• Avionics laboratory for design, manufacture, overhaul and testing of flight control electronics, power supplies and relay panels
• Protective coatings to MIL-PRF-23377 and MIL-DTL-53039 in environment controlled booths, with checks of adhesion, thickness and finish
• Precision gear manufacturing, machining and CMM inspection, with dimensional measurement, surface finish verification and documentation for traceability
• Assembly manufacturing with in-house production teams and a certified vendor network

FAA-PMA process

The company says its PMA work follows FAA design approval standards. Each part goes through engineering design, test verification and final FAA submission, and engineers check form, fit, function and airworthiness against OEM specifications, working with operators and procurement teams.

Source approval and government work

Rotair reports more than 40 years of experience with source approval and government procurement. It prepares and submits Source Approval Requests for Critical Safety Items under the Defense Federal Acquisition Regulations, and has a service that builds the request packages, with ongoing liaison with government agencies. Its customers include military commands, DLA procurement and commercial operators.
