Avionics Test Equipment: New or Used—What’s Best for MROs?

For Maintenance, Repair, and Overhaul (MRO) facilities, investing in avionics test equipment is a strategic decision—not just an operational one. These tools directly influence aircraft safety, airspace compliance, troubleshooting accuracy, and shop profitability. But when it comes to purchasing, the question remains the same for many MRO leaders and technicians:

Is it smarter to buy new, or does used equipment deliver better value?

The answer isn’t universal. It depends on budget, test frequency, regulatory needs, and long-term business goals. Let’s break down what truly makes the most sense.

The Case for Buying New

New avionics test equipment offers clear advantages:

• Longer service life and lower risk of early failures

• Latest software and compliance standards pre-installed

• Full manufacturer warranty, technical support, and firmware updates

• Modern interfaces that shorten training time and improve technician adoption

• Greater reliability during audits and certification testing

For high-utilization shops, airlines with strict uptime targets, and facilities aiming to standardize their test processes across teams, new equipment can be a long-term asset that reduces operational disruptions.

However, new units often come with a higher upfront cost, which can stretch budgets—especially for small to mid-sized MROs or seasonal workload spikes.

The Case for Buying Used

Used or refurbished avionics test equipment appeals to many MROs for one major reason:

Cost efficiency.

Additional benefits include:

• Lower capital expense for the same core test capabilities

• Faster procurement when inventory is already available

• Ideal for short-term projects, rental conversion, or backup units

• Practical for shops testing specific systems, not full avionics suites

• Some refurbished units include fresh calibration and accessories, bridging the gap between price and performance

But there are risks to consider:

• Older batteries, displays, switches, or modules may fail sooner

• Limited or no warranty depending on source

• Possible outdated software or compliance configurations

• Higher likelihood of repeat repairs if the unit has aged components

• Unknown handling history if not purchased from a trusted aviation supplier

For these reasons, used equipment makes the most business sense only when it is refurbished, calibrated, and validated by a reputable provider—not simply purchased “as-is” from the secondary market.

So, What Makes the Most Business Sense?

Here’s a practical rule of thumb followed by many MRO decision-makers:
