More KC-46A woes....
“We stand ready to implement any actions as quickly as possible,” Boeing said. “The safety of the KC-46 aircraft and crew is our top priority.”

Lets not forget history.
The A330MRTT was a disaster zone for the first few years. Was on the Projects of Concern.
The boom was lost on 2 occasions. There as a couple of years delay in deliveries, and then more problems.
Airbus worked through these and now the aircraft is reportedly performing well.
This all sounds similar to what the KC-46 is going through now. There seems no doubt Boeing will do what Airbus did, and eventually work the problems out.

I think not.
Yes, Boeing will eventually sort out the problems, but not before they spend an awful lot of money doing so.
Airbus was never in that position.
Cargo restraint issue isn't really a major Boeing design problem , don't know actual detail but normally customer specified as there are lots of different options on cargo systems. So guessing its something new that was not in use before so finding the problems now . Anyone have any info on which company supplies it ?

there have been two significant incidents for the A330MRTT: (from wiki)
1) On 19 January 2011, an air refuelling accident occurred between a boom equipped A330 MRTT and a Portuguese Air Force F-16 over the Atlantic Ocean off the coast of Portugal. Early reports indicate that the boom broke off at the aft end of the boom near the F-16's receptacle which caused the boom to recoil into the underside of the A330 MRTT. The boom then became uncontrollable and oscillated until it broke off the boom assembly at the pivot point. Both aircraft were damaged, but landed safely. The A330 MRTT involved was an Airbus test aircraft destined for the RAAF; the air arm issued a statement that the aircraft was operated by an Airbus crew with no Australian personnel on board. At the time of the incident, Airbus had not begun deliveries.
2: On 10 September 2012 at approximately 19:30 (CEST), an A330 MRTT's refuelling boom became detached in flight at an altitude of 27,000 ft in Spanish airspace. The boom separated cleanly at a mechanical joint and fell to the ground, while the aircraft landed safely in Getafe. There were no injuries caused by the malfunction. The incident was the result of a conflict between the backup boom hoist (fitted to the UAE-destined A330 MRTTs) and the primary boom retraction mechanism, and was attributable to the testing being conducted. Airbus later explained that the malfunction was not possible under ordinary operating conditions, and that procedures had been designed to avoid similar incidents in the future. Following the incident, INTA, the Spanish regulatory authority, issued precautionary restrictions to other users of boom-equipped A330s.
So, the first was part of the development and testing of the platform, the second was again, an Airbus test of new customer requested system see full report here
In neither of these incidents were the aircraft in customer hands.

Not quite look at my post #942 its more for contracting out tanking services simialr to what Omega does. Also speaking to Travis crews at both J-B Andrews and Fairford few months back, they siad KC-10 will not be extinct / on the chopping block once Pegasus starts replacing the 135. Might be way down the line

The U.S. Air Force has identified a potential new design flaw with the KC-46A tanker and banned the fleet from carrying cargo or passengers until a solution is found and delivered. Multiple cargo locks embedded in the floor of the aircraft released inadvertently during a recent operational test and evaluation flight, according to a statement by Air Mobility Command (AMC). Air Force and Boeing officials are working to identify a solution to the problem, AMC says.

The company believes the cargo restraints, manufactured by Ancara Cargo, are well made and designed, but interact in an unexpected way with the track on the aircraft deck. It is considering a secondary lock to hold the first lock in place, but it is concerned an additional mechanism might slow loading and unloading speeds. Each pallet is clamped to the cargo floor via four restraints – one on each side.
As Boeing looks for a solution to the KC-46As cargo lock problem, General Arnold Bunch, commander of the US Air Force Materiel Command, says the last tanker the service received was free of foreign object debris (FOD). The service previously criticized the company’s “culture” for allowing aircraft to be delivered with tools, rubbish and left-over parts such as loose nuts inside the airframe.
Boeing KC-46A programme director James Burgess says culture issues stemmed from letting its best practices lapse, such as requiring tool check in and check out. “We've made a bunch of improvements in terms of our procedures, training, adherence to existing procedures,” he says. “We've really put an emphasis all the way through the production system around cleaning as you go.”

Hopefully a sign that Boeing is taking it's culture issues seriously...good culture costs money, but they're finding that bad culture costs even more!

Such fundamental issues really are scraping far, far below the bottom of the barrel - for an aircraft manufacturer this is just beyond bizarre......

Air Force Says It Will Be Years Before Boeing's Faulty New Tankers Are Fully Operational
Problems with the boom operator's vision system and the boom itself persist and a recently disclosed issue prevents the aircraft from carrying cargo.

The U.S. Air Force has admitted that it will not be able to deploy its new KC-46A Pegasus aerial refueling tankers on operational missions for at least another three to four years, due to persistent technical and quality control problems. This comes as the service continues to take delivery of the aircraft, which have hundreds of issues still left to fix, and that appear to have extremely limited utility in the interim. The mounting delays could have cascading impacts on its plans to retire older KC-135 and KC-10 tankers in the coming years.
