"CFM is reviewing the documentation turned over by AOG Technics as part of our effort to determine the full extent of their sale of parts with fraudulent documentation," CFM said.
AOG Technics could not be reached for comment.
The CFM56 is the most sold jet engine in history and was developed by a transatlantic venture that turns 50 next year.
The findings cover thousands of parts for the CFM56 engine as well as hundreds of parts for GE's CF6 engines, used mainly on commercial freighters.
CFM56 engines entered service in 1982 and power the previous generation of Boeing (BA.N) 737s and about half the previous generation of Airbus (AIR.PA) A320s.
