Where it is satisfied by lightweight survey, weighing or
                           other demonstration that the lightweight of a craft is closely similar
                           to that of another craft of the series to which 2.7.1 has been applied, the Administration may waive the requirement
                           of 2.7.1 for craft to be inclined.
                           In this regard, a craft which lies within the parameters of 2.14.1, when compared with a craft of
                           the series which has been inclined, shall be regarded as being closely
                           similar to that craft.
