On the 3rd of October an airworthiness directive was sent out from the FAA regarding cracks found in a component known as a "pickle fork" in a few Boeing 737NG aircraft that were being rebuilt from passenger aircraft into Freighter-aircraft.
What does this actually mean? Is it dangerous and what is a "pickle fork" anyway?
These are some of the questions that I will tackle in todays "Mentour Special".

Thank you so much for your videos. I have some questions:From where do you have all this inside information? What is your motivation to do all of these videos? Are there people in the industry who might be mad at you since you release knowledge and information from your industry?

As someone who works in the industry, I believe that he is just talking to somebody in his engineering department(and his company is huge, I've seen how they worked 10 years ago, and I am impressed by Ryanair Engineering,they know what they afe doing, and I have seen how LHT works because we have worked with them in Croatia, they are not far behind at all) because his information is spot on. If anything, industry is happy to share information to avoid hysteria that has been created about flying and safety of flight. We need guys like him, and as someone who works in engineering, I have learned more about pilot's job from him than I have ever learned from pilots I work/have worked with.

While I agree that typical American business practices have hurt Boeing's rep, let's not forget this:
Airbus had several crashes that were caused by non-functional pitot tubes, and these planes were not grounded as the 737 Max. People died, no grounding. Why?

He must work for Boeing. Problems with the NG manufacturing process and faulty parts were known by Boeing, the FAA and the Federal Government. There were investigations at that time which showed sourced items out which include what's talked about here and others being out of spec but employees were told to use them anyway, sometimes having to beat them with a hammer or drilling new holes to get them to fit. Now they seem to want to make us believe they are as surprised as we are when everyone involved knew about it would happen even before the plans were built. Classic cover up of money over humana lives.

With everyone making airplanes profits are low..
Boeing will move to Space Exploration where profits are huge due to there is no EPA in space
When you walk around the Everett plant everything is geared to Space Exploration!
And yes Boeing has turned into a financial business.
When these developing countries take money from the World Bank they have to buy planes construction equipment from American companies..
Boeing Airplanes Components are made around the world!
There was a huge problem with landing gears made in Vietnam.
And with turban shafts made outside of the States...
I'm really thinking Boeing will be getting out of the airplane business to continue on in space where you don't need thousands of employees to put airplanes together!
There is a tremendous space company's looking for investment in the space industry.
Good return on investments as long as the space company is located in Texas!

If it's an issue with the aluminium alloy used then it will be fully traceable all the way back to which hole in the ground it came out of and all steps in between. Sometimes at work when we have 2 different batches of the same material (and each clearly labeled ) it is necessary to have the policy of Not in the same building at the same time !

These parts are probably machined from extruded aluminum alloy and if not extruded correctly, soft spots can exist. One solution would be to require hardness testing on the ends and the middle of the parts in several locations. Another factor could be after machining; if not machined properly, warped conditions might exist and - even if not permitted - some supplier might "straighten" the parts (even after penetrant inspection) to point of inducing too much stress and even cracks...there are companies making parts that do not follow the manufacturing specifications.

A fault in the manufacturing process has got nothing to do with mounting, torque too high etc.... this refers to assembling process. To me it is an issue of manufacturing process but by saying that I am suggesting the cracks could be due to inadequate temperatures during closed die forging, also inadequate amounts od deoxidisers in the ingot or simply low quality metals used in the production. In other words Boeing is cutting corners because profits are more important to them than our lives. Boeing should ground all of its 737 fleets all across the world for NDT checks because if there are 1 inch + craks on the surface or sub-surface then I can only wonder what is going on the inside. And with the streesses of the payload during the take off or turbulences it is not a matter of if but when. God bless and good luck with that Boeing.

In 1978 I worked for an airline as a mech. During a D check on a 727 200 we found one of the wing spars had not just cracked but also separated and a small gap between both edges had worn smooth over the time the crack was there. The integrity of the wing still held due to the way it is built, A monocoque construction held that wing together with untold landings and take-offs.
Result of an extremely heavy landing.

Boeing do as they always do. Makes a plane, then sit back and wait until one crash. Then they make a fix and try again, wait for the crash fix it and this is how they use to work. The cost in human life stacks up.

Time to get a rating for flying Airbus? Boeing seems that have forgotten how to make a 60 year old airplane... and seem to suck at making new ones. I really wish Boeing well but their high dependance on out sourcing their manufacturing is coming back to haunt them. They seem to be a shell of their previous selves. If many of the 737 NGs are grounded, Boeing's ability to survive is in the balance.

I'm not sure about the terminology at Boeing, but as a design engineer at a transportation manufacturing company I can tell you that the term "Fail Safe" does not refer to what you suggested.
Fail Safe means that the part/system fails in a safe mode. For example, if you have a vehicle with airbrakes they are designed to apply the park brake if you lose air pressure. What you described is system redundancy or backup.

DC-10 isn't flying much anymore and the engine fell of because maintenance put it back on incorrect.
This Boeing structural problem is a manufacturing issue.
Boeing 737NG structural problems were predicted a couple years ago due to substandard assembly.

Hrvoje Mičuga (1 month ago)
As someone who have evaluated this AD and ordered inspections, I can say that Mentour has done magnificient job explaining this. There is just one small mistake, for aircraft with utilization higher than 22600 FC limit is 1000 FC from the AD effective date(not a year as he said). Both Boeing and FAA have done great job here. Inspection itself is easy, access is a problem. Lower than 30000 FC - before reaching 30000 FC or within seven days whichever occurs later. With utilization lower than 22600 FC, within 1000 FC or before 22600 FC, whivhever occurs later, anything in between: 1000 FC. Utilization higher than 30000 FC - within 7 days(up to 10.10.2019.)
Hrvoje Mičuga (9 days ago)
Dear Steve,just an update for you, a NPRM(FAA equivalent to PAD by EASA) has been issued for parts mentioned in AlJazeera documentary(it seems this is the case), and pickle fork inspection has been expanded to include additional 6 fasteners. Company I work for did not have findings on pickle forks, I hope it will stay that way, and for bear straps, proposed threshold gives me an idea it is treated as not so urgent issue(they will give us 6000 FC to inspect it, which depedning on average sector length can last from 2 years for a company that has a lot of short flights to almost 5 years for example in case of company I work for). What I am trying to say is that immediate grounding will not happen like it did with some aircraft affected by pickle fork cracks, operators will do the bear straps inspection during next C-Check. Again, it is properly managed by Boeing and FAA.
Steve DMR (30 days ago)
"Both Boeing and FAA have done great job here" >> Stop being naive. This is simply the result of the FBI giving direct notice to the FAA regarding faulty fabrication parts, as pointed out (again) by the various whistle blowers during recent FBI's interrogations, as part of their ongoing criminal investigation into Boeing. The notion about these faulty parts has been leaked by these whistle blowers since 2002!! So it's rather long overdue by the FAA and Boeing, instead of 'great job'. Btw, only someone with suicidal tendencies would ever fly a Boeing aircraft again.

I doubt that the cost would be justified. Then that said, the wing box is probably a separate (allthough well attached) part to the round fuselage, so I guess that technically it could be replaced. Sounds very expensive though. Especially on an older plane.
