Honeywell received FAA certification for its first 3D printed flight-critical engine component

Honeywell Aerospace, the aerospace division of conglomerate Honeywell, has received a Federal Aviation Administration (FAA) certification for its first 3D printed flight-critical engine component. The part in question – a #4/5 bearing housing – is a key structural component of the ATF3-6 turbofan engine found in the Dassault Falcon 20G maritime patrol aircraft. The part is already in production and has been installed in an operational Falcon unit, with dozens more expected to be printed by the end of the year.

Jon Hobgood, Vice President of Manufacturing Engineering at Honeywell Aerospace, states: “This is a major milestone for Honeywell because it demonstrates the maturity of our Additive Manufacturing operations and paves the way for us to print more certified, flight-critical parts in the future. It also is a major win for the additive industry, as flight-critical parts face heavy scrutiny and high standards for qualification and installation on aircraft, but this shows it can be done.”
