§ 91.207
Emergency locator transmit-
ters.
(a) Except as provided in paragraphs
(e) and (f) of this section, no person
may operate a U.S.-registered civil air-
plane unless—
(1) There is attached to the airplane
an approved automatic type emergency
locator transmitter that is in operable
condition for the following operations,
except that after June 21, 1995, an
emergency locator transmitter that
meets the requirements of TSO-C91
may not be used for new installations:
(i) Those operations governed by the
supplemental air carrier and commer-
cial operator rules of parts 121 and 125;
(ii) Charter flights governed by the
domestic and flag air carrier rules of
part 121 of this chapter; and
(iii) Operations governed by part 135
of this chapter; or
(2) For operations other than those
specified in paragraph (a)(1) of this sec-
tion, there must be attached to the air-
plane an approved personal type or an
approved automatic type emergency
locator transmitter that is in operable
condition, except that after June 21,
1995, an emergency locator transmitter
that meets the requirements of TSO-
C91 may not be used for new installa-
tions.
(b) Each emergency locator trans-
mitter required by paragraph (a) of this
section must be attached to the air-
plane in such a manner that the prob-
ability of damage to the transmitter in
the event of crash impact is minimized.
Fixed and deployable automatic type
transmitters must be attached to the
airplane as far aft as practicable.
(c) Batteries used in the emergency
locator transmitters required by para-
graphs (a) and (b) of this section must
be replaced (or recharged, if the bat-
teries are rechargeable)—
(1) When the transmitter has been in
use for more than 1 cumulative hour;
or
(2) 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 replacing
(or recharging) the battery must be
legibly marked on the outside of the
transmitter and entered in the aircraft
maintenance record. Paragraph (c)(2)
of this section does not apply to bat-
teries (such as water-activated bat-
teries) that are essentially unaffected
during probable storage intervals.
(d) Each emergency locator trans-
mitter required by paragraph (a) of this
section must be inspected within 12
calendar months after the last inspec-
tion for—
(1) Proper installation;
(2) Battery corrosion;
(3) Operation of the controls and
crash sensor; and
(4) The presence of a sufficient signal
radiated from its antenna.
(e) Notwithstanding paragraph (a) of
this section, a person may—
(1) Ferry a newly acquired airplane
from the place where possession of it
was taken to a place where the emer-
gency locator transmitter is to be in-
stalled; and
(2) Ferry an airplane with an inoper-
ative emergency locator transmitter
from a place where repairs or replace-
ments cannot be made to a place where
they can be made.
No person other than required crew-
members may be carried aboard an air-
plane being ferried under paragraph (e)
of this section.
(f) Paragraph (a) of this section does
not apply to—
(1) Before January 1, 2004, turbojet-
powered aircraft;
(2) Aircraft while engaged in sched-
uled flights by scheduled air carriers;
(3) Aircraft while engaged in training
operations conducted entirely within a
50-nautical mile radius of the airport
from which such local flight operations
began;
