SECTION I

GENERAL INFORMATION

1.1 SCOPE

This manual contains information necessary for the Operations and Instructions for
Continued Airworthiness (ICA) of the model AK-451, Emergency Locator
Transmitter, manufactured by Ameri-King Corporation, California, U.S.A.

1.2 OVERVIEW

. The Ameri-King AK-451-( ) Series is a FAA TSO C-126/91a approved, EASA
ETSO approved, 406 MHz ELT Emergency Locator Transmitter, Types (AF)
Automatic Fixed, (AP) Automatic Portable, (S) Survival. It may transmit aircraft
GPS/NAV position data, immediately and accurately, on triple (406 Satellite /243
Military /121.5 Civilian) MHz frequencies.

1.2.1 Application and Equipment Limitation.

This manual constitutes FAA approved data as described in AC 43.9-1E, paragraph
(h)(2) and AC 43-201, chapter 2, paragraph 201(a)(6) for major alterations. Not all
installations are “major”; consult your local FAA ACO for clarification.

In Canada, Installation of an ELT in an aeronautical product is carried out under a
Supplemental Type Certificate (STC). This is a separate regulatory requirement and
should therefore be in a separate document manual for the Operations and Instructions
for Continued Airworthiness (ICA).

The conditions and tests required for TSO approval of this article are minimum
performance standards. It is the responsibility of those desiring to install this
article on a specific type or class of aircraft to determine that the aircraft
installation conditions are within the TSO standards. TSO articles must have
separate approval for installation in an aircraft. The article may be installed
only if further evaluation by the applicant documents an acceptable installation
and it is approved by the FAA Administrator. The article may be installed only
if performed under 14 CFR parts 43 or the applicable airworthiness
requirement. For installations outside of the US, contact your local civil aviation
authority for guidance (Ref. TSO-C126 paragraph D).

Lithium battery safety concerns include the possibility of fire, venting violently,
and venting of toxic gases (Ref. TSO-C126 par agraph 5.a.(2)).

The AK-451 ELT described in this manual was designed, tested and certified as a
complete system including the following components:

7

Note:

Only Ameri-King approved system components may be used for a TSO approved

system.

1.2.2 Certification:

The AK-451 has been certified to the following:

CFR § 2.902, the ELT is tested per “Verification” method.

Note:

The AK-451 is certified to meet the requirements of FAA TSO-C126, TSO-C91a and
EASA ETSO-2C126 per EUROCAE ED-62. For use outside the US or EASA
member states, contact your local civil aviation authority for ELT requirements.

Note:

There is no electronic connection between TCAS or Mode S systems and the ELT,
only the ID number is common. The ELT may accept aircraft GPS/NAV Lat/Long
position data, then transmits the position data on the 406 MHz digital long messages..

1.4 BATTERY REPLACEMENT INSTRUCTIONS

p

1.4.1 ELT MAIN UNIT BATTERY REPLACEMENT INSTRUCTIONS

All batteries are strongly advised to be serviced by Ameri-King or its authorized

service centers. End users may return the entire ELT for replacing the batteries

ost functional tests.

and

The Ameri-King Corp. Model AK-451 ELT is designed to use only with Ameri-King
lithium battery packages which have been tested per TSO-C126, TSO-C91a
requirements.

The use of any other battery will void all warranties of the ELT by Ameri-King
Corp. The ELT does not meet the requirements of TSO-C126, and TSO-C91a or
FAR 91.52 if used with any other type of battery. Using any other battery is not
allowed (forbidden).

The Ameri-King Battery Pack has a 10 years shelf life and 5 years useful life. It will
last for 78 hours at -20 deg C, at end of 5 years battery life.
FAR 91.52 (d) (i) requires that ELT batteries be replaced when the transmitter has
been in use for more than one cumulative hour.

The label sticker for expiration date of the batteries must be affixed on the
outside of the ELT battery case and recorded in the aircraft logs.

The owner or operator may perform Battery replacement provided that the
accessibility, removal and reinstallation of the ELT can be considered “simple” as
prescribed in Advisory Circular 91-44A, Paragraph 8.a (See Appendix B).

The following is a step-by-step instruction for replacing ELT Battery Pack P/N
4500010-( ) Series:

13

1. Using the 3/32” Hex Driver supplied with the ELT, remove the 4 retaining

screws and split lock washers that attach the battery case to the ELT Transmitter
Assembly (See Figure15).

2. Insure both battery connectors are locked-in properly by its tab.
Verify the battery pack voltage is 13 +/- 0.5 VDC
Ensure that the gasket is in place (See Figure 4).

3. Place the Transmitter Assembly face down on a bench. Press down on the
battery case to compress the battery contact springs. Replace the four battery retaining
screws and lock washers and evenly tighten until the battery case is pulled flat against
the Transmitter Assembly.

4. Remove any existing battery replacement date labels from the battery case and
install the new label you prepared in step 3 above in a readily visible location on the
ELT.

5. After battery replacement, a transmitter function test must be performed as
described in section 2.3 of this manual.
