The deal, which is expected to be announced Thursday, is not finalized. As such, there is a chance it will not go through.
One outstanding issue yet to be resolved is how to carve Avio's space business out of the acquisition. Avio, 81 percent of which is owned by the private equity firm Cinven, makes both commercial and military jet engines and propulsion systems for satellites. But GE is not seeking to buy the space operations end of Avio's business, the Journal said.
GE is already responsible for about two-thirds of Avio's contracts, which explains why GE is interested in the purchase.
GE is expecting a large increase in jet engine orders in the next five years and is working to ensure it has an uninterrupted supply chain.
Avio employs 5,200 workers and last year had sales of $2.6 billion, a 16 percent increase over 2010.
