Unum Aircraft Seating (Unum) has begun its second Technical Standard Order (TSO) application, for the Unum One family of lie-flat business-class seats, which is an important step in the process of making the seats officially ready for installation.
Mark Hacker, chief technical officer at Unum, said of this latest stage on the process: “Together with our [Part 21J] CAA Alternative Procedures to Design Organisation Approval (ADOA) and our Part 21G Production Organisation Approval (POA), taking this next TSO step strengthens our ability to meet airline needs amidst current sector capacity challenges.
“It’s going to be another big year for Unum. Our certified business-class seats have been awarded design accolades, and with our manufacturing base at London Gatwick, we are ready for widebody and single-aisle customer programmes and have delivery slots available for early 2026.”
Unum’s first TSO application was a key part of Unum’s ADOA approval achieved earlier in this year, which was followed by a successful CAA-witnessed certification test campaign, validating Unum’s design and certification processes. The approval demonstrated Unum’s ability to meet critical certification requirements, which the company says affirms its capacity to manage design, apply for certification, and manufacture seats in-house efficiently and effectively.
With the second TSO approval underway, Unum will continue its dynamic testing campaign, supporting the installation of its product family across multiple aircraft types.
This announcement follows last month’s news that Unum Aircraft Seating, raised additional funding to support research and development, and to expand Unum’s sales pipeline within the airline industry.
