Fuel Leaks Are Latest Problem for Boeing’s Troubled KC-46 Tanker

In addition to existing serious problems, including the Remote Vision System used to monitor refueling operations, the US Air Force has now upgraded to Category I deficiency the fuel leaks it had previously found in the Boeing KC-46A tanker. (USAF photo)

Boeing's seemingly perpetually troubled KC-46A Pegasus tanker has yet another major problem, its fuel system leaks excessively. This comes nearly a month after the U.S. Air Force made clear that it would not use its existing examples for aerial refueling, their core mission set, except in an absolute emergency.

This was due to already serious existing issues, especially with the complex Remote Vision System that boom operators use to see what's going on at the back of the aircraft while linking up with receiving aircraft.

The Air Force announced that it had defined the KC-46A's fuel system leaks as a so-called "Category I" deficiency on Mar. 30, 2020. Category I issues are problems that would prevent the aircraft from performing one or more primary missions. The service also said that it had first become aware of the leaking in July 2019 during a test, but had initially categorized it as a less severe issue.

"The Air Force and Boeing are working together to determine the root cause and implement corrective actions," according to an Air Force statement. "The KC-46 Program Office continues to monitor the entire KC-46 fleet and is enhancing acceptance testing of the fuel system to identify potential leaks at the factory where they can be repaired prior to delivery."

The Oryx Handbook of Iranian Drones

Image
The goal of this list is to comprehensively catalogue Iran's past and current inventory of unmanned aerial vehicles (UAVs) and their armament. In an effort to streamline the list and avoid unnecessary confusion, this list only includes military drones associated with Iran's defence industry or military-grade UAVs with at least some chance of entering service. Notes:  - If several configurations of a drone with one designation are known, they are added as such.  - The part within the apostrophes refers to other designations or an unofficial designation. -  UAVs that did not enter service or have yet to enter service have been placed in the prototype category. - When a type is dual-capable, it is added in both respective categories. - Dubious claims are referred to as ''claimed to be capable''. - Although several types of Iranian UAVs have been sighted in Syria and Iraq, the foreign service section of this handbook only includes those confirmed to be in s
