To assure customers that the parts we provide will perform as promised, both functional and dimensional analyses are critical to our design process. All parts are analyzed as to how they function, how they might fail, and what impact that failure would have on the operation of the engine or aircraft – including computations and tests that evaluate every potential risk for a part. Then, using sophisticated techniques for dimensional and tolerance analysis, we design to assure the proper form, fit, and function of the part into the assembly. To assist us in the design process, our engineering capabilities include:
- 3D computer aided design and drafting
- Finite element analysis to analyze part stress levels
- Failure mode and effects analysis
- Statistical analysis
- Stack up and tolerance analysis
Our partnership with some of the industry’s most well-known Materials Laboratories provide us with the ability to identify both metallic and non-metallic materials. Lab accreditations include NADCAP, ISO 9001, ANSI/ASQC Q9001-94, and the Fastener Quality Act.
Metallic materials are analyzed to check chemical, mechanical, and metallurgical properties of the candidate part to match material, hardness, and strength. Chemical analysis is done at the element level to determine the original OEM alloy or alloy classification – critical when dealing with parts from foreign manufacturers where the material used must be cross-referenced to the proper US alloy.
Non-metallic material analysis may consist of FTIR to identify the material spectrum and thus chemical properties, DSC to investigate the response to heating, ASTM analysis of filler content, hardness (durometer) check and SEM.

The driving force behind our approach to quality control is simple – Customer Focus. We strive to provide our customers with the highest quality, airworthy parts, every single time they order. Quality is not limited to requirement compliance, it also includes value and customer perception. We are an FAA Production Approval Holder (PAH No. PQ2685CE). Our Quality Management System uses a process approach to obtain desired results and seek opportunities for continuous improvement. Other key components of our quality program include:
- Part Conformity – To verify that the prototype or production parts conform to the design, we use a range of inspection equipment such as coordinate measuring machines, digital micrometers, optical comparators, profilometers, and electronic height stands.
- Inspection – The FAA delegates our DAR (Designated Airworthiness Representative) or DMIR (Designated Manufacturing Inspection Representatives) to perform conformity and airworthiness inspections. We have DAR and DMIRs on site. This allows us to be far more responsive in both the development and shipment of our products.
- Traceability – All ACS parts are traceable through a unique identifier to the applicable raw materials, manufacturing lots, machining, special processing, and inspection data.
Partnering with a core group of world-class aerospace suppliers, the manufacturing side of our business includes complete milling and turning capabilities including CNC multi-axis (3-, 4-, and 5-axis) machining. Using these industry partners, we’re able to conduct rigorous testing and manufacturing of complex assemblies.
State-of-the-art capabilities also allow us to take advantage of the latest manufacturing methods to reprocess older parts for closer tolerances, less part-to-part variation, better surface finishes, shorter manufacturing lead times, and reduced costs.
Other manufacturing capabilities include:
- Grinding and forming to achieve tolerances in the .0001 inch range for greater part to part uniformity and better surface finishes.
- JIG grinding of elliptical and other non-round parts for tight tolerances, part uniformity, and superior surface finish.
- Super finishing for surface finish of less than 4 micro-inches (rms) to reduce friction and wear.
- Heat treating to achieve proper hardness levels, including nitriding and carburizing
- Coating and plating, including anodize and conversion coat of aluminum, hard chrome, cadmium and nickel plating of steel, molecular dry film, primer, paint, and all common aerospace finishes.
- Injection molding, trimming and cryogenic deflashing of elastomeric parts.
