MAINTENANCE MANUAL

ARTEX ELT 1000 EMERGENCY LOCATOR TRANSMITTER - DESCRIPTION AND OPERATION

1. GeneralA. The Artex ELT 1000 Emergency Locator Transmitter (ELT) is installed in the tailcone of the airplane

to help rescue crews find the airplane in the event of a crash.

2. DescriptionA. Artex ELT 1000 Emergency Locator Transmitter System

(1) The Artex ELT 1000 ELT system includes the components that follow: ELT beacon unit, internalbattery pack, buzzer, internal G-switch, antenna, remote switch, cable assembly, and coaxialcable.

(2) The Artex ELT 1000 beacon is an automatic fixed beacon that transmits on both the 121.5 MHzand 406 MHz frequencies.

(3) The internal battery pack consists of two removable lithium D-cell type batteries. The batterypack is replaced as necessary in the field.

(4) A warning buzzer is installed in the tailcone next to the ELT unit. The buzzer gives an audiblewarning when the ELT is activated.

(5) The internal G-switch activates the ELT 1000 beacon in the event of an airplane crash. TheG-switch will trigger the ELT 1000 beacon when there is a sudden reduction in forward speed ofthe airplane. The G-switch is armed through the connection of the cable assembly to the ELTunit. In the cable assembly, a jumper cable between pins 5 and 12 on the electrical connector(PT906) closes the G-switch loop.

(6) The ELT 1000 system uses an antenna to transmit the emergency locator signal. The ELTantenna is installed on top of the tailcone skin, forward of the vertical stabilizer. The ELT antennais connected to the ELT unit inside of the tailcone with a coaxial cable.

(7) The remote switch is mounted on the right instrument panel in the cockpit. The ELT remoteswitch is a two-position rocker switch that can be set in the ARM or ON positions.

3. Operation

CAUTION: Operate the emergency locator transmitter (ELT) system only during the firstfive minutes of each hour. If you must complete the functional test at a timeother than the first five minutes of the hour, you must do the test with a directconnection to the ELT and a 30 dB attenuator. Refer to the FAA AdvisoryCircular AC-91-44A.

CAUTION: Do not operate the ELT again for 15 seconds. The ELT will transmit a 406MHz signal after the ELT is active for approximately 50 seconds. This signalis identified as a distress signal.

A. Artex ELT 1000 Normal Operation(1) During an aircraft accident, the Artex ELT 1000 will activate automatically when the G-switch

detects a sudden reduction of forward speed. The ELT will transmit a standard swept tone on121.5 MHz (emergency frequency). The 121.5 MHz signal will continue until the ELT battery hasexpired. Every 50 seconds, the 406 MHz signal transmissions will occur for 24 hours before theyautomatically stop. The 406 MHz data transmission may include Aircraft ID, GPS Coordinates,ELT Serial Number, Country Code, and COSPAS/SARSAT ID. While the ELT operates, the ELTwill receive electrical power from the ELT battery pack only. During typical operation, the ELTremote switch will be in the ARM position.

B. Artex ELT 1000 Manual Operation(1) The Artex ELT 1000 can be activated manually in the cockpit with the ELT remote switch. To

manually activate the ELT, put the ELT remote switch in the ON position. The remote switchLED will come on, the buzzer will come on with the switch in the ON position. The ELT remoteswitch can be used to do a test of the ELT system (refer to Artex ELT 1000 Emergency LocatorTransmitter - Troubleshooting).

CAUTION: Operate the emergency locator transmitter (ELT) system only during the firstfive minutes of each hour. If you must complete the functional test at a timeother than the first five minutes of the hour, you must do the test with a directconnection to the ELT and a 30 dB attenuator. Refer to the FAA AdvisoryCircular AC-91-44A.

CAUTION: Do not operate the emergency locator transmitter (ELT) for more than fiveseconds at a time. Do not operate the ELT again for 15 seconds. The ELTwill transmit a 406 MHz signal after the ELT is active for approximately 50seconds. This signal is identified as a distress signal.

A. Prepare the airplane for the Artex ELT 1000 Emergency Locator Transmitter Self-Test.(1) Put the BATTERY switch in the ON position.(2) Tune an AM radio receiver to 121.5 MHz to monitor the self-test.

B. Do the Artex ELT 1000 Emergency Locator Transmitter Self-Test.

NOTE: The self-test checks critical functions of the ELT system.

(1) Put the ELT remote switch on the right instrument panel in the ON position for approximately1 second, then return the switch to the ARMED position. Check the AM receiver for the 121.5MHz 2 cycle burst that indicates a self-test.

NOTE: If the ELT is left activated for longer than 2 seconds, no self-test will be performedon turn off.

(2) Results of the self-test are displayed by a series of flash codes where the local LED, remoteswitch LED, and buzzer activate for 1/2 second ON followed by 1/2 second OFF. Refer to thelist of codes that follows to determine the error on your ELT.(a) One flash - Shows that the system is operational and that no error conditions were found.

This message is suppressed if there are errors.(b) Four flashes - Shows an open or a short condition on the antenna output or cable. Use the

list below to isolate and repair the problem:1 Make sure the coaxial cable is connected and in good condition. Do a continuity

check of the center conductor and shield. Examine for a shorted cable.2 Examine for an intermittent connection in the coaxial cable.3 If error code persists, examine the antenna installation. This can be examined with a

VSWR meter. Examine the antenna for opens, shorts, and a resistive ground-planeconnection.

(c) Five flashes - Shows that no position data is present. Check that the navigation system isON. If the navigation system is on, check the integrity of the wiring and the connection thatgoes to the ELT. Repair wiring or connection as necessary.

