Certified: Lycoming IO-390-A1A6

FAA Approves Type Certification

Lycoming has yet another TC under its belt... as the FAA has certified the IO-390-A1A6.

Lycoming tells us that they developed the certified IO-390 in response to airframe manufacturers and aircraft owners who have requested a higher horsepower, four-cylinder engine. For several years, the uncertified version of a 390 Lycoming engine, the IO-390-X, has been powering many homebuilt and kit aircraft in the experimental market.

The certified IO-390 Lycoming engine, at 312 to 315 pounds and a rated 210hp at 2700 rpm, uses the same footprint and delivers more horsepower than the IO-360-A Series Engines. The four-cylinder, fuel-injected IO-390-A1A6 includes a robust rotating system, specifically developed cylinders, tuned induction system, Lycoming's roller tappets, Slick Start ignition, and front facing fuel servo. Following this first model, Lycoming will continue to certify different versions of the IO-390 to fit customer requirements.

Lycoming expects to begin shipping the engines next month.
