"Potentially, that means between 48 and 96 aircraft being taken out of service whilst airlines arrange for the parts to be removed," Reeve added. They asked the High Court on Tuesday to order AOG and Zamora Yrala to preserve relevant documents and to disclose sales documents relating to CF6 and CFM56 engines since February 2015. "Everybody now knows that AOG parts are not necessarily to be taken to be the claimants' parts," he said. The CFM56 jet engine powers the previous generation of Boeing 737s and about half of the previous generation of Airbus A320s. Britain's Civil Aviation Authority said in August it was "investigating the supply of a large number of suspect unapproved parts" through London-based AOG Technics.
