Reporting for AviTrader’s MRO 360 Magazine, David Dundas spoke to Nigel Bedford, Technical Director at AJW Group, about AJW’s approach to USM airworthiness.

Asked about regulations currently governing the use of used serviceable aircraft material, Bedford said that “Since Brexit, the UK CAA has also established its own framework, which is closely aligned. In practice, most operators and MROs look for dual-release certification, an FAA Form 8130-3 or an EASA Form 1, to ensure material can move seamlessly across borders.”

Continuing, he states that global standards from ICAO and accreditations like ASA-100 or AS9100 play a big role in setting the benchmark for safe use of USM. 

When it comes to certifying that a used part is safe to return to service, Bedford shares that when a part enters AJW’s MRO facility, AJW Technique, it goes through a structured process to ensure it is fully compliant and safe to return to operation.

“Our engineers and technicians start by performing a detailed incoming inspection and conformity check, followed by evaluation against the Component Maintenance Manual,” shares the AJW Group Technical Director. “Depending on the component, non-destructive testing and functional checks may also be carried out, and any required restoration work is done strictly to approved data.”

The risks of counterfeit parts came into the limelight last year with the criminal case involving AOG Technics – the worst example in recent years of counterfeit USM. How do businesses verity the authenticity and origin of USM?  

Bedford acknowledges that “counterfeit parts are one of the biggest risks to aviation safety, which is why AJW put so much focus on getting it right.”

Giving an insight into AJW’s process, he shares that it USM verification starts with the paperwork. “We check certificates of conformity, maintenance history and, where required, back-to-birth records for life-limited parts. Just as important is who we buy from, so we only source through trusted, approved suppliers with the right industry accreditations.”

Bedford adds that AJW Group carry out physical checks on markings and serial numbers and are use digital tools and track-and-trace technology to give its customers complete confidence in the origin of a component.   

Traceability is vital, and AJW keep meticulous digital records covering operational history, service bulletins, airworthiness directives, and any modifications. 

“For life-limited and other critical components, we also maintain back-to-birth traceability as a matter of course,” says Bedford.  

What do buyers have to consider when sourcing used serviceable material?   

“For buyers, the first question is always whether the certification provided will be accepted in the jurisdictions where the aircraft operates.” 

It’s also crucial to assess the part’s condition, whether removed, serviceable, or overhauled, as this affects cost, reliability, and turnaround time. Buyers should also weigh factors like warranty, insurance, and supplier credibility.   

Ultimately, “sourcing USM is about striking the right balance between safety, compliance, lead-times, and cost efficiency,” Bedford concludes.
