Airplane Disaster Cover-Up? The Conspiracy That Shook the Aviation Industry! | Mayday: Air Disaster

[@fifiladu2659]

I am so always so impressed with the ability of these investigators to keep drilling down with such incredible determination through such intricate amounts of evidence to finally pinpoint the actual accident causation. Likewise, I am impressed with this channel’s ability to share the crash information in such detail, while still maintaining great respect for the accident victims and their families.

[@scottbuske3920]

I was a jurist at a trial over bogus bearings on airline generators in the early 90's. The generator was not a critical piece of equipment. It caused lights and airflow in the cabin to fail. Two defendants. One had 25 charges, the other had 26. The separate charge was lying to the FAA. We hung on every charge but that one. The bearings in question were still in the original boxes in the stock room. The bearings were purchased at a local distributor. The manager lied to the FAA about his knowledge of them. the other defendant was a machinist who tested the units. His problem was the testing machine did not go as high as required to pass the units. But it was all he had to work with. Of course we didn't know this at the time, but there had been several/many convictions on higher up people who knew, okayed, and insisted on the use of these bearings. Including the president of the company. Google Skyway Airlines, Rockford IL. Berry Bearings

Worse yet, being so close to Rock Island I bet that company has sold bearings for military aircraft too.

The jack screw was a known single point of failure, and the airline wasn’t following inspection intervals so the threading being stripped was not discovered. Listening to the crew struggles was heart wrenching as they didn’t have a chance.

[@michaelmartinez1345]

@tiffinyanderson4403 , Some things you mentioned were spot-on, like the airline (Alaska Airlines) the flight # (261) and the year (2000)... The date was 01/31/2000 @16:21... The main causes of that accident were 1)Overly aggressive production managers on the repair facility floors 2) Extended routine check intervals, requested by Alaska maintenance management, and granted by the FAA 3)Mechanics, who were tasked to perform these routine checks, who were "pencil ✏️ whipping' the procedures (signing, but NOT actually doing) the checklists... 4)An Inspector - finding problems with the stab-trim jackscrew and follower nut that adjusts the horiz stab trim being too far out - of the wear limits. 5)Upper management telling that inspector to take several weeks of paid time-off... 6) Upper management pressuring the floor production managers to delete the computer entry of what that inspector found, and destroyed the hand-written non-routine document that was generated by that inspector grounding that aircraft, until the horizontal stab trim actuator is replaced.... 7)The production managers kicking the tires and lighting the fires to get that plane flying again... Complete with the illegally worn horiz. stab. trim actuator 8) The Alaska Airlines SMC (Station Maint. Controller) in Seattle instructing the pilots to bypass the now (01/31/2000) problem plane with the inoperative horizontal stab trim, to continue flying past LAX, and to continue to SFO because it would match their schedules better to have it repaired in SFO... That was the last chance and radio transmission, to save the lives of all 88 souls onboard as the plane dove into the ocean nearly vertically going very fast... God bless those souls...

I hope if the root ends up being a widespread industry change, that it helps to solve a lot more of the ongoing worrying problems.

The counterfeit parts problem was minimal until the US normalized relations with China in 1978.

[@voraciousreader3341]

Well, the point was, _there was no regulation on the parts industry in the US until this crash got the FAA onto it!_ People-historically Republicans-are all about “small government,” which translates to little or no regulations. If you don’t believe me, look up Ronald Reagan’s deregulation activity and you’ll see what I mean. The problem with the conservative and libertarian view is that citizens are expected to trust that people will regulate themselves with no need of governmental oversight, but it’s precisely the untrustworthiness of unscrupulous people who are only interested in making profits from the unwary which requires governmental oversight. And, with the very high level of sociopaths and psychopaths in our country, some say as many as 20 per 100 people, shows that it’s probably people without consciences who are the ones who rig the system in such a clever way that they don’t get caught.

Looking at the bolts it's fairly obvious that 3 are bogus. Aircraft bolts are bored through at the end for safety wiring. This wire will not allow the nut to come off the bolt. Only one of the bolts shown had that hole. The material code on the head tells the rest of the story.

[@michaelmartinez1345]

@bills6116 Some of the fasteners have drilled wrenching heads , some special applications use other methods to secure the wrenching heads, like tab washers...Some threaded fasteners have a hole drilled through the center of the threaded shank, for using a cotter pin and a castleated nut, while other applications use different methods to safety the hardware from vibration loosening them... Again, it depends on the application... The aircraft IPC can then be referenced for the correct parts to be used in those specific applications... The markings on the head of the bolts used on aircraft, usually do NOT tell what their tensile strength is, like what they do in the automotive / trucking industries... The aircraft hardware can be very specific & specialised, and critical parts are often given an authenticity certificate , which is submitted with the paperwork for that specific job... These critical structural parts can also be serialised and extremely expensive, which attracted the unscrupulous counterfeit aircraft parts suppliers like 🧲 Magnets to Iron ....

