Airbus 320 families and Boeing 737 Main Landing Gear comparison

Main Landing Gear on Airbus 319 and Boeing 737.
welcome back ladies and gentlemen and today’s video is going to be about a comparison of two different aircraft and two different manufacturers. We will be discussing the major components on the main landing gear of the airbus A319 and the Boeing 737. A brief understanding of certain components, similarities, and differences.
This turned out to be a very long video, I thought I was going to be short, but oh well, a few things I did failed to mention is some options. Options on both manufactures, such as Airbus and Boeing does offer the feature of a TPIS, which is tire pressure indicating system. Our aircraft did not come equipped with that. It cost more money 😅. Another thing I did not mention is that Airbus runs Carbon brakes. The Boeing, 737 NG has steel brakes, but all of them are slowly converting to carbon bricks, the Boeing 737 max comes standard with carbon brakes
these are just some of the few features that I did not get to you, I hope you guys all enjoy the video. Please feel free to comment, and share your knowledge amongst our Aviation community.
And a big shout out to the man who created the music you hear in the background, he’s an amazing and talented artist @samvinson.ig

Another great video. An important feature of the Airbus (SAFRAN) landing gear design is the inverted shock absorber that keeps the seal out of the dirt where it can be degraded and eventually leak. Leaking landing gear struts on an Airbus are non-existent.

[@StigAviation]

You are correct. But I have seen it lean very rarely. Good news is that it has a built in secondary seal that we can activate. Smart design.

[@steliomundt3443]

I like your videos very much!! :) But it would be nice if you can put some more nice facts in to them. Like how often the aircraft needs new brakes or tires :)

[@StigAviation]

I try to do that in most cases. But to answer your question, brake and tire wear is unpredictable in the real world environments. Too many factors to consider.

[@endtimeawakening5557]

You make this stuff understandable. Thanks for taking the time to explain it. God bless!

[@ScapoloMichael]

It’s very rare to see those, I actually made a video on this, not too long ago, it’s on Instagram, but I will repost it right here.

[@Solruc_]

The hdr of this video burned my retinas but it was worth it

[@StigAviation]

My apologies on that. I didn’t realize it was so bright

[@benjibatch]

Wish you would’ve showed us retraction and extension on the 737 as well as the A319

[@StigAviation]

I will next time we do a 737 gear swing

[@thomash2806]

One good thing about the 737 is that the WOW sensors inhibit the stall warning so you don’t get a stall warning on the ground. Airbus inhibits the stall warning under 50kt IAS as far as I know. This has proved problematic in certain accidents, like AF447 for example, where erroneous airspeed information from frozen pitot tubes led to pilots discounting the stall warning because it was deemed unreliable. We know how that ended… 😢

[@StigAviation]

Ya that was a bad one on 447. But that wasn’t the only factor that contributed to the incident. So many things went wrong and lots of pilot error.

[@thomash2806]

The pilots’ errors were largely down to the plane misleading them and to a faulty pitot that the manufacturer knew was faulty. Pilot error is very useful when the pilots are deceased and you can’t say the part and plane makers knew.

[@SSaugaCriss]

are each planes tires psi fairly equal or does it vary by mtow?

[@StigAviation]

They vary from aircraft to aircraft. But I’m general most are around 200 psi.

[@njjeff201]

Hi Stigy…. I was wondering upon landing do they do more braking from reverse thrusters or wheels? Also tire balancing… I’m sure it’s not like automobile tires with wheel weights is it? TY Sir

[@StigAviation]

It’s about 50/50. Also depends on length of runway and pilot. I seen super hot brakes because it was set to maximum braking and I seen cold brakes because the thrust reverser did all the work and braking was minimal. It’s a very dynamic situation where many factors come into play. As for balance of wheels. They come pre balanced from the overhaul shops. We don’t do that on the line.

[@GearboxEnt]

Thrust reversers, not reverse thrusters :)

[@EstorilEm]

Thrust reversers are most effective at high speeds (important to get them in quick, also why they’ll stow even though you’re still moving rather quickly.) In certain conditions, TRs do a lot of the work - ie. rain, snow, etc when braking action is poor (planes have an INSANE amount of inertia with a relatively tiny contact patch with the tires in which to transfer that energy.) I spoke with some crew (I believe it was Virgin America with one of their brand new A320s) and asked why they didn’t use any TRs at all, and they said it’s SOP to use moderate braking with their carbon brake-equipped Airbus fleet if conditions allow. It’s actually cheaper (they have excellent wear properties) than using the fuel and maintenance associated with deploying the reversers. 😳

[@ferrariguy6389]

I work both Scare Buss & Being. 33 years. The Scare Buss is a nightmare to work on.

