737 Max UPDATE! Wiring Issues and the FAA

[@Knirin]

Glad to hear that your health is doing to better.

[@darylnd]

Ditto! I've spent the past couple of weeks getting tests done so FAA (I hope) will issue me a Class 3 and I can resume training for my PPL. I'm getting a pile of training from Juan's videos!

[@GalenCurrah]

Many of us have prayed for this. Maybe ...

Yes!!! Thanks Knirin for reminding me. Juan... this is great news! Basically, confirms a "cure"? Now just something to watch? OK... will keep praying anyway.👍🏼

Juan, glad that you film many of your videos from the hanger in front of your Luscombe. Love antique airplanes and that one is a beauty! Never get tired of looking at it. The color scheme is fantastic. In fact, I've never seen a better one! Looking forward to what you have to say about the debris found in the fuel tanks of the undelivered 737 MAXs.

I would like to thank the folks that are financially able to support the blancolirio patreon account. As I'm no longer able to work and the run away costs of MS therapy RX makes it prohibitive for me to support this effort.

[@BennyGeserit]

And he is doing a heck of a job with this channel. I have flown on the Max already and will be listening to his take on certification when deciding to book future MAX travel. They fly transatlantic in Canada so it puts a serious damper on those plans if trying to avoid those routes.

[@fonkenful]

BennyGeserit Sorry, I perhaps wasn’t clear enough - I was musing about the Mighty Luscombe. I’ve been in a small Cessna tour around Bermuda - much more magical from 5000ft at around 100knots- and several chopper flights over Maui and the Grand Canyon. I’m sure Juan could find something in his neighbourhood worth the trip. As for jetliners, of all the Boeings I’ve flown, the 777 was my favorite, but I much preferred the A330 that Air Canada called in to make up for the ongoing cluster fork nightmare that the continued Max grounding is giving all the airlines.

[@moenaguib2947]

Agreed, Brown for the win.

[@KenMrKLC]

I know nothing about aviation but always interested..... You do a great job bridging the gap between experience and novice. I enjoy your vids

[@fxsrider]

I have closed gap covers on the 747 in production. It required me to check all clearances, safety wires, back shells, air gaps, you name it. The clearance requirements for something like fail safe wiring, or hydraulic tube proximity to wiring is clearly stated in the engineering drawings. Every now and then, there would be some inspector that would pull a section of wire in between the clamps, it does have some flex in it. Then the inspector loses his mind and is unable to understand that we inspect the clearances in a static condition. Installed, clamped, routed properly. There was no flag note to simulate 150 G's by pushing and pulling wire bundles into or toward other systems or structure. I knew when this would come up, why it was being done to start with. It sucked to go get a harness, walk up on top of the wing. Crouch down and spend the next few hours inspecting, then assisting the customer inspection etc. The QA would make it very obvious why they should never task him with a gap cover shake again. I literally wanted to beat some ass at times. What a bunch of whining bitches. There was an incident on the very first 747-400's coming down the line. I was hired away from General Dynamics in Fort Worth and put to work on the front spar of the left wing. I was avionics but that's where they put me. I had my drawings and was surrounded by new hires that had no experience in aviation apart from the training Boeing put them through. I was coming off the F-16 line, and prior to that the F-18 when it was brand new and was being introduced to the Navy fleet. Did my 4 years VFA-125 Lemoore, California. Yeah... I'm getting old :) Anyway there is a new hire that hired in prior to me, but came from the local area and had zero practical knowledge. He just knew he was the self appointed shit, until I came along. I was given the fire bottle and power feeder runs. The wiring they had already clamped up was wrong, not by just a little either. They had run both fire bottle circuits together in the same clamps, tied up nice and pretty. I said hey... we have to re-route these... There is a requirement to separate the... JUST DO WHAT I TOLD YOU!!! Build it like the one up front! The Oklahoma blueprint method was his claim to fame. Say what? I Tried to explain what was wrong in a civil tone. Next thing I know, the manager comes out, he immediately wants me moved. I was sent down line to the door on the traveler crew. I'm out of his immediate area but I am only beginning to fuck his shit up. How could he not anticipate that the first thing i would do is check the wiring to the fire bottles 6 aircraft away? LOL It was all documented and put right. There was also an investigation to determine how so many were done incorrectly. They were also stretching the wire bundles to get them to reach the end of the wing. The -400 bundles were a major problem. The form boards they built them to were not an exact science in 1988. They were pretty close but not close enough. There wasn't going to be any adding a little wire to make it longer either. Oh No my friend. Get the wire spoons out. Where does it start at? It starts from the disconnect in the 44 section. Roughly 100 feet that way >>>>>>. Through pressure bulkheads, seal fittings. What a mess. Boeing swiftly fired that manager. The first of many that I would have the misfortune of working for.

