KIHOMAC – The Air Force EWIS Experts
Treating EWIS as a System
In the late 1980s, an increasing number of aviation accidents led to raised concerns about wiring safety. Investigations performed by commercial and government entities revealed several instances of degraded electrical wiring systems. Findings from these investigations discovered several factors that led to possible wire degradation including: environment, design, maintenance, operation, time, training and others. The existing regulations for wiring safety were found to be inadequate and the Federal Aviation Administration (FAA) began treating wiring as a system which eventually became better known as Electrical Wiring Interconnect System (EWIS).
While other branches of the United States Armed Forces have fully embraced treating their EWIS as its own system, the C-5 is currently the only platform for the Air Force to implement the EWIS program. Other USAF platforms have taken notice of the advancements made with C-5 EWIS and have plans to implement the EWIS program for their platforms in the near future.
KIHOMAC was awarded a five-year contract to provide analyses and engineering services to improve the safety, readiness and sustainability of the C-5 EWIS. The EWIS includes, but is not limited to, wiring, electronic warfare systems, avionics systems, electromechanical systems and associated equipment. The leadership and core members of this team have been providing EWIS support to the C-5 for over ten years.
Supporting the Air Force's EWIS Transformation
KIHOMAC supports C-5 EWIS work at our offsite Byron, Georgia Facility and onsite with our Government customer at Robins Air Force Base, Georgia. Our Wiring Integrity Reliability Enhancement Strategy (WIRES) team includes engineers, analysts and subject matter experts. We regularly participate and contribute to the DOD’s Joint Services Wiring Action Group (JSWAG) conferences. The joint service forum provides advancement in safety, reliability, maintainability and readiness of all DoD aircraft by improving EWIS and fiber optic cable systems. KIHOMAC’s C-5 EWIS Program Manager, Cheryl Brotherton, is a recipient of the JSWAG Lu Roberts award for outstanding contributions and support to the aerospace wiring and interconnect systems, as well as being the Data Committee Chairperson for the Air Force for JSWAG.
Further, in supporting our C-5 Government customer on the C -5 EWIS program, KIHOMAC provides detailed, quantitative engineering investigations and analyses addressing maintenance practices, reliability, failure elimination or control, safety/risk areas, training issues, parts obsolescence issues, design modification, technical publication issues, Computer Aided Design (CAD) drawing development and updates, new component selection and testing, as well as technical assistance with other maintenance and logistics issues using a structured engineering approach.
Our KIHOMAC staff has well over 75 years of combined experience writing Test Program Sets (TPS). For our current C-5 EWIS contract, we use ELITE programming language v2.08.005 in-house for programming development for use with the Automatic Wire Test Set (AWTS) GFE unit.
These services are benefiting the USAF by continuing to maintain the operational life cycle readiness and sustainability and safely reducing maintenance requirements and costs. Our efforts are helping keep C-5 fleet on time, and on mission, ensuring the success of the USAF core competencies of Rapid Global Mobility and Agile Combat Support.
