KC-46A testing glitches could delay USAF tanker milestone
flightglobal | September 19, 2017
Despite earlier assurances that Boeing would deliver the US Air Force's first 767-based KC-46A tanker by the end of this year, boom scraping issues and a slew of uncompleted test points may delay delivery until 2018, the head of its Air Mobility Command has revealed. More than half way into testing, the USAF has discovered severe flaws on the tanker, known as “category 1 deficiencies”. Among the most glaring, the tip of its boom has on occasion struck receiver aircraft outside their refuelling slipways.
