McConnell AFB team member creates innovative solution to persistent problem

A McConnell Air Force Base Innovation Lab initiative led to the creation of a 3D-printed funnel that improves KC-46A Pegasus engine servicing. The innovation, developed by Tech. Sgt. Brandon Branstetter, reduces oil spillage and saves the Air Force procurement time and money by utilizing durable, fuel-resistant thermoplastic polyurethane.<br /> <img alt="A thermoplastic polyurethane (TPU) fuel funnel is used to service an engine starter at McConnell Air Force Base, Kansas, 17 July, 2026.
