Niacc-Avitech Technologies Drives Growth with ADMET Investment
Niacc-Avitech Technologies is an aircraft component overhaul and manufacturing facility in Fresno, CA. The company repairs and overhauls starters, generators, fuel assemblies, cable harnesses, electronics, brake and hydraulic components, and other aircraft appliances and components. The company also has a build-to-print division that supplies major customers with electrical rotors, starters, and wire harnesses. Niacc recently received a customer request to add overhaul and servicing capabilities for landing gear shock absorbers to its portfolio of services. The technical specifications meant that Niacc would need new test equipment. It was difficult for Rayan Kabeer, Niacc’s head of engineering and product development, to find a test machine that would apply the right amount of load, some 49,000 pounds. The offerings from other companies were either too big or too small. They could have custom built a machine, but the time and money associated with that were too great.
After a rigorous diagnostic assessment of Niacc’s needs, ADMET’s Account Director recommended ADMET’s ExPress/eXpert 1600 Universal Testing Machine equipped with the MTESTQuattro materials testing system. Specifically, the configuration that worked best was the ExPress 300 kN (60,000 lbf) dual-column servo-hydraulic materials testing machine equipped with the MTESTQuattro materials testing system. This is a Microsoft Windows-based software product that controls tests, collects and reports data, and offers sophisticated tabular and graphical representations of test results for analysis and comparison. The machine arrived within six weeks of the initial conversation.
Mr. Kabeer is especially pleased with the MTESTQuattro materials testing system. “The best thing about ADMET is that, with their software, we can control the test pretty much hands-off,” he said. MTESTQuattro also graphically plots the test results and highlights any test parameters that are out of tolerance, making it easy to spot failures. The results are saved in a database that, by regulation, is kept for two years after the part has been shipped. Thanks to the investment in ADMET technology, Niacc was able to respond to its customer’s request for a new line of testing and is now providing the service to other customers that operate the same aircraft. Additionally, there are other similar aircraft that use the same type of shock absorber. The ExPress machine Niacc purchased from ADMET can be used to test these and other larger shock absorber assemblies, further extending the market and driving new business.

ADMET Delivers an Innovative Solution to Leading Corporate Jet Manufacturer
A leading U.S. based manufacturer of private and corporate jets was called upon to expand maintenance capabilities to include the testing of shock strut assemblies, shock absorbers, and actuators for aircraft landing gear. Both main and nose gear were to be accommodated by a single system. To reach the largest potential market of business aircraft owners, a flexible, high capacity testing system was needed. Also, because each aircraft maker has their own maintenance testing requirements and they all differ in significant aspects, an adaptable testing system was required. This new capability required precision transducers, complex control, and the ability to adapt for different sizes and types of test assemblies. Critical to the test program was the ability to measure the rotational steering position of the loaded landing gear.
The prospect submitted their specifications to a select set of uniquely qualified suppliers for comments. One test required applying a compressive uniaxial load, then twisting the steering knuckle and measuring torque and angle of rotation. ADMET analyzed the engineering data and responded to the opportunity with a unique solution. The solution was based on an inverted version of their rugged eXpert 1600 series servo hydraulic universal testing system and a rotating compression platen instrumented to measure angle. The jet manufacturers’ customers demanded timely service so keeping test system downtime to a minimum was important. Thus, a testing system constructed with multiple domestic part sources was also a requirement. ADMET’s eXpert 1600 series testers, made in the USA using off the shelf American made parts, satisfied this requirement. In the client’s words “Once we reviewed each of the suppliers, we decided the only choice was ADMET.” Two months later, the system was operational and training completed.
The eXpert 1600 series servo hydraulic universal testing system equipped with ADMET’s MTESTQuattro Materials Testing System has performed beyond expectations and without a single instance of service. The customer found the test system incredibly easy to use, and configurable to perform a variety of tests. When the customer is called upon to create a new method of testing, MTESTQuattro allows them to implement it in minutes. Since ADMET software allows installation on multiple computers, the client designs new testing procedures at their desks and downloads them to the testing system in the hangar. This saves a considerable amount of time and reduces errors. When loading and unloading the landing gear assemblies, they use a fork lift or winch so “bumping” into the testing machine is a common occurrence. Subsequent calibration verifications, done every three months, confirm that the force, torque and alignment have exhibited no ill effects. As stated in a recent follow up call with the client: “We have performed hundreds of tests, many consisting of thousands of cycles each, and the hundreds of hours of faultless operation have served to confirm our decision to purchase from ADMET, Inc. We consider ourselves fortunate to be an ADMET customer and their application and technical support continues to be responsive, friendly and professional.”
