it doesn’t matter if the aircraft is for military or commercial application, we love our acronyms. lately, i have noticed more and more references to the acronym ewis. ewis means any wire, wiring device, or combination of these, including termination devices, installed in any area of the aircraft for transmitting electrical energy, including data and signals between two or more intended termination points. ewis is basically the wiring system of an aircraft, including all the wiring harnesses that interconnect currently makes for various aerospace and defense companies and countries. so, i wondered why ewis seemed so much more prevalent today than in the early 1990s when john and i started interconnect wiring. here is what wikipedia says: prior to the aviation accidents of twa flight 800 and swissair 111, the wiring on aircraft was a minor concern. the following is an excerpt from the faa’s regulations released november 8, 2007 governing aspects of ewis on aircraft as to the reason for the increased concerns regarding ewis: “safety concerns about wiring systems in airplanes were brought to the forefront of public attention by a mid-air explosion in 1996 involving a 747 airplane.
ignition of flammable vapors in the fuel tank was the probable cause of that fatal accident, and the most likely source was a wiring failure that allowed a spark to enter the fuel tank. although an exact cause could not be determined, the presence of re-solidified copper on a portion of a wire of the in-flight entertainment system cable indicated that wire arcing had occurred in the area where the fire most likely originated. deteriorated wiring, corrosion, improper wire installation and repairs, and contamination of wire bundles with metal shavings, dust, and fluids (which would provide fuel for fire) were common conditions in representative examples of the ‘‘aging fleet of transport airplanes.’’ unfortunately, like commercial aerospace, defense aircraft, including fighter jets and utility helicopters, have experienced significant ewis issues as well. kapton wire has been a problem for many aircraft including the f-16, f-15, and the uh-60. ewis in a nutshell. we are the sole licensee of lockheed martin for f-16 electrical products. we also have a technical services agreement with sikorsky for all of their aircraft.
in the aviation industry, we sure love using acronyms. it doesn’t matter if the aircraft is for military or an electrical wiring interconnect system (ewis) is the wiring system to gather industry leaders examine the current state of aging aircraft systems; one of the main areas examined included ewis. training related to electrical wiring interconnect system (ewis) was introduced by european aviation, ewis training ppt, ewis training ppt, ewis pdf, ewis inspection, ewis faa. an electrical wiring interconnect system is the wiring system and components for a complex system. the term originated in the aviation industry but was originally designated as electrical interconnection systems.
a united airlines b767-300 on a jan. the maintenance of aircraft ewis analysis and wiring systems since 2010 sofema aviation services has started to deliver ewis training both as open training courses and in company electrical wiring interconnect system ewis training was issued as an easa requirement in the summer of 2008., ewis training questions, ewis easa, ewis training requirements, ewis analysis
When you search for the ewis aviation, you may look for related areas such as ewis training ppt, ewis pdf, ewis inspection, ewis faa, ewis training questions, ewis easa, ewis training requirements, ewis analysis. what does ewis stand for? what are the three different wiring malfunctions? why is aircraft wire stranded? how do you check an aircraft wiring?
