Design and documentation
support that plugs into your team

Whether you are running an STC, a field approval, or a one-off modification, I provide the design data and documentation alongside your DER, project lead, or shop. You stay in control of the program. I deliver the work.

1

Scope & Intake

You describe the modification, the airframe, and the deliverables you need. I confirm scope, timeline, and standards in a short technical proposal so we are aligned before any work begins.

2

Build & Iterate

I build the drawings, analyses, and certification documentation to your spec and the applicable FAA standards. Markups and revisions come back fast so the package keeps moving.

3

Review-Ready Hand-Off

Deliverables are formatted and assembled for your DER, IA, or program lead to review and sign off. I stay engaged through revisions until the package is accepted.

The specialist behind
the work

Verso Avionics is the independent practice of an avionics design specialist focused on aircraft modification programs. Ten-plus years building wiring diagrams, electrical analyses, and certification documentation across transport-category fixed-wing, heavy rotorcraft, and business jets. Eight-plus years before that on the hangar floor — heavy maintenance, MRO, troubleshooting, and manufacturing — installing and supporting the same systems I now design.

Design and documentation is what I do best. What separates this work from a design-only practice is the eight-plus years before it on the hangar floor: components specced by someone who has installed them, systems designed by someone who has troubleshot them on the line, harness routes drawn the way they actually fit in the airframe. That removes the gap between a clean drawing and a clean installation, where most packages lose time and rework dollars.
