From Scandal to Solution: Existing Tools that Could Have Stopped a Counterfeit Spare Parts Fraud
Aramid Technologies, the creator of SmartCert and a leader in aerospace quality assurance, offers a summary and insight related to the recent counterfeit aircraft parts scandal involving London, UK-based AOG Technics. The European Union Aviation Safety Agency (EASA) and Federal Aviation Administration (FAA) have confirmed that UK-based AOG Technics distributed parts for one of the most widely used commercial aircraft engines, falsely certifying they were manufactured by Safran and General Electric (GE). In July a maintenance shop flagged suspicious parts that looked to have been previously used, but were accompanied by Author- ized Release Certificates (ARCs) indicating they were new.

Fastener Failure Caused by Galling
Galling is an adhesive “cold-welding” process that occurs between two metal surfaces that are moving across each other under high pressure. Galling often occurs during the torqueing or tightening of stainless steel fittings where the shear forces between the threads cause transfer of materials and subsequent hardening between the bolt and fastener.
