BEFORE

Worldwide Aircraft Services Inc.

Worldwide Aircraft Services' goal was to improve the
reliability and situational awareness for the customer.

Worldwide-aircraft.com * Springfield, Mo.
Number of employees: 40
Installers/technicians involved
with the project:
*
Alan Fox (avionics manager)
*
Tim Kallenberger (avionics
installer)
Aircraft type:
Fairchild Metro III/C-26A
What was the objective
of the project?
Improve reliability and situational
awareness by replacing the
existing EFS-10 EFIS/KNS-660
FMS with a modern cockpit
including Universal EFI-890R
System and Dual UNS-1Fw FMS,
Universal TAWS, Dual Litef LCR100 AHRS, and Honeywell RDR2000 weather radar.

What date was the project
started?
July 2015
What date was the project
completed?
May 2016
What makes this
installation unique?
This was the first installation
of the Universal EFI-890R
equipment in a Fairchild Metro/
Merlin series aircraft.
Did you encounter any
problems while working on
the project?
The biggest problem we had
was with the first type of AHRS
we installed. When we began
test flights, the autopilot was

AFTER

extremely shaky and jittery in
the roll mode, and somewhat in
the pitch mode. After extensive
troubleshooting, we determined the
root cause was the AHRS roll and
pitch outputs; they were just not
smooth enough.
How did you resolve
these problems?
Ultimately, the manufacturer of the
AHRS acknowledged the problem but
was unable to resolve it. At that point,
we had to abandon that AHRS and
installed the Litef LCR-100; it solved
the problems and worked well.
Did you learn anything
from this project?
We always learn things from projects,
but on this project the plane came
from many years operating out of
a Caribbean island. We learned a
lot about how the harsh, salt water
environment attacks the avionics on
these planes. The other big lesson for
us was how excellent the customer
support is from Universal Avionics.
The company went above and beyond
to make sure we had all the support
needed to make the project a success.
What was the
customer's response?
They loved it. The reliability
problems they had with the original
EFIS system are gone, and the new
system works and looks good. q

This project was the first installation of the Universal EFI-890R equipment in a
Fairchild Metro/Merlin series aircraft.
