SECTION I
GENERAL INFORMATION
1.1 SCOPE
This manual contains information necessary for the installation, test and operation of
the model AK-451, Emergency Locator Transmitter, manufactured by Ameri-King
Corporation, California, U.S.A.
1.2 OVERVIEW
1.2.1 Description
The Ameri-King AK-451-( ) Series is a FAA TSO’d approved, EASA ETSO’d
approved, 406 MHz ELT Emergency Locator Transmitter, Types (AF) Automatic
Fixed, (AP) Automatic Portable, (S) Survival. It transmits aircraft GPS/NAV position
data, immediately and accurately, on triple (406 Satellite /243 Military /121.5
Civilian) MHz frequencies. The supreme advantage feature is the aircraft GPS/NAV
Latitude / Longitude exact position shall be transmitted, within 1 minute, on the very
first burst, without waiting for a Polar Orbiting Satellite (could be up to 4 hours).
Enhance the accuracy significantly, for the ground search area, from 1-2 kilometers
(non GPS/ NAV Position) to 22 meters typical (with GPS/NAV Position). Having a
triple frequency insures your distress message reaches both NOAA Satellite
Operation and US Air Force AFSR Ground Operation, Search and Rescue Team, with
100% fully confidence, due to transmitting on both 243.0 MHz Military and 121.5
MHz Civilian bands, for immediate ground search dispatch, narrowing the searching
time.
The AK-451 ELT Emergency Locator Transmitter is micro controller based
equipment. It is extremely reliable equipment, designed to meet TSO-C126 and TSOC91A requirements, batteries operated and self contained.
The ELT Emergency Locator Transmitter is designed only for emergency use. The
model AK-451 may be used as one or more of the following ELT types:
a. Automatic Fixed-ELT (AF):
The ELT (AF) is designed to be permanently attached to the aircraft before and after a
crash. Aural and flashing light monitors are provided to alert the flight crew that the
ELT has been activated and is transmitting. It is designed to aid the Cospas-Sarsat
satellite and SAR teams in locating a crash site.
The model AK-451 (AF) consists of an ELT main unit, an aircraft-fixed antenna,
coaxial cable assembly, remote switch unit, interconnect wiring assembly, a T-adapter
connector, an audible buzzer monitor, a mounting tray, and clamp holders.
The ELT (AF) has an automatic activation G-Switch. It is activated automatically
upon a crash or manually operated.
15
b. Automatic Portable-ELT (AF) (AP) with dual antennas:
The ELT (AF) (AP) is designed to be rigidly attached to the aircraft before the crash,
but readily removable from the aircraft after a crash. It functions as an ELT (AF)
during a crash sequence. The aircraft mounted antenna may be disconnected and a
portable antenna (mounted on the ELT mounting tray) is then attached to the ELT.
All mentioned procedures require no tools. Flashing light indicator on the ELT is
provided to alert the user that the ELT has been activated and is transmitting. The
ELT can be tethered to a survivor or a life raft. It is designed to aid the Cospas-Sarsat
satellite and SAR teams in locating the crash site or survivor(s).
The model AK-451 (AF) (AP) consists of an ELT main unit, an aircraft-fixed
antenna, a portable antenna, coaxial cable assembly, remote switch unit, interconnect
wiring assembly, a T-adapter connector, an audible buzzer monitor, a mounting tray,
clamp holders and portable soft case..
The ELT (AF)(AP) has an automatic activation G-Switch. It is activated
automatically upon a crash or manually operated.
If for any reason, a fixed mounting is not required, the ELT (AF)(AP) can be used as
a Portable Device, due to it ‘s manual operated hand use Portability. Check Local
and/or national regulations for this issue.
c. Automatic Portable-ELT (AP) with integral antenna:
The ELT (AP) is designed to be rigidly attached to the aircraft before the crash, but
readily removable from the aircraft after a crash. It functions as an ELT (AF) during
a crash sequence. All mentioned procedures require no tools. Flashing light indicator

SECTION II
INSTALLATION AND TEST
2.1 UNPACKING AND INSPECTING EQUIPMENT
Handle with extreme care when unpacking the equipment. Visual inspection of the
equipment for evidence of damage incurred during shipment. Any claim should be
promptly filed with the transportation company. Save the shipping container to
substantiate the claim. Retain the container and packaging material for possible
future use.
2.2 MECHANICAL INSTALLATION
The ELT is designed with the installer in mind. All accessories, which are required
for complete ELT system installation, are provided, including Mounting Tray, Clamp
Holder, Coaxial Cable Assembly and Wiring Cable Assembly.
Because of the critical nature of an ELT, it is very important that the installation be
performed according to the following instructions. Installation of the ELT is
somewhat unique, as is the installation of any TSO-C126 and TSO-C91a ELT; it
requires experience in sheet metal work and avionics. Only licensed technicians
should install the ELT.
Many problems associated with the older ELTs were due to poor installation.
Therefore, duplicating a previous ELT installation with the AMERI-KING ELT may
not be acceptable.
Installations must be made by qualified personnel in accordance with FAA
regulations. Duplicating a previous installation may not be acceptable. Refer to the
Department of Transportation Regional ACO for detailed information.
Please refer to FAA AC 43.13 for guideline.
RTCA DO-182 recommends:
"All ELT system components which must survive a crash intact, should be attached to
the airframe in such a manner that the attachment system can support a 100g load ...in
the plus and minus directions of the three principal axes of the aircraft."

