Pacific Southwest Instruments

Pacific Southwest Instruments, known as PSI, repairs, overhauls and exchanges aircraft instruments and avionics. It is based in Corona, California, in the United States. The company was founded in 1982.

PSI set out to give customers good products and the best service it could. It says steady growth and worldwide acceptance show that customers value the quality and support. It describes itself as a major instrument repair, overhaul and exchange company.

The company knows that aircraft down time is stressful and costly. Callers speak with aviation staff who can give advice or technical help. PSI offers fast turn around times and a large exchange inventory so that aircraft can return to service sooner.

PSI runs a modern shop with a large inventory of parts. It also does its own engineering. The company says its engineers have developed processes that prolong the life of instruments and avionics, which helps lower customers' running costs. It publishes a capabilities list that customers can download.

Several product areas show this work. PSI supplies DER replacements for many Ametek indicators, including LCD engine gauges. It offers DER replacement clock displays, batteries and switches for GE and Air Precision clocks. It has developed processes to extend the life of the Citation analog vertical tape gauge and displays. It also provides repair, overhaul and exchange for BAE flight deck controls and avionics.

PSI's customers are found worldwide. The company says aviation professionals in North and South America, Asia, Europe, Australia and Africa rely on it for instrument and avionics service.
