Lycoming Introduces Electronic Ignition System

News 07.21.19

Oshkosh, WI – 22 July 2019 – Lycoming Engines, an operating division of Avco Corporation, introduced the Lycoming Electronic Ignition System (EIS) today during its press conference at EAA AirVenture in Oshkosh, WI.  The Lycoming EIS is a drop-in capable replacement for magnetos and provides easy installation and engine startability. 

Lycoming’s pursuit of electrical engine technology supports improvements in aviation safety, durability, and performance.  As to safety, the General Aviation Joint Steering Committee (GAJSC), a public-private partnership working to improve general aviation safety, has identified improved reliability in reciprocating engine ignition systems as a key safety enhancement.  The Lycoming EIS accomplishes this enhancement by using a solid-state design that has no moving parts, is designed to go to Time Between Overhaul (TBO), and has no scheduled maintenance requirements. 

The Lycoming EIS was developed to meet the needs of our customers. Lycoming has received numerous customer requests for an electronic ignition system option for their Lycoming engine. 

“We are pleased to bring Lycoming EIS to the market and offer this new option to our customers,” stated Shannon Massey, Senior Vice President and General Manager of Lycoming.

Lycoming is the process of obtaining FAA certification for this new ignition system.

Lycoming EIS is available immediately for all experimental Lycoming engines in a fixed timing configuration, in both single or dual installation.  Single and dual Lycoming EIS installation will soon be available for Original Equipment Manufacturers (OEMs) via amended Type Certificate. Installation approval for our aftermarket customers will be via Approved Model List (AML) supplemental type certificate (STC). Lycoming is currently working with a well-established STC provider for the aftermarket portion of the project. 

CubCrafters is Lycoming’s strategic OEM launch customer for dual Lycoming EIS.  Lycoming’s IO-390-D3B6, marketed under the CubCrafters trade name CC393i, is a new high-performance engine that includes the dual Lycoming EIS and powers CubCrafters flagship personal adventure aircraft, the CC-19 XCub.

Additionally, Textron Aviation is working with Lycoming on integrating Lycoming EIS into new Cessna OEM aircraft.  Textron Aviation also intends to work with Lycoming on aftermarket implementation for their existing Cessna aircraft fleet.
