SECTION 5
MAINTENANCE
5.1 INTRODUCTION
This section contains general flight line maintenance and fault isolation procedures. Fault
isolation is intended to aid in identifying and correcting invalidities or isolating failures to a
defective assembly.
5.2 CONTINUED AIRWORTHINESS
Regular maintenance of the KTX2 is not required except as included in this section and is to be
maintained on a “Condition Monitored” basis. Condition monitoring is based upon the following:
Visual observation by the user.
All units have unlimited service life, therefore service life is defined as that point in time when
repair is no longer economical.
5.2.1 Periodic Maintenance KTX2
Perform the following at regular aircraft inspection intervals:
•
Visually inspect for signs of corrosion.
•
Visually inspect for condition of wiring, shield terminations for proper grounding, routing,
and attachment/clamping.
•
Visually inspect the unit mounting to the aircraft, verify visually that the screw heads are
in full contact with the mounting holes etc. Re-torque the screws if required.
•
It is recommended that an electrical bond check be performed between the unit and
nearby exposed portion of the aircraft metallic structure and verify that the measured
value is less than or equal to 2.5 milliohms.
•
In the event of bonding check failure, remove the unit and clean it and its mounting holes
at both the unit and the aircraft structure and reattach the unit. Re-verify the resistance
between the unit and nearby exposed portion of aircraft metallic structure, and ensure it
is less than or equal to 2.5 milliohms.
5.3 FAULT ISOLATION
Use the troubleshooting help provided in Table 5-1 during initial installations and debugging
issues that may appear during operation.
Use Table 5-1 to view observed failures or conditions and determine possible causes and
recommended corrective actions. Failures are typically observed via Failure or Warning
indications on the KTX2 screen.
If the only corrective action left is to contact TQ-Group Field Service, then Field service
personnel may request information copied from the Test and Configuration pages.
NOTE
A copy of the
KTX2 Instructions for Continued Airworthiness
should be
kept in the aircraft logbook.
