§ 129.22 Communication and naviga-
tion equipment for rotorcraft oper-
ations under VFR over routes navi-
gated by pilotage.
(a) No foreign air carrier may operate
a rotorcraft under VFR over routes
that can be navigated by pilotage un-
less the rotorcraft is equipped with the
radio communication equipment nec-
essary under normal operating condi-
tions to fulfill the following:
(1) Communicate with at least one
appropriate station from any point on
the route;
(2) Communicate with appropriate air
traffic control facilities from any point
within Class B, Class C, or Class D air-
space, or within a Class E surface area
designated for an airport in which
flights are intended; and
(3) Receive meteorological informa-
tion from any point en route.
(b) No foreign air carrier may operate
a rotorcraft at night under VFR over
routes that can be navigated by pilot-
age unless that rotorcraft is equipped
with—
(1) Radio communication equipment
necessary under normal operating con-
ditions to fulfill the functions specified
in paragraph (a) of this section; and
(2) Navigation equipment suitable for
the route to be flown.

§ 129.23 Transport category cargo
service airplanes: Increased zero
fuel and landing weights.
(a) Notwithstanding the applicable
structural provisions of the transport
category airworthiness regulations,
but subject to paragraphs (b) through
(g) of this section, a foreign air carrier
may operate (for cargo service only)
any of the following transport category
airplanes (certificated under part 4b of
the Civil Air Regulations effective be-
fore March 13, 1956) at increased zero
fuel and landing weights—
(1) DC–6A, DC–6B, DC–7B, and DC–7C;
and
(2) L–1049 B, C, D, E, F, G, and H, and
the L–1649A when modified in accord-
ance with supplemental type certifi-
cate SA 4–1402.
(b) The zero fuel weight (maximum
weight of the airplane with no dispos-
able fuel and oil) and the structural
landing weight may be increased be-
yond the maximum approved in full
compliance with applicable rules only
if the Administrator finds that—
(1) The increase is not likely to re-
duce seriously the structural strength;
(2) The probability of sudden fatigue
failure is not noticeably increased;
(3) The flutter, deformation, and vi-
bration characteristics do not fall
below those required by applicable reg-
ulations; and
(4) All other applicable weight limi-
tations will be met.
(c) No zero fuel weight may be in-
creased by more than five percent, and
the increase in the structural landing
weight may not exceed the amount, in
pounds, of the increase in zero fuel
weight.
(d) Each airplane must be inspected
in accordance with the approved spe-
cial inspection procedures, for oper-
ations at increased weights, estab-
lished and issued by the manufacturer
of the type of airplane.
(e) A foreign air carrier may not op-
erate an airplane under this section un-
less the country of registry requires
the airplane to be operated in accord-
ance with the passenger-carrying
transport category performance oper-
ating limitations in part 121 or the
equivalent.
(f) The Airplane Flight Manual for
each airplane operated under this sec-
tion must be appropriately revised to
include the operating limitations and
information needed for operation at
the increased weights.
(g) Each airplane operated at an in-
creased weight under this section
must, before it is used in passenger
service, be inspected under the special
inspection procedures for return to pas-
senger service established and issued
by the manufacturer and approved by
the Administrator.
