Textron Aviation has updated the Cessna Skyhawk’s engine with a Lycoming dual electronic ignition system (EIS), which is now standard on new-production Skyhawks. The airplane’s engine, a 180-hp, fuel-injected Lycoming IO-360-L2A, was previously equipped with two magnetos.
According to Textron Aviation, the SureFly-manufactured EIS makes maintenance more efficient and improves the operation of the engine. SureFly EIS has a 2,400-hour “operating service time” and requires no interim maintenance, compared with the typical 500-hour inspection requirement for most magnetos.
Additionally, the EIS improves engine starting, especially when hot, and helps the engine perform better and burn less fuel. Lycoming engineers worked with SureFly to develop the EIS.
“The incorporation of the dual electronic ignition system demonstrates Textron Aviation’s continued commitment to our piston aircraft, including the legendary Cessna Skyhawk, by easing operations for customers,” said Textron Aviation v-p of piston and utility sales Chris Crow. “With 70 years of proven performance, the aircraft continues to play a vital role in supporting pilots across the globe.”
More than 45,000 Skyhawks have been delivered since the model’s debut flight in 1955. Next week at EAA AirVenture 2025, Textron Aviation is celebrating the 70th anniversary since the C-172’s first flight.
