US Grounds all F-35s for fuel line failure

Thu Oct 11, 2018 2:49 pm

per https://www.bbc.com/news/world-us-canada-45827795 the US military has grounded all F-35s after an analysis of the earlier crash.. the article also mentions undefined "other issues" (quotes mine because no specifics were given)

The stand down affects more than 200 jets while an "inspection of a fuel tube" in F-35 engines takes place, according to a Pentagon spokesman. “If suspect fuel tubes are installed, the part will be removed and replaced. If known good fuel tubes are already installed, then those aircraft will be returned to flight status. Inspections are expected to be completed within the next 24 to 48 hours,” Joe DellaVedova, a spokesman for the F-35 program

Unfortunate but standard practise when a faulty part enters the supply chain. Sounds like the part is not in a difficult place to access so shouldn't be long before the fleet is back up again. Would be interested to know what the estimate is on the number of faulty fuel tubes in the fleet.

Looks like not all F-35s have been grounded as the UK are continuing to operate the Bee from QE.

Contrary to reports, all F-35 jets have not been grounded. We have paused some F-35 flying as a precautionary measure while we consider the findings of an ongoing enquiry. Flight trials from @HMSQnlz continue and the programme remains on schedule #F35 @thef35

The fault that caused the problem is the easy part. The fault that allowed the defective part is harder. Somebody not only made a bad tube, they probably ignored steps or falsified documentation that should have insured such parts wouldn't make it through. This kind of crap is what makes the U.S.A.F. the worst micromanager in the universe in the first place.

The US Air Force produces exactly ZERO of ANY parts in the F-35.

I was obviously talking about the contractor who makes it, and you're wrong in any case. The maintenance depots often fabricate low tech parts since Lockheed isn't the kind of company you can call to pull a part out of an assembly line bin. They've even started 3D printing some, which you'd know if you bothered reading the news thread.

A risk-balanced approach to keep the QE timeline on track?

All Norwegian F-35 is back in the air after only half a day of inspection.

We are talking about a faulty design in a fuel part. I was 100% correct in regards to the topic - The Air Force designed exactly ZERO of the F-35 parts. 3D printing parts is producing the part after the fact, for which they had no hand in the design or testing of such part. As far as the news goes, I'm up to date (very much)...I just don't twist what I'm discussing to meet my needs vs. what the thread is actually discussing.
