What we got
This old photo of the Cessna F 172G, built in 1966, shows its original condition from 2012.
In the first instance, a Trig TY96 COM and a Becker BXP6403 Mode-S transponder were installed as part of the 8.33 frequency obligation. With this equipment, the aircraft was used by the Aero-Club Osnabrück for guest and sightseeing flights for many years.
New owner – new avionics
During a short stay at the maintenance station to check the airworthiness, an initial revision of the panel was undertaken. The panel covers and glareshield were painted black and the avionics were repositioned. During the avionic check, a defect in the installed Becker Mode-S transponder was discovered. A repair was not an option due to the costs. A Trig TT31 transponder was quickly retrofitted because it was replaceable 'plug and play'.
The preliminary result is a tidy panel
Further renovation and modernization of the panel began in the winter.
The old altitude and attitude gyros should be replaced with modern Garmin G5 instruments. Since the existing instruments did not have a standard 3 1/8" cutout, the left panel had to be completely redesigned. After internal consultation, the decision was made for the more complex but much nicer “flushmount” version for the Garmin Dual G5 EFIS package. The plastic cover on the left panel, which was broken several times, gave way to laser cutting. The result is impressive on the bench.
The Trig TY96 COM and the Trig TT31 Mode-S transponder were adopted from the previously existing avionics. The remaining devices were completely removed.
The new avionics now includes the following components:
1x Bendix/King KMA 26 (Audiopanel with Intercom)
1x Garmin GNS530 (COM/NAV/GPS/FMS)
1x Trig TY96 (COM)
1x Trig TT31 (Transponder Mode-S)
1x Garmin G5 (ADI#1)
1x Garmin G5 (HSI)
1x Garmin GAD29B (Data-Interface)
1x Garmin GMU11 (Magnetometer)
1x Uavionix AC30C (ADI#2)
1x Air Avionics AT1 (Traffic Avoidance System)
1x Kannad AF Integra (406 MHz ELT)
At the same time, all old fuses and cables were removed and the old, unshielded intercom cables were replaced. The existing antenna cables were also replaced with double-shielded RG400 cables.
The Pitot-Static lines, some of which were over 50 years old and had become brittle, were removed or replaced.
The end result makes you want to fly!
The next step is to replace the right plastic panel with a laser-cut panel to complete the picture … to be continued …
Aeroteam wishes "many happy landings“.
