Lycoming IO-390 Aircraft Engine
Key Features:
Fuel Injection: Provides precise fuel delivery, improved efficiency, and better performance at varying altitudes. Lightweight Design: Optimized for light sport, experimental, and modern certified aircraft. High Power-to-Weight Ratio: Delivers strong performance for its size. Modern Engineering: Incorporates advanced materials and design for improved durability and reliability. mooth Operation: The horizontally opposed configuration reduces vibration.
Popular Models in the IO-390 Series:
The IO-390 series includes several models, each tailored for specific aircraft and performance requirements. Some of the most common models are:
IO-390-C (IO-390-C1B6, IO-390-C3B6): 210 hp, used in experimental and light sport aircraft like the Van's RV-14 ,Cirrus SR20. IO-390-A (IO-390-A3A6, IO-390-A3B6): 210 hp, used in certified aircraft like the CubCrafters XCub. IO-390-EXP119: A variant designed for experimental aircraft with specific performance requirements.
Applications:
The IO-390 series powers a variety of aircraft, including:
Experimental and Kit-Built Aircraft: Such as the Van's RV-14, RV-10, and other high-performance homebuilts. Certified Aircraft: Like the CubCrafters XCub and Carbon Cub SS. Light Sport Aircraft: Ideal for modern LSA designs requiring a compact, high-output engine.
Maintenance and TBO:
TBO (Time Between Overhauls): 2,000 hours or 12 years, whichever comes first (under normal operating conditions). Maintenance: Regular oil changes, inspections, and adherence to Lycoming's service bulletins are essential for optimal performance.
Advantages:
Efficiency: Fuel injection and modern design contribute to better fuel economy. Performance: Ideal for aircraft requiring a compact, high-output engine. Versatility: Suitable for both experimental and certified aircraft. Reliability: Built with modern engineering and materials for enhanced durability.
Comparison to IO-360 Series:
The IO-390 is a larger-displacement engine (390 cubic inches vs. 360 cubic inches) and produces more power (210 hp vs. 180-200 hp).
It is often chosen for aircraft requiring higher performance or for upgrades to older airframes.
