Why FHB
The rare shop that tests what it builds.
Most harness shops hand you a bundle. We hand you a bundle and the test record that proves it will work.
Credential
35+ years aviation wiring
22 years U.S. military aircraft electrical systems plus 15 years civilian aviation repair. Fred brings that discipline to every bundle that leaves the bench.
Testing
Continuity, Hi-Pot, visual
Every harness is tested end-to-end, documented, and labeled. You get a record of the work, not a verbal assurance.
Ownership
Veteran-owned, Navarre FL
Fred and Hyang Ok Bernsdorf own and run the shop. You talk to the people doing the work — not a dispatcher.
Bench log · recent
Every bundle, every test, documented.
Five of the last jobs to leave the bench. Each harness ships with its test record attached and a serial tag riveted to the backshell.

How it works
Three steps from idea to finished bundle.
Built, tested, labeled.
We build to your spec. Shielding dress, connector termination, continuity and Hi-Pot, visual inspection — every leg. Labels applied, photographs taken, test record filed.
Shipped with the record.
You receive the bundle, the test record, and the label log. If something doesn't sit right in your install, we stand behind the work.
