About Testek

With proven experience across baseline platforms and complex programs, Testek supports the test capability OEMs and MROs need for troubleshooting, validation, and certification.

Test Expertise for Reliable Results

Generators-3258-ana-drive-base--1

Testek Solutions designs, delivers, and supports turnkey test capability with upgradeable aerospace test stands across aircraft systems and use cases. We guide OEMs and MROs in building, expanding, and modernizing test infrastructure. Our test stands enable reliable test results and the validation documentation needed for critical decisions, from troubleshooting to certification. With proven experience across baseline platforms and complex programs, we support key aircraft systems, including hydraulic, power generation, fuel, lube, actuator, pneumatic, and automated test equipment.

We simplify decisions early through responsive collaboration during the scoping process, leaning on engineering guidance to define what is technically acceptable and surface downstream requirements before they become surprises. Testek’s design philosophy makes test system ownership easier by prioritizing durability, maintainability, and room for expansion. That same approach also optimizes total cost of ownership as capability and capacity needs change over time. Our service, support, and training come from in-house experts with design and commissioning experience, resulting in continuity throughout lifecycle sustainment.

I would like to express deep appreciation to the sincere efforts of [your team]. They were excellent and have finished their job successfully. By the timely setting up of the test stand, we could go through to process to get the repair certificate of those planned units within this year. This time was a good opportunity to enhance the relationship between KAL and Testek.”

Testek engineers and technicians are very knowledgeable. It is truly a pleasure working with a company that understands how important it is to have the equipment up and running and that is willing to jump through hoops to make things happen. This test stand at Delta clearly demonstrates Testek’s superior technical design and performance. Once again, Testek has lived up to their excellent reputation for test equipment and customer satisfaction.”

Testek is a long term supplier for Parker and we are happy with the quality of the test equipment and the support provided by the Testek team. I would recommend Testek fuel nozzle equipment for any applications that may be used to test Parker manufactured fuel nozzles.”

I wanted to thank you and your team for your efforts on the test stand project. The machine is truly an engineering marvel, by far the most complicated mechanical type test stand that I’ve been involved with since I began working in the aerospace business. I know that you faced many technical, political, and programmatic hurdles on this program and I appreciate how Testek has remained patient and persevered through all of the tribulations.”

“[Your engineer’s] professionalism, courtesy, and reasonable approach to offering solutions to issues as they arose were a very refreshing experience. Without his willingness to support the program to meet customer expectations were, without doubt, the difference between failure and success. Thank you!
