Six months into the renovations on our new, dedicated MRO facility in Tewkesbury, UK, we are excited to share an update on the progress, following our initial announcement of the investment in 2025.
The program is progressing well and we have already achieved several important regulatory milestones that bring us closer to supporting you from this new site.
Key Certification Milestones
In December 2025, the Tewkesbury site successfully passed a series of critical audits, establishing the regulatory foundation and international standard foundations required for future operations:
- BSI AS9100 certification
- Part 145 UK Civil Aviation Authority (CAA) approval
- Part 145 European Union Aviation Safety Agency (EASA) approval
This regulatory and international standard baseline also allows us to begin applying for additional global approvals.
Where you accept a UK CAA or EASA Form 1 release, these approvals will begin to support your requirements. For customers requiring a FAA or CAAC release, we can now progress these applications under the oversight of the UK CAA, further strengthening our ability to support your operations worldwide.
What Happens Next
We currently expect to begin transferring our first product lines to the Tewkesbury facility from March 2026 onwards. Detailed phasing plans for the initial work packages are being finalised, and you will be contacted directly in due course with specific information relevant to your programmes.
What This Investment Means for Means for You
Once complete, the Tewkesbury facility will give you access to a full, independent MRO capability designed to support you throughout the entire life of your aircraft and components.
From this site, you will benefit from lifetime repair and maintenance support, ensuring long-term continuity, consistent standards, and sustained product expertise well beyond entry into service. As the OEM for the products we support, you can rely on OEM-certified repairs, underpinned by deep engineering knowledge and OEM-pedigree parts.
Our OEM position allows us to deliver continuous parts reliability improvements, including repair enhancements, material upgrades, and obsolescence management, helping you reduce in-service issues, improve dispatch reliability, and lower total cost of ownership over time.
You will also be supported by a dedicated 24/7 Aircraft on Ground (AOG) service, giving you rapid access to technical expertise, spares, and repair solutions when operational continuity is critical.
Combined with the rest of our worldwide MRO and support network, the Tewkesbury facility strengthens our ability to support you wherever you operate, with consistent quality, responsive turnaround times, and regulatory approvals aligned to your regional and operational needs.
Dave Mayne, MRO Director for Europe says: "I am really pleased with the progress we are making in Tewkesbury. Our teams are working hard to launch the new site quickly so we can begin delivering the benefits of a dedicated MRO facility to our customers. Every decision - from product to people to process - is guided by that goal."
Brian Sartain, Chief Operating Officer of Ontic, said, “The opening of our Tewkesbury MRO facility marks a step-change in how we support our customers. By consolidating all our UK aftermarket expertise in one dedicated site, we are investing in the people, capability, and infrastructure to consistently deliver a faster, more responsive and more transparent service. Alongside our new Miramar facility in the US, this is a significant milestone in our commitment to keeping established fleets flying safely for decades to come.”
