AvionTEq

AvionTEq is a distributor with its own inventory of aviation test equipment and aircraft tools. The company works with maintenance shops, operators, and manufacturers around the world. Its business revolves around the testing, calibration, and repair of avionics equipment.

The team has nearly two decades of experience in aviation. AvionTEq is part of an FAA Part 145-certified repair station, the U.S. regulation governing facilities authorized to repair aircraft components. The company is a member of PAMA, NBAA, HAI, the Aircraft Electronics Association, the Aeronautical Repair Station Association, and EBAA.

What kinds of devices can you find on the shelves?

The catalog starts with pitot-static testers, which check the instruments that measure airspeed and altitude. Next are multifunctional flightline test sets, portable data loggers, and testers for transponders and ADS-B. There are also NAV/COMM testers, data bus testers, radar testers, altimeter testers, fuel quantity testers, and loop resistance (LRT) testers.

The list continues with laser cable markers, battery chargers and analyzers, industrial endoscopes (borescopes), and tilt and rotate tables. The brands include well-known names in the field, such as Viavi/Aeroflex, Barfield, Laversab, Teledyne Controls, Nav-Aids, and Flight Data Systems. The latest release is the ULBTEq UTS100, a tester for the underwater locator beacon (ULB) mounted on flight recorders. The beacon is what "beeps" underwater so the black box can be found.

Should you buy, rent, or lease?

Here, the website makes a clear distinction. Renting—whether short- or long-term—is intended for emergencies, one-off projects, and research and development. It's also a kind of test drive, because you can try out the device before buying it. The rent-to-own option converts part of the rent into a down payment on the purchase.

Leasing is tailored to your budget, needs, and project duration, with full financing or the option to purchase at the end. Applications are submitted through ACG Capital, and a downloadable calculator provides an estimate of the monthly payment. The equipment—whether new or refurbished—arrives tested, calibrated, and ready for use.

There's also the reverse process. AvionTEq purchases test equipment from surplus inventory and offers credit toward the purchase of new equipment in exchange for your old units. There is a separate form for this, "Offer to Sell."

When a device needs inspection

The company repairs, maintains, and calibrates bench and ramp equipment—that is, devices used in the workshop and those used next to the aircraft on the ramp. It also works with older models that are no longer in production or are no longer supported by the manufacturer. Calibration includes functional testing, adjustments where necessary, and verification against the manufacturer's specifications.

Each calibration comes with a NIST-traceable certificate—NIST being the U.S. National Institute of Standards and Technology—and detailed test data is provided upon request. The calibration record is similar to a car's service log, as it shows that the instrument measured correctly when it was used. The website notes that, in some cases, maintaining this record is also a regulatory requirement.

For those purchasing new or refurbished equipment, there is the TEqSupport program. The package includes a one-year warranty, one year of technical support, and one recalibration per year. While the device is in service, the customer receives a loaner unit, so work in the hangar doesn't come to a standstill.

Digital Tools and Flight Data

TEqSupport also provides access to MyTEq, the company's online tool for managing test equipment. The AvvSight platform, presented at the AEA convention in New Orleans, uses augmented and virtual reality for remote maintenance, inspection, and training. The technician and the expert communicate via audio-video calls, draw on the same documents, and can open manuals, technical data sheets, or calibration certificates.

In my opinion, AvvSight is the most remarkable part of the offering, as it brings the expert right next to the aircraft without needing a plane ticket. AvionTEq also has an exclusive, multi-year agreement with Flight Data Systems for HHMPI interfaces and for reading data from voice and flight data recorders (CVR/FDR). The offering also includes support for 25-hour voice recorders, plus courses in the eTraining section.

Who works with them?

The client list includes BAE Systems, Boeing, Lockheed Martin, Raytheon, Bombardier, Airbus Helicopters, Delta, Mesa Airlines, Rockwell Collins, and NASA. Customers range from small workshops to large maintenance, repair, and overhaul (MRO) centers, manufacturers, and airlines. Flight Data Systems honored the company as a Premier Partner at NBAA-BACE 2024, and FDS received a second award at MRO Americas 2026.

As a reviewer, I noticed that the testimonials particularly highlight the speed of responses and the updates received during repairs. The website features a page dedicated to its commitment to quality and a customer satisfaction survey. The interface is available in multiple languages, including English, Chinese, Japanese, and Spanish.

How do you request a quote?

Prices for many products are displayed after logging in, and orders are placed through your account. For specific products, there is a request for quote (RFQ) feature and a shopping cart from which you can quickly submit a request. The contact page includes a form for email and phone numbers, but no business hours are listed. The website also features a blog, a careers section, and monthly offers.
