Cargo lock issue on KC-46A - influence on B767F?

Fri Sep 13, 2019 9:54 am

FlightGlobal is reporting an issue with the KC-46A cargo pallet locking system, categorized by the USAF as "Category 1".

I´m not familiar with this system, is it an off-the-shelf system used on the 767F as well, or was it specifically developed for the KC-46A? If the former, will it have any influence on the 767F operating?

Anyone able to sheet some light on this?

Clearly not the best days for Boeing currently, too many issues coming up at the same time.

The US Air Force (USAF) has banned the Boeing KC-46A Pegasus in-flight refueling tanker from carrying passengers and cargo after it discovered cargo floor restraint devices unlocking during a recent operational test and evaluation flight.

“During several KC-46 test flights in which cargo was being transported, multiple cargo floor restraint locks malfunctioned and came unlocked. Prior to departing for each of these missions, aircrew fully installed, locked and thoroughly inspected each restraint, and performed routine inspections of the restraints in flight,” says the USAF. “Despite these safety measures, the unlocking of cargo floor restraints occurred during flight, although no cargo or equipment moved and there was no specific risk to the aircraft or crew.”

So what kind of Pallet locks did Boei g come up with? Some new Wingo-Dingo Pallet lock? What happened to the old 9G locks in the 777and 767 cargo bays? That lock is easy to repair and replace and can be replaced in a few minutes. YgbSM!

Military configurations are not the same as what is used in civil cargo carriage. Carriers like FX and UPS have their own lock systems installed on these planes and there have been no problems reported. This will be another issue for the USAF and Boeing to work through.

Quick way to lose an airframe and crew. Something so basic to the cargo industry can't be adapted. SMH.
I don't understand everything I don't know about this.

Is this one of those instances where the government insists they have to mil-spec every single thing just to keep some useless program officers in the Pentagon employed, only to have it blow up in their faces like with the coffee mugs? It is not like cargo locks are a new thing, they have been around for a long time and they generally just work, why did the military have to go with their own versions? Compatibility issues with the military airlift fleet?
Read this very carefully, I shall write this only once!

Nobody even mentionef the people that went to jail. ....but really, that is off topic.

The bottom line is that this is yet another setback for Boeing.

As yet unknown... but quite possible: It may be that the US Military has a specific cargo lock-down device (or several approved ones) and Boeing used the one they were specified to use or one of the approved ones,,, and then they failed in real world testing on the KC-46. It would not be the 1st case of that happening...

I doubt that Boeing engineered or purchased something just for the KC-46. I suspect that they purchased already existing and "approved" hardware.

While at least a minor glitch problem for Boeing. It might not actually be their problem.

Have a great day,

Thanks for answering the question.