[@jonesjones7057]

Your mention of not wanting to troubleshoot the trim or pull circuit breakers and mess with it made me laugh out loud because it's SO true but so many go down the road and do weird stuff "they heard works" and create chaos. I agree 100% with leaving it alone unless it's so bad there is absolutely no other choice.

[@samstroup2685]

My old bird flight instructor told me basically the same thing, 'If you have a problem and can fly the airplane, don't change ANYTHING!' I actually used that advice once. Worked for me. sam ps; love your videos and glad you're getting back in the saddle

[@jonesjones7057]

@@samstroup2685 Yes. A funny but wise piece of advice my old school instructor taught me was, if you do anything and the engine quits or the plane does something you don't like, undo what you last did.

Brilliant news on the PSA front Juan.

[@noelwade]

Glad to hear the good news about your health! Hopefully both your skies and your medical record are nice and clear from here on out! ;-)

[@fevengr9245]

Juan: While it is true that Advisory Circulars are not mandatory, the certification plan proposed by an applicant ultimately has to be accepted by the FAA. While it is theoretically possible for an applicant to propose an alternate means of compliance, in my 26 years of working in certification, it was usually much easier to just follow the guidance provided. Great technical detail in your videos!

[@andrewsuryali8540]

It's easier in the administrative sense of breaking past bureaucratic obstinacy and the general unwillingness of administrators to take personal responsibility by making decisions. In this case, though, they may literally need to rebuild a very small part of every single plane at their own cost. That may end up proving not only costly but also very difficult to actually perform on the fleet.

[@roderickhorton7845]

Sometimes guidance with new technology should mandate a consult with component manufacturers and FAA. Then FAA would have better understanding of technology when it is too new to be fully understood and they could certify new planes or technology in planes and just move forward. Then they can make standards based on what the theories are for maintenance and repairs but they would be in contact with the people who made components. Then the inspection for installation into planes would be checked again for certification. Certification at manufacturer and certification in intended installation/use. With inspectors who have insight and are independent of any aircraft manufacturer.

[@markmatthews2984]

All these AC requirements are embedded in CS 25, sub part H EWIS requirements. The current are the latest and greatest and clear as day, confusion and room for interpretation comes from continuing to use an ancient type certificate!

[@afcgeo882]

Roderick Horton That wasn’t the issue here. The wiring isn’t a new technology. It just fell under new rules, after the aircraft was made.

[@roderickhorton7845]

Sometimes you have to ask questions even in the face of guidance. Sometimes you just have to say I need additional guidance or something.Many times even from the same organization, you will need multiple opinions or multiple approaches/concerns to be considered.

[@hgbugalou]

@@jwenting I do not understand your point. Even at its worst, the stabilizer situation was easily fixable with a single flip of the stab cut out. This is why no western first world airlines ever had a problem - their airlines were more trained up on the situation versus less developed countries. After the modifications the situation will be much better with additional probing points and no doubt a more robust system in software. There is no devastating bug out right with the Max in it's design.

[@stephendee7839]

@14:30, Boeing would not need to break up existing wiring looms. They can, instead, leave the loom alone and add new power wires in a separate group from the control wires. That would leave the power wires in the existing loom as unused and abandoned, but compliant with the proximity rules.

[@cr10001]

That would probably be easier, cheaper and safer (less risk of damaging exisiting wires) - if they can find a suitable route for the new power wires.

[@stephendee7839]

Boeing can use the exact same route and a "barrier" to separate them (although there's a preference for "space" rather than a "barrier.") There's no specific spec on the barrier. A loom sheath should qualify. A ribbed sheath would also add distance between the control and power wires. www.faa.gov/documentLibrary/media/Advisory_Circular/AC_25_1701-1.pdf

[@Inkling777]

For that 737MAX wiring issue, there's an adage that needs consideration: "If it ain't broke, don't fix it." Efforts to prevent what's known to be an unlikely problem might create another and more likely problem.

[@ethanpoole3443]

You got that confused, it goes “if it ain’t broke yet you haven’t tried hard enough!”. But in all seriousness, when proposing changes to a well proven and reliable design you do indeed want to carefully weigh the pros and cons as it is absolutely possible to introduce new unknown risks into the design that may exceed the known risks of the existing design. A more practical middle ground might be a modest incremental improvement on the existing design such as adding an extra layer of insulation between the power rails and control wires so as to further reduce the risk of the two ever coming into contact from chaffing. That, I suspect, would be far simpler and safer to implement than wholesale relocation of wiring harnesses simply to increase spacing between the two.

