed and problem was solved.

Phiggs:

Looking at the second photo, it appears that the steering was central, but the nose wheel ploughed the grass to the right,

Look again.

The spaced tyre tracks indicate that the nose-wheel was steering to the right as it exited the runway. The nose-wheel was then centered, once the aircraft was stopped.

It therefore looks like a nose-wheel steering failure.

That depends entirely on the nature of the fault. Things break independent of how it was installed or serviced. Then there's things like bird strikes and (especially for landing gear components) FOD on the runway. (Indeed, that's what downed Concorde AF4590.)

I don't understand the mindset that is so quick to condemn people.

I fly for KLM, I fly the 747!!!

IT WAS A NOSEWHEEL STEERING METERING VALVE PROBLEM!!!!!

It doesn't LOOK like a nosewheel steering metering valve problem, it WAS a nosewheel steering metering valve problem!!

It wasn't a BRAKE problem, it was a nosewheel steering metering valve so no engineer should have an answer lined up about the brakes!!!!

Enough speculation as to what was the cause, IT WAS A NOSEWHEEL STEERING METERING VALVE PROBLEM!!!!!

@Flyburg

Quick question. Do you think it could have been a Nosewheel Steering Metering Valve problem ?
