Overview
Aero Charter publishes a Garmin avionics service page for its operation at Spirit of St. Louis Airport (KSUS) in Chesterfield, Missouri. The page describes avionics installation, upgrades, troubleshooting, repairs, software updates, and system configuration. It also says the company operates an FAA Part 145 repair station. That credential statement is provider-reported here, not independently verified against a current FAA record.
This profile summarizes the operator's page as checked on October 4, 2026. It does not assess the quality of the work, confirm a current appointment opening, or determine whether a task is within the facility's approved ratings.
Published avionics work
The operator describes Garmin avionics support that ranges from diagnostics and corrective troubleshooting to software updates and complete system repairs. Its page also lists new installations and upgrades for Garmin equipment. Examples named on that page include GTN Xi navigators, G500 TXi and G600 TXi displays, GFC 500 and GFC 600 autopilots, GI 275 instruments, GNX 375 and GTX 345 transponders, and engine indication systems.
The page discusses the Garmin GFC 600 autopilot for Beechcraft King Air 200 aircraft. It describes features and an FAA supplemental type certificate approval for that installation. An aircraft owner should confirm model, serial number, configuration, and applicable approved data with the shop and the relevant manufacturer documentation. A product example on a provider page is not evidence that every variant is eligible.
Aero Charter outlines a project process that begins with consultation and quoting, followed by scheduling, installation, testing, sign-off, and a pilot walkthrough. It says full-panel work includes discussion of instrument and control layout with the pilot or aircraft owner. Ask what is included in the proposed scope, how changes are approved, and what records or post-installation support will be provided.
Credentials and source limits
The operator's page describes Aero Charter as an FAA-certified Part 145 repair station and its technicians as FAA-certified. Those are claims published by the provider. The listing does not carry a current FAA certificate number, rating list, or operations specifications, so it does not independently establish the facility's authorized scope.
The FAA explains that a repair-station certificate applies to defined ratings and approved functions. Before scheduling work that depends on a certificate or rating, check the current facility record and ask the provider which approval covers the specific article or task. Start with the FAA's facility dashboard, then confirm the details with the provider.
Costs and scheduling
The source page provides a quote request path but no public installation rate or standard package price. Request a written estimate that identifies parts, labor, configuration work, testing, documentation, and any pilot orientation. Ask how the shop handles parts lead times, changes discovered during installation, and aircraft downtime. No turnaround time is guaranteed by this directory.
What to verify before committing
Give the shop the aircraft make, model, serial number, current avionics list, and intended changes. Ask whether the exact combination is supported, which approved installation data applies, what equipment must be removed or replaced, and how the completed system will be tested. Confirm that the quoted work covers any desired software configuration and pilot orientation.
Check current schedules directly with Aero Charter. Confirm the access and parking arrangements for presenting an aircraft at KSUS, and clarify how the facility will communicate delays or scope changes. The airport reference directory contains airport records, while the mechanic directory contains other sourced listings. Neither confirms facility availability.