Note:
Installation in a pressurized aircraft constitutes a major modification. Consult the
Department of Transportation Regional Officer before proceeding.
Note:
Aircraft manufacturers may also have guidance on ELT installation; refer to and
follow any applicable Type Approval or STC data for your aircraft. If located outside
of the US, follow all applicable regulations for your national authority.
By signing either the aircraft logbooks or the FAA Form 337, you are stating that the
installation has been performed in accordance with the current FARs and with the
steps and procedures outlined herein.
In Canada, all installations must be performed in accordance with the Engineering
and Inspection Manual Part II, Chapter III, Section 3.12.
Remember: Your Professional installation may save someone’s life.
2.2.1 ELT MAIN UNIT LOCATION AND INSTALLATION
2.2.1.1 ELT LOCATION DETERMINATION:
Many of the original ELT installations are inadequate as far as unit location and
surface rigidity are concerned. Just because the “old” ELT was located in a particular
position doesn’t mean the “new” ELT should be located there as well.
The tail section of an airplane is least likely to be damaged during a crash and
therefore, it provides a good mounting environment for the ELT unit. Refer to Figure
1 for Direction Determination for Fixed Wing Aircraft and Helicopter, respectively.
Accessibility of the unit is an important factor in the location of the ELT. Mount the
unit as far aft as practical but where it can be easily retrieved for maintenance.
The mounting surface must be extremely rigid; therefore, mounting the ELT directly
to the aircraft skin is unacceptable.
Mounting an ELT directly to the aircraft skin induces “crash hiding” vibration and
provides a very poor structural mounting surface. The mounting location must be
able to support 100 pounds of force in any direction with no appreciable distortion in
the structure. It must also be able to withstand a 350-pound force in any direction
without tearing or breaking the aircraft structure.
Please refer to FAA AC 43.13 for guideline.
27
Following are the FAA guidelines for mounting a TSO-C91a ELT, per RTCA
DO-183 paragraph 3.1.8:
1. “The ELT shall be mounted to primary aircraft load carrying structures such as
trusses bullheads, longerons, spars, or floor beams.”
2. “The mounts shall have a maximum static local deflection no greater than 2.5
mm (0.1 in) when a force of 451 Newtons (100lbs) is applied to the mount in the most
flexible direction. Deflection measurements shall be made with reference to another
part of the airframe not less than 0.3 meters (3 feet) from the mounting location.”
In addition, RTCA Document number DO-182 recommends that “all ELT system
components which must survive a crash intact, should be attached to the airframe in
such a manner that the attachment system can support a 100g load…in the plus and
minus directions of the three principal axes of the aircraft.”
The ELT must be mounted with the arrow which is printed on the battery case
pointing in the direction of flight. The ELT should be mounted with its longitudinal
axis aligned within 10 degrees of the longitudinal axis of the aircraft fuselage. Avoid
mounting the ELT near sources of strong EMI/RFI radiation. (See Fig. 1)
If this is a new installation or if the current installation is unacceptable, find a location
per the following:
RTCA suggests the aft section of the fuselage. Statistically, this is the least likely
section of the aircraft to receive damage in a crash. It is also near the antenna
connection, minimizing cable length between the transmitter and antenna. Maintain
access for maintenance. If possible, avoid locating the ELT where it will be subjected
to chemical fluids such as deicing compounds, cleaning fluids, etc. Over time, these
may attack the plastic and metal components.
The mounting location must conform to the requirements of RTCA DO-204 and AC
43.13-2B. DO-204 Sec 3.1.8 states:
"The ELT shall be mounted to primary aircraft load carrying structures such as
trusses, bulkheads, longerons, spars, or floor beams (not aircraft skin). The mounts
shall have a maximum static local deflection no greater than 2.5 mm (0.1 in.) when a
force of 450 Newton's (100 lbs) is applied to the mount in the most flexible direction.
Deflection measurements shall be made with reference to another part of the airframe
not less than 0.3 meters (1 foot) nor more than 1.0 m (three feet) from the mounting
location."
Separate mounting-hole patterns are provided so that, if the AK-451 is replacing an
existing ELT listed below, the original mounting holes can be used. Remove the old
ELT holder or tray and install the AK-451 mounting tray in its place. Stainless steel
hardware is recommended. Use hardware conforming to an accepted standard such as
AN or Mil-Spec.

29
Helicopter Installations:
The AK-451-(14)(15)(17)(18) may be mounted so that the arrow aligns with the
longitudinal axis of the aircraft. If necessary, the ELT may be tilted Nose down up to
10 degrees, (see Figure 1.1). The ELT mount may be rotated about the aircraft center
axis, i.e., the ELT can be mounted on the floor, walls or over head, so long as it
‘points’ to the front of the aircraft.
Also, refer to aircraft manufacturer’s data (Type Approval or STC information)
and/or national regulations regarding installation on helicopters.
Figure 1.1: Direction Determination for Helicopter
2.2.1.2 MOUNTING TRAY AND CLAMP HOLDER INSTALLATION:
After selecting a suitable location meeting all of the above requirement, drill, mount,
must install the ELT MountingTray as shown in Figures2.1.2and 3.Mark the4 holes in
trapezoidal locations needed for the tray using the tray as a guide. Be sure the tray
aligns within 10 degrees of the longitudinal axis of the aircraft (and in direction of
flight). The mounting Tray may be mounted on the Horizontal plane or Side wall, or
Overhead, as long as the FORWARD Arrow direction shown on the ELT is adhered.
Note: The purpose of 4 holes in trapezoidal configuration is to assure that both the
ELT and mounting tray will be placed in the correct direction (with the arrow
FORWARD direction marking on the ELT must be adhered.) Therefore, make
sure the direction of the 4 mounting holes in trapezoidal configuration is correct.
If a reinforcement (Doubler) plate is needed to meet the rigidity requirements of
paragraph 2.2.1.1, fabricate one using the tray as a guide.
