As the global aerospace industry gathers this week at Farnborough International Airshow, much of the conversation will centre on new aircraft programmes, production rates and record order books. Yet behind the headlines lies another rapidly growing market that many believe could shape the industry's future just as profoundly: Maintenance, Repair and Overhaul (MRO).
With airlines extending the operational lives of aircraft, new engine platforms generating more complex maintenance requirements and manufacturers working to improve fleet availability, MRO has become one of aerospace's fastest-growing strategic sectors. A recent report from the National Manufacturing Institute Scotland (NMIS) estimates that the UK's aerospace MRO market could grow from around £4 billion today to as much as £15 billion with the right investment in technology, skills and innovation. It also warns that without a coordinated digital strategy, Britain risks losing workshare to better-prepared international competitors.
For Derby-based digital validation specialist AddQual, the opportunity extends beyond expanding maintenance capacity. The real challenge is helping engineers make better decisions, faster. Managing Director Ben Anderson believes digital validation is becoming one of the industry's most valuable productivity tools.
"Aircraft generate extraordinary amounts of inspection data throughout their lives," he said. "Every maintenance event creates measurement reports, borescope imagery, inspection records, engineering documentation and quality evidence. The challenge isn't collecting more data. It's turning that information into confident engineering decisions quickly enough to keep aircraft flying."
While much of the industry's investment has focused on automation, robotics and artificial intelligence, Anderson believes the next competitive advantage lies in connecting inspection evidence with engineering decision-making.
"The bottleneck isn't always the maintenance itself," he explained. "It's often the time taken to validate inspection results, review evidence, produce reports and gain confidence that components are ready to return to service. Every unnecessary delay impacts aircraft availability."
That challenge has become increasingly significant as aerospace organisations adopt more digital inspection technologies. Each inspection produces larger volumes of information than ever before, yet much of that data remains fragmented across multiple systems. AddQual developed its MiDAS platform specifically to address this growing complexity. Rather than simply storing inspection records, MiDAS creates a connected digital environment where inspection data, quality evidence, engineering knowledge and traceability are brought together into a single validated workflow. The result is faster reporting, improved collaboration and greater confidence in every engineering decision.
"As the industry embraces AI and digital inspection technologies, manufacturers need confidence that every recommendation is supported by complete evidence and full traceability," Anderson said. "MiDAS provides that digital thread. It connects people with information, allowing engineers to understand not only what they're looking at, but why a particular decision has been reached."
That capability is becoming increasingly valuable as regulators, OEMs and airline customers demand greater transparency throughout an aircraft's lifecycle. Digital validation also supports more consistent decision-making across geographically dispersed MRO facilities, helping organisations standardise processes while retaining the expertise of experienced engineers. Looking across the exhibition halls at Farnborough this week, Anderson expects discussions around digital manufacturing, artificial intelligence and connected aerospace to dominate many conversations. He believes validation deserves to be part of that discussion.
"The industry has invested heavily in generating data," he said. "The next phase is making that data genuinely useful. Manufacturers that can validate information faster, maintain complete traceability and make evidence-based engineering decisions will improve turnaround times, strengthen customer confidence and unlock significantly greater productivity."
As aerospace continues its digital transformation, AddQual believes validation is evolving from a quality requirement into a strategic capability—one that could help determine which manufacturers and MRO providers capture the greatest share of a rapidly expanding global aftermarket.
