Johnston Aircraft Service, Inc. has been a fixture in California’s agricultural aviation community since 1947. Located at Mefford Field Airport (TLR) in Tulare, in the heart of the Central Valley, they provide Satloc GPS guidance system sales, installation, parts, and service support for aerial applicators across the region.

The company originally got its start converting surplus military Stearman biplanes for aerial application work and grew steadily through the following decades to become a dealer and distributor for multiple ag aircraft manufacturers. Their facility includes a full engine overhaul department, airframe shop, and extensive parts inventory. Johnston Aircraft supports a wide range of ag aircraft platforms including Thrush, Piper Brave, and Piper Pawnee, and also serves as a Cessna agricultural support center.

As an authorized Satloc dealer, Johnston Aircraft provides local expertise for Satloc’s full product line, including Falcon and Falcon Pro GPS guidance systems, IntelliFlow dispersal controllers, and related avionics. Their on-site team can assist with installation, calibration, troubleshooting, and parts for Satloc equipment. For more information, visit johnstonaircraft.com.
