14.1 Due to ongoing research and development in the design of WIG craft with a different
geometry to that envisaged during the formulation of these Guidelines, it is important
that these Guidelines do not restrict this progress and the development of new designs.
14.2 A design may be produced which cannot comply with the provisions of these
Guidelines. In such a case the Administration should determine the extent to which the
provisions of the Guidelines are applicable to the design and, if necessary, develop
additional or alternative provisions to provide an equivalent level of safety for the
craft. The full application of the safety assessment and safety management provisions of
these Guidelines at all times remains a fundamental component of such alternative
provisions.
14.3 The foregoing should be considered by the Administration when assessing the
granting of equivalents under the Guidelines.
