Understanding aviation maintenance is never easy. In fact, it’s becoming more challenging everyday. As you face continuing budget constraints, growing federal regulations, and increasing demand for higher reliability, you need a partner you can depend on.

How often have you needed instrument support in the middle of the night, or were stranded in a remote location of the world due to an instrument-related failure? If you have used UNDERWOOD-Instrument Services (U-ISi) in these extreme situations, you know that your aircraft was AOG for the minimum amount of time possible. We know that downtime is lost time and we hate lost time. No matter what your instrument requirements may be, UNDERWOOD-Instrument Services only employs experienced technicians which are available 24 hours a day, seven days a week to answer your call and respond to your needs.

UNDERWOOD-Instrument Services provides total instrument support on both fixed-wing and rotor aircraft to corporate, regional and commercial airlines, and government organizations worldwide. We also provide telephone technical support and on-site troubleshooting.

Inventory of parts and materials to ensure a rapid repair and turnaround of your instrument is one of our service goals.

Not many companies can say that and back it up with proven performance.
