Location: Mansfield, Massachusetts
Number of employees: 10

David Fetherston (company founder;
Steven Ponder (avionics technician)
Type of Aircraft:
Socata TBM 850
What was the objective
of the project?
The objective was to take the original
panel equipped with the Garmin
GNS 530W and replace it with
Avidyne's slide-in GPS/NAV/COMM
replacements, the IFD540.
When did the project begin?
The STC for Avidyne's newest GPS/
NAV/COMM panel-mount avionics,
the IFD540, came through on
Thursday, July 24, 2014. Avidyne's
owner and chief executive officer,
Dan Schwinn, brought his TBM 850
to the NexAir Avionics shop Friday,
July 25, 2014, for the install.
When was it completed?
The TMB 850 rolled onto our ramp
and, as advertised, the install took
five minutes; however, we delayed
the customer for a photo shoot for
our own marketing purposes. The
work order, log book entry and
invoicing will take longer. We'll
schedule those installs as an hour
beginning to end.
What makes this project unique?
Sheer install time is what makes
this installation unique. If the GNS
530W's rack and connectors are left in
place and a WAAS antenna has been
previously installed, the job simply
requires a technician to remove the
GNS 530W and slide the IFD540
into the existing rack, secure, and
complete the configuration.
Did you encounter
No, the new avionics were delivered
before the aircraft arrived, and the
install went smoothly.
Did you learn anything
from this project?
When you hear "slide-in replacement,"
there always is a question in the back
of your mind asking if it truly is a
slide-in-replacement. The answer is
yes, which from an avionics shop's
perspective, allows us to accurately
plan our job schedule.
What was the customer's
The aircraft owner had a very
satisfying flight all the way to
AirVenture 2014 in Oshkosh,
The 2007 Socata TBM 850 left NexAir Avionics with its previously installed MFD, Audio Panel and Transponder, and two newly STC'd Avidyne IFD540 GPS/NAV/COMMs.