[@steveorshon]

Agreed! 16 instances of non-fatal wiring issues in 205 MILLION flight hours does not constitute an imminent threat. I hope the FAA doesn't succumb to a media-driven knee-jerk reaction.

[@willwarden1631]

Ethan Poole i’m 100% also system wiring and individual system hyd lines are separated so that you have a better chance of living through catastrophic damage like an engine Uncontained failure cutting a wire loom.

[@tchevrier]

that has no place when you're talking about public safety. The flip side of that adage is that they've been living on borrowed time. Engineering doesn't work on the premise that if it hasn't broken yet then it must be ok. One tool that Engineers use, is called an FMEA, to examine systems to determine the risks due to failures. They look at what can fail, how it can fail, the probability of it failing, the effect of it failing, etc. It would be reckless of them to not take a close examination of this issue as well as any others related to the stabilizers (and any other systems that are unique to the max8). Even if a failure is unlikely to occur, if the consequences are catastrophic, then it would be prudent to review the design.

And that, he says, is where all the problems are coming from. Take it for what you will, but it's an interesting comment.

Sadly a rarity these days .

I flew the B737-200 for a total of 8000 hrs and it's right behind the B767-300ER as my favourite aircraft and I flew airliners made by Lockheed , Douglas and Airbus so I had a chance to compare other manufacturers products . It's sad to see the events of the last year unfold and can only hope Boeing can get back on track and resume their rightful place as the planets premier aircraft manufacturer . I think we share a deep love of flying and when I retired in 2007 left seat on the 767 I got a job as a tanker pilot with a major Canadian operator of airtankers !

I carefully submit a comment regarding wiring. Pilots, please comment. I only follow the data and try to keep an open mind. My past experience included working through damage to electronic equipment that we transported in the holds of different aircraft. They are not all the same. We used g-meters inside the equipment and found extensive variance, depending on location. The worst was multiple harmonic vibrations generated during full-power takeoff. Considering the aircraft (and not our equipment) we then wondered why, other than weight, the aircraft manufacturers continued to use Kapton insulated wiring. (Pilots, please correct me if this is wrong! I'm looking back into the '80's.) While Kapton has benefits, it is not forgiving of high-intensity multiple harmonic vibrations, at least long-term. It cracks, and becomes vulnerable to moisture - even oxygen. Unless I'm wrong, the U.S. Navy pulled all Kapton insulated wire from their aircraft long ago. Maybe the document Juan mentioned is DOT/FAA/AR-08/2. If so, it can be downloaded. www.tc.faa.gov/its/worldpac/techrpt/ar082.pdf The confusing double-speak outcome of the study (as mentioned by Juan) serves the purpose of providing everyone some plausible deniability. The endless months of work and money spent probably did little else. Fix it if you want. This same methodology is often used in other industries. Blancolirio World HQ is one of the best information sources in ALL media. Period.

Juan, you are absolutely correct about moving aircraft wiring around. There is only so much space in an aircraft that's available to route the wiring. Speaking of wiring, when the Air Force C-5s were first built in the early '70s all the wiring clamps had foam rubber pads on them, rather than rubber or neoprene. In just a few years the foam deteriorated and in the late '70s it was necessary to replace all of the clamps on the entire aircraft. Can you even imagine what that was like?

That stabilizer trim wiring issue sounds very serious. FAA should have required new certification for the Max. Now they have a real can of worms that might not manifest for years. Not good. Sure sounds like there is a potential for more accidents down the road no matter which way the FAA goes with this.

Congratulations!!!! I’m so happy to hear of your current health status and paperwork filing. 👏🏻👍🏻⭐️⭐️

[@gomphrena-beautifulflower-8043]

So glad you’re (almost) ready to get into your 777! Juan, does your company require a type of a “refresher” course after you’ve been on leave for a certain amount of time? Say, a fling in the old simulator?

[@blancolirio]

yes.

[@jonesygw]

Glad to hear you’ve got a clean bill of health Juan. Thanks for the update.

[@turbofanlover]

Great vid, and congrats on the PSA results. :)

[@jamesmonahan1819]

I'm glad to hear you are ok, and able to go back to work. I was worried for you and your family.

[@icelandviking1961]

As an electrician I would hate to rewire a 737. I would do it but it’s going to cost you.

[@richardhaas39]

It will cost a lot since you cannot use the old cable as a pull for the new. The new cable has to use a different path than the old. That is the whole point.

[@afcgeo882]

Richard Haas Before any rewiring happens, engineers have to decide where the wiring. can even go. Not a lot of space for extra wires in a 737 and a lot of other metal structures and systems that exist there.