[@StigAviation]

I think both are good. I have no problems with airbus or Boeing. Both easy to work on

[@tuskeddragon9147]

I was watching this in a dark room and that first diagram nearly blinded me

[@StigAviation]

My apologies on that, I don’t know why it came out so bright.

[@cjswa6473]

Only thing omitted is the strut switch that tells many things the airplane is on the ground..rt main for the Boeing. All Boeing pilots should know this. When able, feel for the ground with the Left main..the right one will cause ground spoiler deflection and can ruin a nice landing.😊

[@StigAviation]

You’re absolutely correct, the cable that runs up to the spoiler actuators to activate them it’s funny they only put it on one side 😅. Boeing doing Boeing things I suppose 😂

[@cjswa6473]

​​​​@@StigAviationand if I remember correctly...on landing..wheel spin up and strut compression,/sqwat switch..and some sort of timed relay. You can actually " fool the speed brake". On a really, really nice landing. The speed brake auto arm will just make a clutch sound but boards don't come out. Yes,,this landing can be done...but the pilot has to understand the whole system. You must land on the back side of the tires. 98% of today's pilots have no idea what I am talking about here 😮.

[@Zamboni-ms5iq]

Used to be a Boeing fan, but this channel is making me kind of an airbus guy

[@ccubsfan94]

Less than half the fleet at my company has brake sensors. Theres a flag that comes up in our landing data if we land heavy and or short runways and need min brake cooldown, usually 60m turn. Some of our aircraft have the temp sensors, but dont rise in temp that wildly. We use a carbon brake from France but believe were switching soon, so well see how that works.

[@StigAviation]

Most pilots I talk to seem to enjoy the carbon brakes. They say they can feel the difference

[@ccubsfan94]

@StigAviation They stop very well. The only oddity is they wear faster from small applications, so it's better to let the plane speed up then romp on it during taxi.

[@StigAviation]

It’s all about the settings of what pilots put in. You also have to taken into consideration runway length

[@andrescastaneda8833]

Stig, I was wondering if the engine PMA needs to be change often?

[@StigAviation]

Very rarely that fails.

[@andrescastaneda8833]

Thank you Stig!!!

[@andybenn]

Do an A330 that is an interesting shortening mechanism everyone would appreciate.

[@StigAviation]

Unfortunately, we don’t fly the 330 anymore, they’ve been decommissioned. But the mechanism you were talking about is actually very fascinating.

[@NicholasRiviera-Dr]

The shorting mechanism is a design wonder 👍

[@basiltaylor8910]

Geeky tech!!! more to go wrong, and another issue, the A319 main undercarriage leg has a TRUCK a single two wheel axle, not a bogie, like those on a skate board. A bogie is a strong frame mounting two or more axles and wheels in tandem one behind the other.

[@StigAviation]

I’m glad you are very knowledgeable about the subject

[@basiltaylor8910]

Yes and thanks for your kind comment, it is appreciated as an aeroplane undercarriage is like the foundations of a decent house. Get the foundations right, building the rest of the house is easy. I live barely thirty miles from the Dowty(Safran) factory, set up by its founder George Dowty in the early 1930,s. @@StigAviation

[@basiltaylor8910]

Regarding the A319 oleo leg not strut, its upside down shock absorber cylinder and seal, a unique ,practical solution. Keeping these important parts away from dirt and brake dust when operating from poor or loose surfaced runways. Looking like a Luvax friction shock absorber of a 1930 4,5 Litre Blower Bentley, the secondary damper not dampener on the torque scissors is a means of reducing 'pitter patter' when the tyres contact the runway before the aeroplane squats on the main oleos,. @@StigAviation

[@slowpoke96Z28]

Does the 737 have bladders that inflate around the outer tire when they are stowed? I think I hear d that somewhere.

[@alimohammedhaider6611]

There aren’t bladders that inflate, rather a rubber seal that forms a friction fit for improved aerodynamics

[@StigAviation]

The putter tire is always exposed to the elements on the 737. But there is a rubber seal around it. You see it in the video. They look like black rubber mud flaps.

[@piyushsinha813]

Sir can you please tell me ,B737 NG landing gear it is a an angle, but Airbus it is almost 90 degrees angle

Notice that all tne bolts on the Airbus landing gear have been fitted and the lock wiring and cotter pins installed. You can tell by those simple observations it's never been in a Boeing factory.

