Why I cannot apply directly to the competent authority of the state of operation?
The authorisation process requires that the authority agrees with the proposal of the operator ensuring the safety of the operation. The level of verification from the authority depends on the level of risk of the operation and on the level of trust on the maturity of the operator. Therefore applying always to the same authority allows to build this trust. Moreover all authorities needs to conduct periodical oversight audits to all operators they issued an operational authorisation or a LUC or received a declaration, being responsible of their national operators is more convenient for both authorities and operators.