[@richardhaas39]

@@afcgeo882 I have seen a lot of creative cabling solutions in my time, unfortunately, all south of Chambers Street, NYC; like turning an elevator shaft into cable riser. Perhaps they could raise the floor of the cabin and run new cable there, or conduit under the seats, or ladder rack above the windows and below the overhead baggage compartment. Go wireless, use the pitot tube as a transmitting antenna and a static wick as a receiving antenna. Or, leave it as is; Verizon/Nynex/NewYorkTel/AT&T supported telegraph (the stock ticker) for over 100 years--the wires actually had cloth insulation with dope until this century.

[@afcgeo882]

Richard Haas Ironically, cables running below street level in lower Manhattan created major issues during/after hurricane Sandy. The engineers know how to solve the problem. The issue is that it’s VERY costly and the potential negative impact of the fix is unknown. On the flip side, we do know those wires aren’t a safety issue. So... can you blame them for not jumping into it? At least if the FAA made it actually mandatory, they could blame it on them if it leads to issues. As is, it’s “voluntary”, so it’s all in Boeing.

[@afcgeo882]

gene murray Nothing happened, at all.

[@GregHunt55]

Great video as usual. Your hard work, truth and accuracy is increasingly being appreciate. Bit frustrating expecting to wait a further 6 months. 🇬🇧

[@geraldo209]

Wires too close to each other. Another chapter of the saga! There has never been an aircraft subjet to such scrutinity as the Max.

Geraldo_MAX "There has never been an aircraft subjet to such scrutinity as the Max." Even the DC-10?

Concorde was, when it was first built, but that's another story...

Great to hear that you got your wings back again. Shiny side up!

[@PsychoticusRex]

Just ask Louis Rossmann regarding issues with apple products and their bloody power channels right beside command lines. Great way to brick a computer, i don't like thinking about "bricking" an aircraft. 8O

[@whizzytheelephantadventure1063]

Clinton the Cat will fix everything.

[@gordonrichardson2972]

PsychoticusRex The B737 has (slightly) better wiring safety than Apple backlight connectors.

[@redheads604]

If you want proper wiring, you can't afford it. It's just the loss factor.

[@Blackbarron247]

just check ppbusg3hot

[@UncleKennysPlace]

@Jason Bowman Yes, if you have the proper licensing.

[@PistolPackingPilot]

Juan, congratulations on all the subs! From one CA to another, your channel is refreshing. Keep up the good work.

[@Big.Ron1]

Oh Lord. What a mess. One of the things I learned as a young A&P is, you never mess with, and especially do not open, or move wires in a bundle unnessisarily. The only real and safe solution is to replace the affected bundles with new, tested bundles. Then the testing required, both ground and flight would be just one more hurdle. An irritating and not necessarily needed hurdle but there just the same. It seems to me it could be addressed at the next C & D check or whatever the next very heavy Max maintenance check is. These are new bundles so I dont see a need to rush in and create problems potentially for the life of the bundle/aircraft. It goes back to the axiom of if it ain't broke dont fix it. It seems to me the danger of a hacked up bundle out weights a new bundle of old design in a new airplane. Just an old A&P, IA, and Private SEL weighing in. Your experience may be different but I would be more afraid of the fix than the original install for anything short of a full replacement of all the involved harnesses and bundles with factory new and tested items. Good news and congrats on the PSA, I just went thru similar. Now to fix my neck and back and I can chase down my medical as well. Be safe. Thank you.

[@afcgeo882]

Ron Hunter The FAA knows this, but had to create an AD to address wiring systems that have been affected by a critical failure in the past. This wiring wasn’t affected until the LionAir crash, so no issue then, but now it falls into that category. They know it may be opening up a can of worms, so it’s optional, if can be done safely, but they also don’t want to be held accountable for repeat accidents.

[@timgear9892]

Real good report. Had not heard of the electrical issues, but, yes, very important to consider. Especially the potential of stray emf partially energizing supposedly dead wires, enough energy to hold in a relay somewhere.

[@ericgoldstein4734]

Congratulations, on the good health news!

[@davidolson7575]

Great to hear that you’re back on the road and soon will be flying again. Hope to sit in the back one day with you flying.

Thanks again Juan.. Another great Update !

[@coreyballard8359]

Glad to hear you’re back healthy again. That’s great news. Fighting with OKC is the bane of every pilot’s existence. All the best

Hello Juan, really good news on your health. Looking forward to seeing a nice report from you on one of your lay-overs (once you are back on duty). Kind regards from Austria !
