Re: 737NG Pickle fork issue

It's interesting how some countries and airlines (particularly Korea and Australia) have been very forthcoming with factual data and commentary on the check and repair process, yet its radio silence from many others. Yep. Silence from China. Thousands of high-mile, short-hop 737s operated by low ma...

Your point is good, but your example not so much, alas. I'll admit that USB chargers are possibly not "very expensive", but I'm inclined to think that multiple reports of smoke is a very serious issue, just as serious as reports of cracks.


Fair point.

Re: 737NG Pickle fork issue

Not all ADs are created equal. Some address very serious and very expensive problems, and some address USB chargers

Re: 737NG Pickle fork issue

South Korea is the latest country to ground a number of Boeing 737NG found to have structural cracks, following worldwide inspections of the popular narrowbody. https://www.flightglobal.com/news/articles/south-korea-grounds-13-737ngs-with-structural-cracks-462155/ That is the situation in South Kor...

Re: 737NG Pickle fork issue

Maybe what he’s saying that if you zoom in far enough with an electron microscope you can always find tiny cracks within the crystal structure. But it’s perfectly reasonable to design something well enough that won’t visibly crack in its service life. To imply that literally everything cracks is wro...

Two from lion air. This time both below 22,000 FC. Very bad news for Boeing. They’re all gonna have to get inspected.

Re: 737NG Pickle fork issue

It's currently a team of around 15 or so Boeing AOG support techs working 24x7. There are no part issues anymore. It's just available labor now that is the issue. It is indeed a picklefork replacement (actually dual replacement now since parts are available). Watch the video that was posted earlier...

Re: 737NG Pickle fork issue

This is just not true. These cracks cannot bring down an otherwise serviceable aircraft unless they are allowed to develop much into much more than the inch or so that these ones are - which takes many thousands more cycles. I’m not saying it’s likely. You’re right that it hasn’t happened yet. But ...

Re: 737NG Pickle fork issue

To clarify, you are saying fly till the wing cracks or fly until the pickle fork cracks, because I can see airlines flying the a/c until the fork cracks, it would be no different from flying until a heavy check is due. Good point. An NG with an undiagnosed crack could lose a wing tomorrow. The stri...

Re: 737NG Pickle fork issue

This is a really big job, so highly doubt they would just get changed at next heavy. Parts like these usually only get replaced when an issue is found. I would imagine the inspection cycle on this area will be of a shorter time between inspections. Now if Boeing comes out with a Service Bulletin th...

Re: 737NG Pickle fork issue

[*]There are two follow up questions which are interesting: The first is what would an airline during a heavy inspection after 25,000 cycles if there are no cracks at that time? Is it worth replacing it just in case or running the risk that cracks develop and then the plane is again out for a heavy...

Re: 737NG Pickle fork issue

By now, someone knows about numbers and types affected, the range of flight cycles, likely future ADs and temporary repair vs long term solution to the issue. The last part is pretty important for appraising the value of an airline’s fleet (which airlines borrow against). Boeing may try to make this...
