(a) Except as provided in paragraphs
(e) and (f) of this section, no person
may operate a U.S.-registered civil airplane 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 commercial 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 section, there must be attached to the airplane 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 TSOC91 may not be used for new installations.
(b) Each emergency locator transmitter required by paragraph (a) of this
section must be attached to the airplane in such a manner that the probability 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 paragraphs (a) and (b) of this section must
be replaced (or recharged, if the batteries 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 approval.
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 batteries (such as water-activated batteries) that are essentially unaffected
during probable storage intervals.
(d) Each emergency locator transmitter required by paragraph (a) of this
section must be inspected within 12
calendar months after the last inspection 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 emergency locator transmitter is to be installed; and
(2) Ferry an airplane with an inoperative emergency locator transmitter
from a place where repairs or replacements cannot be made to a place where
they can be made.
No person other than required crewmembers may be carried aboard an airplane being ferried under paragraph (e)
of this section.
