100,000+ Repair Capabilities
Repair & Overhaul Capabilities
Two dedicated departments test, repair, and overhaul the instrumentation your aircraft depends on — from primary flight instruments to autopilot computers.
Air Shunt Instruments, Inc. is an FAA-certificated Part 145 repair station — certificate YD2R315L — in Chatsworth, California. We maintain over 100,000 repair capabilities across military and commercial avionics instrumentation, backed by more than 10 million spare parts on hand.
Work is split between two departments on the same site. Cockpit & Controls handles the computers, amplifiers and gauges behind the panel. Flight Instruments handles the indicators in it. Because both are in house, an indicator and the box driving it can be diagnosed together instead of being shipped to two vendors.
