Since 1943, ECi has been a proud participant in the segment of aviation dealing with piston powered aircraft. With roots dating back to WWII when ECi was known as Pennington Channelcromium Co., the Army Air Force and the Navy relied on the corrosion and wear properties of chromium plated cylinder barrels produced by PCC. Although chromium plating was considered state of the art 60 years ago, ECi has over the intervening years moved on to new plating technology as well as other innovative and high quality repair processes for all major components of a certificated aircraft piston engine.
