The Air Force has barred the new KC-46 tankers — 11 of which are already housed at Wichita’s McConnell Air Force Base — from carrying passengers or cargo after “serious technical issues” discovered during a recent test flight. Cargo locks on the floor of the aircraft became unlocked during a recent flight, the Air Force said in a statement. “As a result of this discovery, the Air Force has submitted a Category 1 deficiency report and is working with Boeing to identify a solution,” Air Force Mobility Command spokesman Col. Damien Pickart said in a statement. “Until we find a viable solution with Boeing to remedy this problem, we can’t jeopardize the safety of our aircrew and this aircraft.” The directive was first reported by Defense News.