[@StigAviation]

But Boeing also uses lock wire and cotter pins on a variety portions of their landing gear as well

[@andrewallen9993]

@@StigAviation Boeing supposedly torque down all fasteners and use safety wire and cotter pins throughout the aircraft they design and manufacture. That's why sometimes doors fall off brand new aircraft in flight and other parts wobble a bit, ask Alaska Airlines how that works😁

[@NicholasRiviera-Dr]

How often do u have to change the brake pads and is there a rotor that has to be serviced

[@StigAviation]

It’s unpredictable. To many factors to consider.

[@NicholasRiviera-Dr]

They are not like car brakes. The brake *assembly* has the rotors and stators as one unit and are replaced as a unit. That’s what the wear indicator pin is for, to see when the brake assembly requires replacing @3:00 Airbus and @5:23 Boeing

The Lockheed Gear swings (specialy C-5 and F-104) are ... lets say "surprising". I Dont know, what they consume, before they think about the Gear but it must be erase all what you have learned of easy, simple and rugged design.

[@StigAviation]

I could imagine the complexity of the C5 itself, the way it gear retract is absolutely incredible

[@nathansharma87]

Boeing does have wheel brake cooling systems in place. If the brake overheats the wheel comes off and rolls away to expose the brakes to cooling air.

[@StigAviation]

😅😂😂

[@Kandralla]

You joke but how often does a plane really need break cooling. Basically a rejected takeoff right, how often does that happen? Around 20 years ago I was told that one pound of additional weight costs an operator $50k in fuel over the planes lifetime. Probably closer to $100k now. Is it really worth it to haul three fans around for that situation?

[@StigAviation]

@@Kandralla look, I just fixed these things, my opinion really means nothing. I have no problem with changing wheels that have brake fans or that do not have brake fans. It’s all the same to me. I still have fun.

[@EG-0611]

I am suprised AA uses SAFRAN landing gears in A320 fam rather than Collins.

Since you're at a hub can you also work on regional jets or is it strictly mainline aircraft?

[@billyrayband]

Most important difference, how short 737 gear is. Easier loading but hard to put bigger engines without dragging on ground.

[@StigAviation]

That’s why on the 737 max they had to raise the nose gear to accommodate for the larger engine

[@billyrayband]

@@StigAviation Yes, the 737s advantage over many years caught up with it and gear had to be changed.

[@savagecub]

Having been a captain on both 737 and A320 I tell friends traveling in less developed parts of the world if you have a choice between an airline operating 737s vs. A320s………..pick the one flying A320s !!!

[@StigAviation]

The 320 is definitely the smarter airplane, that’s for sure

[@EstorilEm]

My friend had to transition from the 737 to the 320 family and he said it was quite a revelation. Not only did it make his job easier (not just the primary flying aspect) but the architecture and software logic DO absolutely make it safer, you can seriously screw up and it’ll save your butt (just from stories and their training with the systems.)

[@fafner1]

What is Boeing's thinking in not providing cooling fan in the wheel? Because the wheel area is already full of axles, bearings, brakes, wheel speed measurement systems and possibly tire pressure and brake temperature measurement systems. Why add the weight and complexity of a dinky little fan to all the above? If turnaround time is important, provide the ground crew with some large fans they can use to cool the bakes. I have worked on the design of wheel based systems for both the A-320 and the 737 and the A-320 is a real pain from the design standpoint in that you have to accommodate the design to all the wheel options Airbus has offered over the years as well as the presence or absence of all the different cooling fans. We had to send an engineer overseas to Airbus for a week just to nail down the actual size and shape of the volume that was available for our equipment.

[@StigAviation]

I don’t have a dispute in regards to this, remember, I’m just the maintainer of these aircraft. The manufacturer will do whatever they want to do in regards to design. I personally don’t have a problem with Airbus design, nor with Boeing design, it’s just different mentalities and different procedures. But for me at the end of the day, it’s just nuts and bolts.

[@NicholasRiviera-Dr]

From a maintenance point of view the brake fans can be a blessing but also a curse. With brake fans fitted, when the brakes are hot, the crew turn a switch on in the cockpit and the brakes cool down - simple. When we do a wheel change, the brake fan is now another thing to have to deal with. Ensuring the switch is tagged and CB’s are pulled so it doesn’t turn on while our hands are in there and extra parts to remove and install. Without brake fans fitted, when the brakes are hot we need to find the mobile brake cooling fans. Uses time to find, hopefully they have enough fuel in them and need to position them next to the wheel - not simple. Doing a wheel change, great, no brake fan components to deal with

[@SamOreo7]

[@Spyke-lz2hl]

Boeing didn’t put brake fans on because the 737 doesn’t need brake fans. I’ve been flying it for years and never had hot brakes.

