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.
