What Pacific Southwest Instruments does
Pacific Southwest Instruments (PSI), founded in 1982 by Jim Joubert, is a privately-held aircraft instrument and avionics repair, overhaul, and exchange company headquartered in Corona, California. The company provides MRO services for legacy aircraft instruments and avionics, including proprietary DER (Delegated Engineering Representative) replacement solutions for Ametek engine gauges (DHC-8, EMB-120, SAAB-340 platforms), GE and Air Precision electronic clocks (DASH 8, CRJ, ERJ 145, ATR 42, Airbus A320/A330/A340, Boeing 737/747/757), Cessna Citation vertical tape gauges, and BAE/Boeing flight deck controls. PSI holds FAA CRS (#KD3R627L), EASA Part-145 (#EASA.145.4723), and UK CAA certifications, enabling it to serve aircraft operators and MRO facilities globally across North and South America, Europe, Asia, Africa, and Oceania.
The company generates revenue through three primary streams: standard repair and overhaul services, an exchange program where customers receive certified overhauled units in return for rebuildable cores at flat-rate pricing (warrantied 12 months/1000 hours overhaul; 6 months/300 hours repair), and value-added engineering services for legacy avionics. Its go-to-market is sales-led and direct, relying on toll-free phone contact, RFQ form submissions, and downloadable capability documents — all services delivered from the single Corona facility. PSI serves both aircraft operators (commercial and private) and third-party MRO facilities, with no external equity investment, parent company, or acquisition activity documented. The founder remains CEO/President after 44 years, and the company's competitive position rests on specialized engineering capability, multi-jurisdictional regulatory certifications, and a large exchange-pool inventory for legacy avionics platforms.
