Boeing has resolved its issue with leaky KC-46A Pegasus aerial refuelling tanker fuel systems, according to a company spokesman.

Boeing spokesman Larry Chambers said on 14 September during the Air Force Association’s (AFA’s) annual conference that there are no more remaining KC-46As with leaky fuel systems. The US Air Force (USAF) announced in June that 18 KC-46As had problematic fuel systems and that the issue was being upgraded to the service’s most serious deficiency: Category 1.

Boeing on 2 April cited faulty ‘U Cup’ seals for the leaky fuel system as these seals were particularly difficult to install. They were also more sensitive to Boeing’s installation technique than originally thought.
