As aerospace manufacturers work to address an industry-wide shortage of experienced maintenance engineers and inspectors, attention has largely focused on recruitment, apprenticeships and training. Yet for Derby-based digital quality specialist AddQual, the greater challenge may be preserving decades of engineering knowledge before it disappears from the factory floor. Recent industry analysis has highlighted the scale of the issue. With a significant proportion of experienced aviation maintenance technicians approaching retirement, manufacturers face not only a shortage of skilled people but also the loss of the judgement, experience and decision-making that underpin safe, repeatable production.
While increasing the number of engineers entering the industry is essential, AddQual believes manufacturers must also consider how critical expertise can be embedded into digital validation processes rather than remaining with individual employees. AddQual provides advanced inspection, traceability and digital validation solutions to aerospace manufacturers and is seeing growing interest in systems that make quality decisions more consistent regardless of who performs the inspection. Ben Anderson, Managing Director of AddQual, believes the conversation should extend beyond workforce numbers.
"Every experienced inspector develops an instinct that comes from years of working with complex aerospace components," he said. "That knowledge is incredibly valuable, but if it only exists in someone's head, manufacturers become vulnerable whenever people retire, change roles or move on. Digital validation allows organisations to capture that expertise, standardise decision making and ensure every inspection follows the same proven process. Instead of relying on one individual's experience, businesses can build that knowledge into their quality systems."
As aircraft production continues to increase and MRO activity grows worldwide, manufacturers are handling greater volumes of inspection data than ever before. Every component generates dimensional measurements, process records, inspection reports and supporting documentation, creating an expanding body of engineering information that can either become a strategic asset or an administrative burden. For many organisations, the challenge is no longer collecting quality data but ensuring it is used consistently to support faster engineering decisions and complete traceability. AddQual's MiDAS platform has been developed to address precisely this challenge, bringing together inspection results, validation workflows and engineering rules within a single digital environment. Rather than simply recording inspection outcomes, the platform enables organisations to create repeatable validation processes that reflect established engineering knowledge.
Anderson believes this shift will become increasingly important as experienced engineers leave the industry.
"The manufacturers that adapt most successfully won't simply recruit more people," he said. "Instead they'll create systems that help new engineers become productive more quickly by giving them access to structured processes, validated data and consistent decision logic. Digital technology isn't replacing engineering expertise; it's preserving it. The goal is to ensure the experience built over decades continues to support production long into the future."
The wider aerospace industry has already embraced digital manufacturing across machining, automation and production planning. AddQual believes validation now represents the next stage of that transformation. As qualification programmes become more demanding and customers require greater levels of evidence and traceability, organisations that can combine experienced engineering judgement with intelligent digital validation will be better positioned to improve quality, reduce variation and accelerate production. For AddQual, the future of aerospace manufacturing lies not only in attracting the next generation of engineers but in ensuring the expertise of today's specialists becomes a permanent part of tomorrow's production systems.
