Like other French companies, Lisi Aerospace suffers the consequences of the temporary halt of production of the Boeing 737 MAX. Indeed, Lisi Aerospace supplies the fasteners for the Boeing 737 MAX and produces critical parts for the CFM Leap-1B which powers the aircraft and that Safran decided to reduce the production rates.

Although, Lisi Aerospace just escape the critical situation with a contract signed by MTU Aero Engines enabling the French company to diversify its portfolio of activities in the airliner engine segment since it relates to the supply of high pressure compressor blades for Pratt & Whitney's GTF engines. The multiple variants of Pratt & Whitney GTF power the Airbus A220 as well as the A320neo and Embraer E2 families. The ten-year contract covers the supply of more than one million parts. The blades will be produced entirely in France at the Lisi Aerospace sites in Chaumont (Haute Marne), which will start operating in 2023, and in Parthenay (Deux Sèvres), which “has recently been expanded to accommodate new commercial developments”. Here, the high pressure compressor blades for Pratt & Whitney GTFs. In addition to this product diversification, the company headed by Emmanuel Viellard can deploy its manufacturing capacities with compressor blades. The culmination of two years of joint work with MTU Aero Engines.