It is possible to tell differences in hardened steel or heat tempered bolts compared to mass produced hardware bolts and nuts. I experienced this in building racing engines needing hardened steel bolts for rod and crankshaft bolts. Bolting moving engine parts together. Modifying an engine to turn 10,000 to 12,000 rpms compared to factory rpms of 5,000 to 6,500 rpms requires stronger bolts. I paid a shady character dude to rebuild the bottom end of a racing engine that came apart and blew up the first race. Upon inspection, we found he used standard hardware bolts purchased in any hardware store for 50 to 60 cents each, whereas the racing bolts for the higher rpms were approximately 8 to 10 dollars each. (sold in packs of 16 for an average of $130.00 per set). I could easily tell the difference.

[@Zach-td5mb]

ARP hardware is always worth the price

[@davelowets]

One can also FEEL the difference between hardware store bulk bolts and an ARP fastener in their hands. But when it comes to counterfeiting a product, the manufacturers of the fake products can, and will, emulate the look and feel of their fake products enough so that you can NOT tell by look or feel only. Hardware store bolts are NOT designed to copy the look or feel of proper hardened bolts, BUT the counterfeit ones ARE. That is why it took a metalurgist to find out the truth. The ones making the counterfeit bolts were NOT simply going to the hardware store and buying generic bulk bolts and trying to pass them off as originals.

Exceptionally well done thank you

[@richardkeilig4062]

Terrible situation. God bless these people.

[@MartinChadwick-xe7gh]

I guess it has also meant that manufacturers have been able to charge outrageous prices for genuine parts. So not entirely a win win situation. Though, sometimes for instance car engine bolts are tightened till they have just started to yield in which case they should not be used again. So using unknown origin bolts would be particularly risky.

[@davelowets]

T.T.Y. engine bolts are pretty much a standard these days.

[@deplorabledave1048]

Interesting and fascinating story. I listen to the entire video

[@jkaugust3586]

This video suggests that bogus counterfeit parts are history; they are not. Just this past year the US AirForce grounded its stratoliner tankers over vertical stabilizers with bogus parts. As long as there are unscrupulous people in supply chains, they will be bought. Over my 50 year engineering career I've seen them in every commercial power application - nuclear, fossil and combined cycle. Rigeur and dealing only with dealers of integrity prevents them from being installed. Virtually all purveyors I've seen have never been taken to task.

I’m amazed they seem to find almost all of aircraft’s that get into trouble. It’s admirable how committed the team involved in an investigation. Right down to the people finding parts and pieces. I know flight crews have recurrent training yearly. I truly hope they are doing the same for the mechanics. It’s normally done to combat complacency that must be part of the reason for these horrible mechanically related decisions made many times on this aircraft. Everything done mechanically an aircraft are recorded cradle to grave. Imagine being a mechanic knowing your work was part of the reason lives were lost. Imagine knowing the company you work cuts corners on parts and someday these parts could be why people have died.

What "horrible mechanically related decisions made many times on this aircraft?" Watch the video again, without prejudice this time.

[@steven7385]

The turbine engines that power the propellers function identically to a jet engine. Still, you wouldn't call such an aircraft a jet.

[@steven7385]

The APU is also a turbine.

[@pensivelyrebelling]

These pilots were so dedicated to ensuring their passengers got to where they were going. They went to great lengths to ensure that plane took off for them and (whether they meant to or not) protect the airline’s reputation. They are exactly the kind of employees any company would want. Perhaps less caring employees would have let the flight be grounded and saved everyone’s life. What a terrible, ironic dichotomy. ETA: there seems to be a lot of misunderstanding about the point I’m making here. This isn’t about blaming the pilots. It’s simply pointing out the *irony* that they were so dedicated and there were points that if they hadn’t been, the flight might not have taken off and the lives would have been saved. That’s not blaming the pilots. They did nothing wrong. They couldn’t have known they were flying a doomed plane. How many crash investigations have you seen where pilot performance WAS and issue? How many times have you seen good pilots go this far out of their way to get their passengers where they’re going? It’s tragic irony but irony nonetheless. It’s an observation and nothing more.

[@Pbairsoftman]

Blaming them is absolutely ridiculous, normally the APU being run in flight is perfectly safe if unorthodox. The airline and system failed THEM

​@@pensivelyrebellingmaybe they thought the post was sarcasm... butnagree with you.

