Piper ARCHER II - Emergency Locator Transmitter (ELT)

PIPER AIRCRAFT CORPORATION SECTION 7
PA-28-181, ARCHER II DESCRIPTION & OPERATION.
7.37 EMERGENCY LOCATOR TRANSMITTER*
The Emergency Locator Transmitter (ELT) when installed, is located in
the aft portion of the fuselage just below the stabilator leading edge and is
accessible through a plate on the right side of the fuselage. This plate is
attached with slotted-head nylon screws for ease of removal; these screws
may be readily removed with a variety of common items such as a dime, a
key, a knife blade, etc. If there are no tools available in an emergency the
screw heads may be broken off by any means. The ELT is an emergency
locator transmitter which meets the requirements of FAR 91.52.
A battery replacement date is marked on the transmitter to comply with
FAA regulations, the battery must be replaced on or before this date. The
battery must also be replaced if the transmitter has been used in an
emergency situation or if the accumulated test time exceeds one hour, or if
the unit has been inadvertently activated for an undetermined time period.
NOTE
If for any reason a test transmission is
necessary, the test transmission should be
conducted only in the first five minutes of any
hour and limited to three audio sweeps. If the
tests must be made at any other time, the tests
should be coordinated with the nearest FAA
tower or flight service station.
NARCO ELT 10 OPERATION
On the ELT unit itself is a three position switch placarded “ON,” “OFF”
and “ARM.” The ARM position sets the ELT so that it will transmit after
impact and will continue to transmit until its battery is drained. The ARM
position is selected when the ELT is installed in the airplane and it should
remain in that position.
