A lawsuit against a UK supplier by CFM International says 68 jet engines were found to be fitted with “falsely documented” parts. 

Central to the UK lawsuit, filed on September 7, 2023, by the joint venture of General Electric and Safran SA against AOG Technics, is to establish more information about the potential fake components.  

“Safety is our first priority, and we are taking aggressive legal action against AOG Technics to accelerate the industry’s ability to identify parts sold by this third-party with falsified documentation,” a CFM spokesperson said in a statement. 

In August 2023, the European Union Aviation Safety Agency (EASA) advised aircraft owners, operators, maintenance organizations, and distributors to inspect their records to “determine whether aircraft or engine parts have been obtained from AOG Technics, either directly or indirectly”. 

In a report by Bloomberg on August 31, 2023, the publication said that regulators had found that AOG had supplied parts for CFM56 engines, used in older-generation Airbus SE A320 and Boeing 737 planes. 

No incidents have so far been linked to falsely certified parts and CFM is not affiliated with AOG.  

According to Fortune, the EASA advised that components involved included turbine blades.  

“We remain fully engaged with aviation regulatory authorities to support their investigations into AOG Technics, and we continue to work with our customers to assess the authenticity of documentation for parts they acquired directly or indirectly from AOG Technics,” the CFM spokesperson said.