[@michaelmartinez1345]

@pensivelyrebelling , To a point, yes... That makes good sense... But to what extent should the aircraft be allowed to continue to fly, in that condition? I remember working at a major U.S. airline, and other aircraft maintenance facilities , where policies were determined for each aircraft type, known as the MEL and CDL lists... They are still probably being used to this day... The M.E.L. are the Minimum Equipment Lists... The C.D.L. are the Configuration Deviation Lists... They gave the pilots a basic guideline of what IS, and IS NOT acceptable for safe flight... The Mechanics (Technicians) who assigned those inoperative systems a deferment to temporarily operate in this manner had to make an aircraft logbook entry and put a deferment tag (placard) on the circuit breaker /control device of the affected system. The technician also had to generate a notice on the deferment on that aircraft in the digital data records at the maintenance facility... Deferments Have to be authorised by the AMM (Aircraft Maintenance Manual) and the number of flights / time the deferment could be applied before the aircraft would be grounded .. Basically, a deferment is aka a 'band aid' temporary solution , to get that plane to safely reach it's next destination...

[@pensivelyrebelling]

@@michaelmartinez1345 I don’t disagree. I was pointing out the irony of the dedication of these pilots meaning everyone died. A policy discussion about when an aircraft should be allowed to fly is obviously necessary. The pilots did nothing wrong, even if policies need to be put in place to better protect everyone in planes. To me, this has a tangential relationship to the point I made. There are many cases where aircraft have gone down due to pilot error and poor performance. This is not one of those cases and that’s part of the irony.

WoW! This story sounds amazing because you have two completely separate issues that fed off each other to cause a plane crash by a principle called Coupled Harmonics.

[@ShaneShane2510]

I know nothing about planes. Never been on one. Many things seemed to have led up to this but from what I understand (very well could be wrong) is the bolts on the tail fin 3-4 have not been replaced. The military jet got very close and that F16 could have disturbed the wind path and put force on the tail wing causing tail bolts snap. Bad parts, weak parts. If those bolts where what they where suppose to be, it would have turned out different.

[@davelowets]

The amount an airline pays out in lawsuits when a disaster happens probably doesn't come close to the amount of money saved from using cheaper, unapproved mechanical part.

I have another theory. Instead of the vibration causing the tail to fall off, it was a sudden jam either one direction or the other super hard during mid flight 😮 this would be because the copilot was looking up at the F-16 and swallowed his toothpick 😮😮 Imagine the horror as he jammed the floor rudder either one way or the other. The crappy bolts couldn't handle that kind of pressure in mid flight 😮 So imagine that Captain caught off guard as his friend grabs his own throat and pushes on the floor 😮 🤔 just thinking... Maybe

[@MyTube4Utoo]

They mentioned "resonance" and "Coupled Harmonics" in this video. To see what resonance can cause, lookup some videos of "Ground Resonance" in a helicopter. It's caused when the main rotor's rotation becomes unbalanced, and it can cause the helicopter to literally shake itself apart. Often within seconds. That's in a perfectly fine helicopter, too.

[@michaelmartinez1345]

@lawrencenay8671 , Several Airlines DO have lists of critical items for safe flight...

[@petep.2092]

Why? The failed generator was not the cause of this accident. Applying random "solutions" that don't fix a problem is not intelligent and may even cause harm.

[@petep.2092]

The airplane was not unairworthy because it was dispatched with the APU running to compensate for the inoperative engine-driven generator. You made that up.

[@davelowets]

​@@petep.2092Yes. The APU was not designed to provide power for flights. It was used when it shouldn't have been used. Bad things happen when equipment is used in a manner that it was designed to be used in.

our APUs were always external to the airplane

[@davelowets]

31:55.... I'm not so sure about that. The complaint of excess vibration, and the broken mount of the APU, is pointing to a faulty out of balance APU rotor that shook enough to break one of it's mounts and eventually shake the tail structure enough to cause it to break off the plane due to fatigue cracks. I am not an airplane mechanic, but this theory makes sense to me so far. MAYBE the military jet flying close enough, and fast enough, caused a surge to the smaller plane and the weakened tail structure failed and broke off then. It probably would have been able to handle the shock if the tail wasn't already weakened due to the vibrating APU.. 🤷🏻

[@Bambihunter1971]

My question is really why is said bolt selling for $200. Likely because it is for an aircraft. Same part, same Rockwell hardness spec, diameter, thread pitch, etc. and sold to industrial sector it might sell for $45. I understand the parts made for aircraft might fly people, but the same spec industrial parts might actually protect much more lives than an aircraft so that argument is countered some. It reminds me of the same argument of why prescriptions are more expensive in some places (like America) than they are in others when they cost the same to manufacture. I get liability insurance is a big cost and is a factor in both examples.

[@premkudva]

If the CVR had nothing on it after the flight took off, how did the airline know the Norwegian F-16 had passed by. In the investigation they don't mention except for an unidentified object they saw on a military radar.
