Certification and testing

Certification and testing

Since our first airfield opened in Cambridge in 1929, Marshall’s engineers and pilots have flown, maintained, repaired, modified and trained aircrews on hundreds of types and variants of aircraft models - from light aircraft to commercial airliners.

Over millions of work hours and flight hours we have created, built, tested and self-certified experimental designs and novel modifications from the legendary Concorde nose to the Airbus A400M’s engines.

Meanwhile, we have witnessed and contributed to the evolution in global regulations and airworthiness standards over generations, ensuring that we have always stayed at the forefront of the latest developments, from safety and communications protocols to uncrewed aerial systems (UAS).

Building on this heritage and applying our vast expert technical and regulatory knowledge, we offer full-fledged testing (both flight and static) and independent certification of all the work we perform - from routine maintenance to major structural modifications and system integrations.

Additionally, we offer third-party certification advisory programmes that can take our customers’ products, modifications or systems from design through to real-world operation and beyond.

Airworthiness certification

Alongside the continued airworthiness management we perform as part of our core maintenance, repair and overhaul (MRO) offering, we are able to independently self-certify our own work on major modifications and integration of new systems into aircraft.

Furthermore, we offer specialist third-party airworthiness assessment and certification support at every stage of the product lifecycle - from initial design through to in-service modifications and integration of new systems.

Drawing equally on our decades of aviation engineering expertise and wealth of certification knowhow, we can provide practical and informed recommendations that take relevant civil or military aviation regulations into account, charting a path to airworthiness certification for even the most complex and advanced aircraft or air system.

We can scale our service from initial airworthiness advice and technical evaluations (for components and aircraft alike) to step-by-step assistance with formal certification processes and post-certification compliance audits.

Flight testing

Marshall is proud to provide a full suite of military and civilian flight test capabilities, both as a standalone service and in complement to our provision of maintenance, repair, overhaul (MRO) and engineering projects for existing customers.

We have the people, resources and expertise to conduct experimental, developmental and production flight test, providing everything from routine post-maintenance checks to complex trials of heavily modified aircraft. Depending on customer preferences and requirements, all work can be undertaken solely by Marshall, or as part of a combined test team.


Our flight test capabilities

Ground testing

In addition to airworthiness certification and flight testing, Marshall performs a broad array of ground-based testing, both as an independent service for third parties and for structures or components we are designing or manufacturing under contract.

Marshall maintains the largest Ground Running Enclosure (GRE) and compass swing bay in Europe, measuring 90m wide and 20m high.

The multi-million-pound facility enables us to offer an unmatched engine test service, allowing conditioning of the airflow to the propellers and jet engine intakes and accommodating aircraft up to the size of a Boeing 747-400 – while significantly reducing noise during testing.
