What is Lycoming EIS?

The Lycoming EIS is a drop-in capable replacement for magnetos that provides easy installation and engine startability. Improved reliability in reciprocating engine ignition systems is a key safety enhancement.

The Lycoming EIS accomplishes this enhancement by using a solid-state design that has no moving parts and almost completely eliminates scheduled maintenance requirements.

How long will the Lycoming EIS run if the alternator breaks?

The answer to this question depends on what capacity battery is installed in your aircraft, the health of that battery, and whether you have a back-up battery installed.

The EIS has low current draw and a lower voltage shut-off than most avionics packages. The low voltage cut-off is somewhere around 8V, so most aircraft avionics will shut off prior to your EIS.

Lycoming does not recommend operating an EIS-equipped aircraft on a jump-started, or weak battery. We recommend that all recommended battery maintenance be followed in accordance with the manufacturer’s recommendations.

When can I buy Lycoming EIS for my aircraft?

Certified Lycoming EIS is available for a single installation immediately for all Lycoming engine models listed in the current revision of Lycoming Service Instruction 1443.

Lycoming is currently working with a well-established STC provider to create the airframe STC required for dual-installation for aftermarket customers.

Experimental Lycoming EIS is available immediately for all experimental Lycoming engines – both in single, or dual installation. You should review the current revision of Lycoming Service Instruction 1443 or contact Lycoming to determine the appropriate EIS part number for your installation.

Does Lycoming EIS provide cost savings to customers?

For someone who is operating magnetos in general, the cost of operating and maintaining one magneto until TBO is approximately $3,000-$3,500. When you replace it with EIS you virtually eliminate those maintenance costs.

Therefore, by switching to a dual Lycoming EIS, you can eliminate nearly $6,000-$7,000 in costs through TBO.

Fleets also have an opportunity for cost savings by switching to Lycoming EIS. Fleet operators can investigate how much they are spending on magneto maintenance, as there is a good chance that moving to EIS could save them significantly in maintenance costs.

The cost for a Lycoming EIS is competitive in price with options already available on the market.

What is the ‘myth’ about Lycoming Factory Engine?

The myth is that there will be chargebacks once the core engine has been inspected at the factory. This cannot be further from the truth.

In fact, so long as the like-model, operating core engine follows the policy outlined in Lycoming SL250A, there will be no penalties or charge-backs.

What does it mean to get a rebuilt engine?

Get an absolute zero-time since new engine from the Lycoming factory; only the original engine manufacturer can rebuild your engine to meet the exact, new engine specifications that a rebuilt engine requires…

Lycoming rebuilt engines are built on the same assembly line as new and overhauled engines, following the same quality processes and manufacturing standards. Rebuilt engines carry a two-year warranty, or to full TBO – listed in Lycoming Service Instruction 1009 – whichever occurs first.

What does it mean to get an Overhauled engine?

A Lycoming overhauled engine puts you back in flight in no time. Exchange your like-model complete operating engine with no charge-backs and update to the most current features and parts, backed by a Lycoming warranty.

Factory overhauled engines carry a one-year warranty or to full TBO listed in Lycoming Service Instruction 1009, whichever occurs first.

What's the difference between Field Overhaul and Factory Overhaul?

A Factory Overhaul is always built with 100% genuine Lycoming parts, but this is not always the case with a Field Overhaul. Genuine Lycoming roller tappet technology upgrades are offered at no additional cost with a Factory Engine. (Crankcase and crankshaft replacements, if unserviceable, are also done at no additional cost.)

A Field Overhaul will require additional payment for updating roller tappet technology and crankcase and crankshaft repairs. In addition, Factory Overhauls come with a one-year limited warranty, while a Field Overhaul typically comes with a six-month warranty.

The Lycoming Standard has been in the making since 1929, when Lycoming began producing piston aviation engines and parts from its factory in Williamsport, Pennsylvania.

This standard can be experienced by using genuine Lycoming parts and engines. Because an engine is the sum of its parts, and genuine Lycoming parts make all the difference. Experience the Lycoming standard with genuine Lycoming parts and engines from Airpart Supply.
