A 'no blame' or 'just cause' culture will only work if the country/company in which it is being used understands what a 'no blame/just cause' culture' is. In the UK we regulalry find damage to aircraft that can only have been done on the ramp at the UK airport, and is not reported. In many cases, the perpetrators simply get away with it. Should the 'no blame' apply to such people?
We also get aircraft returning to the UK with un reported damage inflicted down route. Areas round pasenger and cargo doors are favourite.
Some one has done it. Some knows about it. Someone is responsible, but it still happens. 'Ramp Rash' is one the biggest causes of Technical Delays because once damaged, the repair can take a 'long time'.
To willingly know that an aircraft is damaged, to say nothing and the to allow the aircaft to depart in such a condition with no rectifiaction action is not acceptable behaviour for the majority of us.
However there is a minority who do not care or understand and the words 'no blame', just cause, human factors, aircraft safety, duty of care etc etc do not mean a thing to them.
