OEM Manufacturing

From Boeing Defense & Space:

“With today’s shipment of the reference Fuel Quantity Test Cable Set I wanted you to know that Boeing appreciates the enormous engineering effort and assistance you provided to Boeing AWACS Engineering to bring the subject cable set into a workable configuration. Without your engineering effort, persistence and patience the cable set would still not be in a workable configuration. Again, thank you for the outstanding effort.”

From Legacy Domestic Airline Tooling Services:

“After 40 years my retirement date is set for July 1, 2008. It has been an honor and a pleasure working with 4M Sigma over the years. Your service and your products have always been top of the line. Keep up the great work you’re a great company to deal with.”

From Defense Logistics Agency Procurement Contractor:

“Thanks for your persistence to provide quality work. It is greatly appreciated.”

From Legacy Domestic Airline:

Project Engineering

From Olin Aerospace (V-22 Wing Fire Protection System Program)

“I would like to express my appreciation for your efforts in the development of the optical fire detectors and interconnect cables for the V-22 system. Your knowledge of electronic systems requirements streamlined the complex task of developing specifications for these products jointly with the customer (Bell Helicopter) and the supplier (SBRC now part of Kidde Aerospace). There were numerous difficulties involved in defining a workable configuration for the interconnect cables, but your expertise in this area allowed you to guide the customer in specifying a product that would both meet demanding requirements (survivability in 10,000 V/m EMI environment) and be readily manufacturable.”
