The persons responsible for the security and rescue operations and the prosecution authorities shall have unlimited access.
The representatives of the competent federal authorities, authorised persons from a foreign state and other persons who can establish a prima facie legal interest in the outcome of the safety investigation shall be granted access provided the safety investigation activities are not disrupted thereby.43
