freigthtdriver Nothing more than a minor misunderstanding, no apology required! I can't see how anyone could be seriously offended, just an unfortunate choice of thread title! No big deal.
I do agree that the more people that know the full details of this incident the better, if they are within avaition and could benefit from the outcome of an enquiry. As it is an incident that will cause embarrassment to the operator and the handling agent, if not the manufacturer, and as it does not involve the safety of the travelling public you cannot reasonably expect it to receive much publicity!
If you have ever parked an aircraft on the pasenger stands at Bombay(Mumbai) airport you will know all about the possibility of an aircraft rolling backwards, once parked!
If it is a defective valve or a manufacturing problem you can expect to hear about it via notices from, in this case, Boeing.
When an aircraft rolls away from the chocks it is usually the result of there being no positive brake pressure. This can be caused by a multitude of things that involve both mechanical and human failure, for example, park brake left ON, No chocks, systems depressurised, accumulator pressure dissipates, result? aircraft moves. This example takes no account of mechanical failure that could also influence the situation of an aircraft parked on a stand with either insufficient or no chocks.
There are many, many variations of possible causes for this scenario which is why it is very unwise for anyone to spout "carelessness, irresponsibility" or similar phrases until the full enquiry has taken place.