(d) Six flashes - Shows that there is no G-switch loop present between pins 5 and 12. Inspectpins 5 and 12 of the ELT electrical connector for less than 1 ohm of resistance. If there ismore than 1 ohm, repair wiring as necessary.

(e) Seven flashes - Shows that battery operating time is less than 1 hour. Replace the batterypack.

Refer to Airplane Zoning - Description and Operation.B. Do an inspection of the ELT, mounting tray, antenna, and the ELT battery for condition and correct

installation.(1) Make sure that the ELT switch, found on the forward end of the ELT, is set to the ARM position.(2) Remove the ELT from the mounting tray. Refer to Artex ELT 1000 Emergency Locator

Transmitter - Maintenance Practices.

CAUTION: Do not use solvents to clean the ELT, mounting tray, or electricalcontacts. Solvents used in these areas can cause damage to theELT housing.

(3) Examine the ELT and the mounting tray for correct installation, cleanliness, cracks, or otherdamage.

(4) Examine the ELT battery for corrosion.(5) Look at the battery expiration date.

(a) Make sure that the battery life limit is not expired.(b) Make sure that the battery expiration date is shown correctly in the Maintenance Records.

NOTE: The battery manufacturer puts a mark on the battery to show the battery lifelimit. When you install a new battery in an ELT, make sure a record of theexpiration date is put in the space given on the ELT name and data plate.

(6) If you have to replace the ELT battery, refer to Artex Maintenance Manual A3-06-2749-1.(7) You must replace the ELT battery with a new battery if one or more of the conditions that follow

occur:• Use of the ELT battery in an emergency• Operation for an unknown amount of time• Use for more than one hour of cumulative time• Replacement date shown on the battery label has expired

4. Artex ELT 1000 Emergency Locator Functional Test

NOTE: If possible, do the test procedure for the emergency locator transmitter inside a metal hangarwith the doors closed to decrease the signal transmission form the ELT unit during the test.

A. Do a G-Switch Operational Test:

CAUTION: Operate the Emergency Locator Transmitter (ELT) system only duringthe first five minutes of each hour. If you must complete the functionaltest at a time other than the first five minutes of the hour, you must do thetest with a direct connection to the ELT and a 30 dB attenuator. Refer tothe FAA Advisory Circular AC-91-44A.

CAUTION: Do not operate the Emergency Locator Transmitter (ELT) for more thanfive seconds at a time. Do not operate the ELT again for 15 seconds.The ELT will transmit a 406 MHz distress signal after it is activated forapproximately 50 seconds.

(1) Make sure the BATTERY switch and the AVIONICS switches are in the OFF position.(2) Connect external electrical power to the airplane.(3) Make sure that the COM/NAV 1 and AUD/MKR circuit breakers on the circuit breaker panel are

engaged.(4) Set the BATTERY switch to the ON position.(5) Set the AVIONICS switches to the ON position.(6) Make sure that the ELT remote switch on the right panel is in the ARM position.(7) Set one of the communication units to receive a frequency of 121.5 MHz.(8) Set the communication unit to the airplane speakers at an audio level loud enough to be heard.

NOTE: The SARSAT tester is used as an example to gather test information. However,other equivalent test equipment such as the Aeroflex IFR 4000 CommunicationsTest Set is acceptable.

(9) Have another person use the SARSAT tester set to the RECV function. Refer to Figure 601.

NOTE: The SARSAT tester must be less than 15 feet from the ELT antenna and must havea line-of-sight between the ELT antenna and SARSAT tester.

NOTE: The person with the SARSAT tester must make sure that the ELT buzzer is heardduring the test.

NOTE: If it is necessary to do the transmitter test after the first five minutes of the hour,the SARSAT tester is connected directly to the ELT with a coaxial cable and a30 dB attenuator. You will not hear the sweep tone from the ELT on the airplanespeakers with the attenuator installed.

(10) Install the 30 dB attenuator between the ELT and SARSAT tester if necessary.(11) Set the ELT remote switch on the right panel to the ON position.(12) Let the ELT make three sweeps on the airplane speakers.

NOTE: This will take one second. The ELT remote switch will start to flash.

MAINTENANCE MANUAL

(13) Set the ELT remote switch back to the ARM position and monitor the LED.

NOTE: The ELT will do a self-test. The LED will stay on for one second and the ELT sweepsare not audible on the airplane speakers if the ELT operation is normal.

NOTE: The ELT does not transmit a 406 MHz test signal to the SARSAT tester until the ELTremote switch is set back to the ARM position.

(14) If the LED continues to flash, refer to Artex ELT 1000 Emergency Locator Transmitter -Troubleshooting.

(15) If the SARSAT tester did not receive a 406 MHz signal and the ELT remote switch LED does notshow a transmitter problem, do the test again.

(16) When the SARSAT tester receives a 406 MHz signal, scroll the pages on the tester and makesure of the information that follows:(a) Make sure the information shown by the SARSAT tester agrees with the placard on the

ELT.

NOTE: The information that follows must match the data on the ELT placard.

• COUNTRY Code• 15-digit Hex code ID• Aircraft identification number

(b) Make sure that the SARSAT tester shows the messages that follow:• S'TEST OK• Frequency - PASS• Homing frequency• Message format (short)

NOTE: When ownership of an aircraft is transferred within the same country, the ELT1000 should be reregistered with the applicable authority. When an aircraftwith an ELT 1000 changes tail number or country registration, the ELT willneed to have the new identification data entered. The ELT will also need to beregistered with the applicable authority.

(17) Install the bolts, tiedowns, and plastic closeout to the lower baggage area (Zone 240). Refer toAirplane Zoning - Description and Operation.
