What does 'unlimited' class rating mean?

Our unlimited class rating means we can add new part numbers to our repair capabilities within the three accessory classes without being restricted to a pre-defined list. This gives us flexibility to support customer fleet requirements as they evolve.

How often are your certifications audited?

We undergo FAA surveillance inspections typically 2-3 times annually, EASA annual audits, periodic OEM supplier quality assessments from Lockheed Martin and Bombardier, customer audits, and monthly internal audits to proactively identify improvement opportunities.

What quality management standards do you follow?

We're certified to ISO 9001 aerospace standards, which requires documented processes for all key activities, regular internal audits, management review of quality metrics, and ongoing verification that our quality system remains effective.

Aviation Certifications - FAA/EASA/CAA Part 145 Approved

Q: Can you service European-registered aircraft accessories with your EASA approval?

Yes. Our EASA Part 145 approval (145.4452) authorizes us to perform certified aircraft accessory overhaul services on European-registered aircraft. Our EASA scope maintains equivalency with our FAA scope for seamless international service.
