Ontic has officially opened a new dedicated Maintenance, Repair and Overhaul (MRO) facility in Tewkesbury, Gloucestershire, bringing around 200 specialists together as part of a $30 million global investment in its aftermarket support capabilities.
The purpose-built 72,000 sq ft site will strengthen the aerospace supplier’s ability to support airlines and aircraft operators worldwide, providing specialist repair and maintenance services for components across established civil and military fleets.
The Tewkesbury facility forms part of Ontic’s wider investment in MRO capacity on both sides of the Atlantic, alongside its new facility in Miramar, Florida. The investment is intended to improve customer support, increase repair capacity and help keep aircraft and their components in service for longer.
The new Gloucestershire site brings together engineers, technicians, customer service teams, supply chain specialists and logistics personnel under one roof. Its facilities include dedicated pneumatic and hydraulic infrastructure, an avionics workshop with an ISO 7 clean room, non-destructive testing capability, a machine shop and a dark room. Additional space has also been incorporated to accommodate future expansion.
The facility achieved BSI AS9100 certification in December 2025, alongside Part 145 maintenance approvals from the UK Civil Aviation Authority (CAA) and the European Union Aviation Safety Agency (EASA). Federal Aviation Administration (FAA) approval has also been awarded under CAA oversight.
Ontic is continuing to work towards Chinese Civil Aviation Administration (CAAC) approval, which the company expects to secure in early October 2026. Product lines are now being transferred to Tewkesbury as the site builds towards full operational capability.
As a licensed original equipment manufacturer (OEM) for thousands of aerospace product lines, Ontic has access to the proprietary technical data, tooling and test equipment needed to repair components to original manufacturer standards.
This allows the company to provide warranty-backed repairs while drawing on its original design and manufacturing expertise. The approach is intended to give operators continued access to specialist support for aircraft components throughout their operational lives, including after the original aircraft manufacturer has moved on to newer products.
The Tewkesbury facility will also support improvements in component reliability through repair enhancements, material upgrades and obsolescence management. These services can help operators reduce recurring technical issues, improve aircraft dispatch reliability and manage maintenance costs over time.
Ontic’s dedicated 24-hour Aircraft on Ground (AOG) service will provide additional support when aircraft are unexpectedly grounded, helping customers access technical expertise, spare parts and repair solutions when time is critical.
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.”
Dave Mayne, MRO Director for Europe at Ontic, added: “I am really pleased with the progress we have made in bringing Tewkesbury to life. Our teams have worked 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 – has been guided by that goal.”
The opening represents a further investment in the UK’s aerospace aftermarket sector, bringing specialist engineering expertise and maintenance infrastructure together at a single Gloucestershire location.
Combined with Ontic’s international MRO and support network, the new facility is intended to provide operators with consistent repair standards and responsive turnaround times, helping maintain the availability of aircraft systems and components across a range of established fleets.
