The Grumman G-164 Ag-Cat is a rugged agricultural biplane that became one of the most successful crop-dusting aircraft in American aviation history. First flown in 1957, the Ag-Cat was Grumman's entry into the civilian agricultural market, applying the company's legendary structural engineering from naval fighters to the demanding world of low-altitude aerial application. Built with a steel-tube fuselage and fabric-covered wings, the biplane configuration provided exceptional slow-flight handling and the ability to operate from short, unprepared strips adjacent to fields. The design proved so durable that Ag-Cats remained in production for over three decades, with more than 2,400 built across multiple variants powered by radial engines ranging from 220 to 600 horsepower. The type's wide-track landing gear, excellent visibility from the elevated cockpit, and ability to carry chemical loads up to 2,000 pounds made it ideal for agricultural operations across North America. Many Ag-Cats accumulated tens of thousands of flight hours in service, a testament to Grumman's "built like a tank" philosophy. While newer turbine-powered ag-planes have largely replaced it in commercial fleets, the Ag-Cat remains beloved among operators for its simplicity, reliability, and forgiving flight characteristics at the low speeds and altitudes where aerial application work happens. SkyMeter has tracked 90 flights across 2 airframes and 2 operators, with STORM FLYING SERVICE LLC the largest observed operator.
Safety in context
The incident rate counts flights with ANY safety event detected by SkyMeter: go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
