Airfield Systems Maintenance

DSI maintains what aviators use to navigate through the National Airspace System. Our services include corrosion control, major and minor scheduled and unscheduled maintenance, and preventive maintenance inspections.

DSI maintenance technicians are extensively trained and qualified not only on legacy systems, but on the latest in navigational equipment. All technicians are licensed by the FCC and each technician holds a SECRET clearance. DSI maintenance technicians coordinate with the FAA Flight Inspection Field Office for required flight checks of Navigational Aids.

Preventive maintenance inspections are an integral part of our overall maintenance management process. These inspections ensure that we maintain critical uptime rates well above the established standards for all assigned equipment.

Detailed equipment maintenance documentation is vital to ensure proper procedures have been accomplished and technical orders followed. DSI management uses the latest Computerized Maintenance Management System (CMMS) to track maintenance actions and to alert management of negative trends before they become major issues.
