§ 135.168

person may operate a rotorcraft be-
yond autorotational distance from the
shoreline unless it carries:

(1) An approved life preserver

equipped with an approved survivor lo-
cator light for each occupant of the
rotorcraft. The life preserver must be
worn by each occupant while the rotor-
craft is beyond autorotational distance
from the shoreline, except for a patient
transported during a helicopter air am-
bulance operation, as defined in
§ 135.601(b)(1), when wearing a life pre-
server would be inadvisable for medical
reasons; and

(2) An approved and installed 406 MHz

emergency locator transmitter (ELT)
with 121.5 MHz homing capability. Bat-
teries used in ELTs must be main-
tained in accordance with the fol-
lowing—

(i) Non-rechargeable batteries must

be replaced when the transmitter has
been in use for more than 1 cumulative
hour or when 50% of their useful lives
have expired, as established by the
transmitter manufacturer under its ap-
proval. The new expiration date for re-
placing the batteries must be legibly
marked on the outside of the trans-
mitter. The battery useful life require-
ments of this paragraph (b)(2) do not
apply to batteries (such as water-acti-
vated batteries) that are essentially
unaffected during probable storage in-
tervals; or

(ii) Rechargeable batteries used in

the transmitter must be recharged
when the transmitter has been in use
for more than 1 cumulative hour or
when 50% of their useful-life-of-charge
has expired, as established by the
transmitter manufacturer under its ap-
proval. The new expiration date for re-
charging the batteries must be legibly
marked on the outside of the trans-
mitter. The battery useful-life-of-
charge requirements of this paragraph
(b)(2) do not apply to batteries (such as
water-activated batteries) that are es-
sentially unaffected during probable
storage intervals.

ELT standards.

The ELT required

by paragraph (b)(2) of this section must
meet the requirements in:

(1) TSO–C126, TSO–C126a, or TSO–

(2) Section 2 of either RTCA DO–204

or RTCA DO–204A, as specified by the
TSO complied with in paragraph (d)(1)
of this section.

(e)

ELT alternative compliance.

Opera-

tors with an ELT required by para-
