From the RAH contract, Article 21, "New Aircraft"
6. Nothing set forth in this Article shall prevent the Company from introducing
a new aircraft type into revenue service before agreement is reached over
the rates applicable to that aircraft, as long as the pay rates assigned to
such aircraft type are not less than the rates provided by this Article or the
principal Agreement for aircraft with similar power plant (turboprop or jet)
and seat range that either includes the number of seats in the new aircraft
type or has a seat range not greater than the number seats in the disputed
aircraft. If the aircraft is smaller (less seats) than any other aircraft for
which pay scales have been established by this Agreement then, subject
to the provisions of this article, the Company will establish a rate for the
new aircraft until a negotiated rate has been agreed to by the parties. The
negotiated rate will be retroactive to the implementation of the new aircraft
type.
