Wingview, do you care to read the posts in this thread??
First of all according to the telex from Airbus the incident happened while leaving the engine run up area.
Secondly, earlier somebody made a description why it sometimes necessary to park the aircraft nose in.
Not sure if you are familiar with the Schiphol layout but have a look at the engine test bay at the beginning of runway 27, opposite McDonalds.
This engine test bay is constructed in such a way that regularly during engine test you are facing a wall. Especially when facing South - East. If the brakes would fail and the chocks would not stop the aircraft than you will end up in the same position as the Etihad aircraft.
After having done a fair amount of engine runs in this position myself, and seen other operators do it, i would advise you to be very carefull with appointing blame.
de groeten. CEJM
