Lycoming Engines introduced the Lycoming Electronic Ignition System (EIS) on opening day of EAA AirVenture Oshkosh 2019.
The Lycoming EIS is a drop-in replacement for magnetos and provides easy installation and engine startability, according to company officials.
“Lycoming’s pursuit of electrical engine technology supports improvements in aviation safety, durability, and performance,” company officials said in a prepared release.
“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,” officials continued.
Lycoming officials added they have 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,” said Shannon Massey, Senior Vice President and General Manager of Lycoming.
Lycoming is in the process of obtaining FAA certification for the new ignition system.
Meanwhile, 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 aftermarket customers will be via Approved Model List (AML) supplemental type certificate (STC). Lycoming is currently working with an STC provider for the aftermarket portion of the project, officials note.
CubCrafters is Lycoming’s 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 CC-19 XCub (pictured above).
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 its existing Cessna aircraft fleet, Lycoming officials said.

What’s that big gear sticking out of it? That sure looks like it would be a moving part to me.
Paul Millner says
Hi Tom, these SureFly (not sure fire) systems that Lycoming is rebranding do require a source of electricity, about one amp.
To install two, no backup magneto, requires a small, about 5AH, battery for backup.
Yup, approved for Continentals as well… and SureFly plans to offer the two units plus a battery option as well…
Tom Charlton says
* Can I assume that, like a magneto, this system is independent of any air frame electrical system?
* Wondering if this system will eventually be available / adaptable to Continentals?
Well finally someone had the idea that some of the AC engines
should come out of the dark ages

Hmmmm….? This looks exactly like the recently certified SureFly mag replacement.!
I’m sure that Lycoming will sell more of these than Surfly will just because of the name.
Now, is the price the same ?
richard heinichen says
I just declared a in flight emergency after installing the sure fire in my C182S.
I’m stuck 1000 miles from home.
Jeff Pierson says
Did the remaining source, your magneto fail also? Why was losing one ignition an in-flight emergency?
Tom Charlton says
When one ignition system fails you can’t know why. Could be something that’s about to cause system number two to fail also. Give ATC a clue and let prudence determine when and where to land for repairs.
Craig Lawler says
What was the cause of the failure?
Surefly is already cleared for one mag/EIS and will soon be getting the second EIS.
