  • Aging Aircraft Structure, Systems, and Wiring. Our DER's are current on issues of aging aircraft structure, systems, and wiring.

  • Subsystem Component Monitoring and Data Gathering. Davidson Engineering Resources, Inc. has embarked on the development of an STC that gathers operational parameters of non-integrated subsystem components. This STC is in direct response to aviation industry requirements for improved maintenance visibility and susequent maintenance actions based on "REAL DATA" instead of hunches and maybe's. This STC is being developed to be flexible and directly support airline, business jet (Part 25 and Part 23) maintenance programs. Systems targeted are: Air Conditioning & Pneumatics (valves, heat exchangers, ducting), Electrical (voltage / current signatures of various components), Hydraulics (pressures), and other systems designs are on the drawing board.
