What A Retired Boeing 737's Engines Are Actually Worth

A retired Boeing 737NG is worth more in pieces than as a complete aircraft. The two CFM56-7B engines under its wings carry half-life maintenance values of $3.8 to 7.1 million each, according to IBA Group data, meaning the engines alone can be worth $7.6 to 14.2 million combined. Aviation valuation expert Rob Mikus demonstrated that once engines, landing gear, and avionics are removed from a 737, the airframe has "almost no value." Companies like FTAI Aviation, which owns more than 450 CFM56 engines, have built entire business models around that gap.
