1.7.1 Where this Code requires that a particular
fitting, material, appliance or apparatus, or type thereof, should
befitted or carried in a craft, or that any particular provision should
be made, the Administration may allow any other fitting, material,
appliance or apparatus, or type thereof, to be fitted or carried,
or any other provision to be made in that craft, if it is satisfied
by trial thereof or otherwise that such fitting, material, appliance
or apparatus, or type thereof, or provision, is at least as effective
as that required by this Code.
1.7.2 Where compliance with any of the requirements
of this Code would be impractical for the particular designs of the
craft, the Administration may substitute alternative requirements
provided that equivalent safety is achieved. The Administration which
allows any such substitution should communicate to the Organization
particulars of these substitutions and the reasons there for, which
the Organization should circulate to its Member Governments for their
information.
1.7.3 The Administration may exempt any craft
from any of the provisions of this Code if the application thereof
would seriously impede research into the development of such craft
engaged on international voyages provided that equivalent safety is
achieved. Any such craft should, however, comply with safety requirements
which, in the opinion of that Administration, are adequate for the
service for which it is intended and are such as to ensure the overall
safety of the craft and which are acceptable to the Governments of
the States to be visited by the craft. The Administration which allows
any such exemption should communicate to the Organization particulars
of same and the reasons therefor, which the Organization should circulate
to the participating Governments for their information.
1.7.4 An Administration may allow the transit
of a craft without passengers or cargo between areas of operation
without a Dynamically Supported Craft Permit to Operate provided that
it complies with safety requirements which are adequate in the opinion
of the Administration for the voyage which is to be undertaken, keeping
in mind the design parameters.
