§ 121.353 Emergency equipment for op-
erations over uninhabited terrain
areas: Flag, supplemental, and cer-
tain domestic operations.
Unless the airplane has the following
equipment, no person may conduct a
flag or supplemental operation or a do-
mestic operation within the States of
Alaska or Hawaii over an uninhabited
area or any other area that (in its oper-
ations specifications) the Adminis-
trator specifies required equipment for
search and rescue in case of an emer-
gency:
(a) Suitable pyrotechnic signaling de-
vices.
(b) An approved survival type emer-
gency locator transmitter. Batteries
used in this transmitter must be re-
placed (or recharged, if the battery is
rechargeable) when the transmitter has
been in use for more than 1 cumulative
hour, or when 50 percent of their useful
life (or for rechargeable batteries, 50
percent of their useful life of charge)
has expired, as established by the
transmitter manufacturer under its ap-
proval. The new expiration date for re-
placing (or recharging) the battery
must be legibly marked on the outside
of the transmitter. The battery useful
life (or useful life of charge) require-
ments of this paragraph do not apply
to batteries (such as water-activated
batteries) that are essentially unaf-
fected during probable storage inter-
vals.
(c) Enough survival kits, appro-
priately equipped for the route to be
flown for the number of occupants of
the airplane.
