Aircraft Accessories of Oklahoma is proud to offer SureFly FAA-certified electronic magneto replacements.

The SureFly Ignition Module (SIM) is a solid-state system that replaces one traditional magneto, typically the left or impulse-coupled/starting magneto on most aircraft engines. Available for 4- and 6-cylinder Lycoming and Continental engines, the SIM eliminates magneto maintenance, overhauls, and rebuilds—helping you cut associated costs in half.

Many fixed-wing single-engine aircraft can take advantage of SureFly’s advanced timing feature, improving cruise flight efficiency. Additional aircraft will gain this capability as the FAA expands SureFly’s Airframe STC AML.

Note: SureFly SIMs require a Slick-style ignition harness. If you are replacing a Bendix-style magneto, Aircraft Accessories of Oklahoma can help you source a Slick harness. For aircraft with pressurized magnetos, turbocharged engines, or operations routinely above 10,000′, contact us for guidance on harness selection.

SureFly complements our expert magneto repair services, giving aircraft owners the choice of traditional magnetos or cutting-edge electronic ignition solutions—while maintaining the quality and reliability Aircraft Accessories of Oklahoma is known for.
