8 Instructions for Continued Airworthiness
This section provides Instructions for Continued Airworthiness of the
tailBeaconX system as installed under STC _____________ and satisfies
the requirements for continued airworthiness as defined by 14 CFR Part
23.1529 and Part 23 Appendix A.
8.1 Airworthiness Limitations
The Airworthiness Limitations section is FAA-approved and specifies
maintenance required under 14 CFR Part 43.16 and 14 CFR Part 91.403 of
the Federal Aviation Regulations unless an alternative program has been
FAA-approved.
There are no new or additional airworthiness limitations associated with this
equipment and/or installation.
8.2 Servicing Information

STC User and Installation Manual Section 7 for equipment removal and
installation. No component-level overhaul is required.
8.2.1 On-Condition Servicing
On Condition replacement and/or servicing may be required when
conditions, symptoms, and/or servicing should take place only after the
system is troubleshot based on guidance provided in this manual and per
common avionics maintenance practices.
8.2.2 Special Tools
The following tools are needed to perform maintenance tasks.
•Ground power source (capable of supplying sufficient power to the
aircraft systems and avionics)
•iOS or Android Mobile Device with “uAvionix skyBeacon Installer”
App
•Dark glasses for viewing LEDs directly at close range
•Transponder ramp test set

Note 1 - Mode S transponders respond to a minimal set of transponder
interrogations while on-ground. tailBeaconX can be placed in an airborne
state for test purposes by entering “Ground Test Mode” using the installer
application, or by using certain compatible control heads. During
transponder testing, ensure static pressure test set is NOT connected. For
more details see tailBeaconX TSO User and Installation Guide (UAV-
1004270-001) Section 9.5.
Note 2 - tailBeaconX must be in Standby mode during 91.411 testing to
ensure no false position report broadcasts during pressure altitude system
testing.
8.4 Visual Inspection
Perform a visual inspection as detailed in this section. Check tailBeaconX
system components for damage or other defects and replace as required.
Inspection may require the temporary removal of a unit to gain access to
connectors. Follow guidance in the tailBeaconX TSO User and Installation
Guide for equipment removal and replacement. Refer to model specific
Aircraft Maintenance Manual for instructions on removing access panels or
covers, as required.
8.4.1 tailBeaconX Visual Inspection
•Inspect the tailBeaconX unit and verify it is securely mounted.
•Inspect the unit fasteners and verify they are properly torqued and
show no wear or damage. Additionally –

UAV-1003600-001 Page 14 of 17
Rev B
oVerify unit support structure is in good condition and its integrity
is not compromised.
oInspect for corrosion and treat as required.
•Inspect the condition of the wiring.
oVerify that all wiring and cables are securely fastened.
oVerify that the harness shows no signs of cracking, chafing,
abrasion, melting, or any other form of damage.
oInspect the tailBeaconX connectors for corrosion, evidence of
moisture, or other defects.
8.4.2 Position Light Visual Inspection
The rear position light is designed with 2 white LEDs. If any one LED fails,
the unit must be repaired or replaced.
Note: Use dark glasses or cover the device to ensure eye safety during
LED inspection.
8.5 Post Lightning Strike Inspection
Inspection of the tailBeaconX unit must be performed following a suspected
or actual lightning strike. The tailBeaconX and nearby aircraft structure and
cabling must be inspected to verify no damage has occurred where
lightning may have attached. A tailBeaconX with visible signs of damage
should be replaced. Grounding hardware and nearby aircraft structure
supporting tailBeaconX installation must be inspected for damage. Repair
any damaged components.
9 Post-Installation Test Procedures
Procedures that must be completed when the tailBeaconX is removed and
re-installed or replaced with a new unit are detailed in this section.
Refer to tailBeaconX TSO User and Installation Guide Section 9.4 and 9.5
for Post-Installation Checks.
If no other service is to be performed, continue to the Return to Service
Procedure in Section 11.