[@StigAviation]

Because the 737 is not as heavy. Also most 737 have steal brakes, and the fans help with a quicker turnaround time with the Airbus.

[@priceyA320]

I flew a 737-300 for years and only one of the 20 or so different airframes I flew had brake temp gauges. So we never knew if the brakes were hot or not. Ignorance is bliss.

[@NicholasRiviera-Dr]

Our B737’s used to have steel brakes but we retrofitted carbon brakes. The steel ones were disintegrating. There have been the odd occasion when brakes fans have been required - but not many. Usually in the middle of summer, auto brake on MAX, and a lot of taxing

Airbus seems better in terms of simplicity and funcionality..

[@StigAviation]

It’s a very user friendly aircraft

[@gordslater]

biggest difference is the Boeing always has a few bolts missing

[@ayuse01]

I wonder what would happen if a pressurised aircraft cruising at 38,000 feet had a tire blow up inside the wheel well. It sure looks like there is a whole lot of mechanical devices in there,surely vital to aircraft control... . Humm... Ladies and gentlemen, we have just right aileron control available, so we'll spiral down safely toward our destination.

[@StigAviation]

It would never happen because tires and wheels have over pressure plugs and thermal fuses to release the air pressure out before the tire reaches blow out limits.

[@samueldavila2156]

Something similar has happened to Boeing planes more than once. Damaged tires retracted with those steel wires hitting everything inside the compartment and causing catastrophic damage to hydraulics. The little thing to stop tires spinning is a cheap Boeing solution to that problem.

That’s why they are offered as an option. But most carriers buy the option

[@NicholasRiviera-Dr]

Our airline has them fitted on the A330. The brake fans are used a lot

Where the taxi and run videos

[@pummeluff3322]

what?

[@slowpoke96Z28]

I think dude is a mechanic. Most I think he does is tow. He may do check rides too though.

[@stevendamani1507]

Mechanic well if he has is taxi and run license I do

[@StigAviation]

I’ll do a taxi video one of these days. I have one for brake riding on my page if you wana see that.

[@StigAviation]

I have also taxi/ run up qualifications as well. We do maintenance taxis.

[@ImpendingJoker]

As an A&P myself Boeing didn't do it because it adds weight and cost to the aircraft, and they are really not that necessary and the amount of time they save is not really worth it.

[@StigAviation]

Yup, that pretty much sums it up. Although it is nice to be able to cool it down faster when you have a brake or wheel change 😅

[@no-damn-alias]

Well most 737 have no brake temperature sensors so that sums up Boeing's way of solving problems. The problem is so little that the 737 FCTM recommends the pilots to brake in pulses during taxi to avoid overheating the brakes and tyre sidewalls. Also they recommend to release the parking brake after the wheel chocks are in to allow the brakes to cool down. On a symposium Boeing once said an "accurate" way of telling if the brakes are hot is for the captain or first officer, after the plane is on block to put their hand on the wheel hub and if they can't do so without burning their hands the brakes are to be considered hot and adequate counter measures need to be taken, without precising what that would be. Peak engineering. Also ergonomics for ground personell is way better around an A320

[@manfredstrappen7491]

I guess Airbus actually puts engineering ahead of CEO salary incentives.

[@danielbond9755]

Can you do the fan with the wheel hub exposed in flight?

[@ozz3201]

I am 100% confident that you can name (or at least recognize) every single part in a 737NG or A320 family aircraft

[@StigAviation]

That I can to an extent. It’s impossible to remember it all, I also work on the 777 and the 787, but that’s why we have manuals I can reference all the time.

[@MrCubflyer]

I dont believe boeing makes any of their own landing gear not sure about Airbus.

[@StigAviation]

I think at this point, most of it is subcontracted to third-party vendors, Bugatti Safron and many others but all of it is built within spec of the manufacturer

[@johanea]

Airbus landing gear remains in place. Boeing not so much…

[@StigAviation]

Can you elaborate on your comment, what do you mean by that?

[@yuglesstube]

Airbus is a superior design. And I'll never take a Max. Stonecipher is evil.

[@StigAviation]

Airbus got you covered 👍

[@CheapBastard1988]

I prefer the digital maintenance manuals from Boeing. To this day, the ones from Airbus do not work on my iPad. Not that Boeing toolbox is without fault, but it has been more reliable for me. Also the Airbus manuals feel like they haven't been written with much care. Example: I selected the correct effectivity, then opened the correct manual, in there it shows multiple possible locations with an asterisk: *may vary per aircraft🤬. THEN WHY DID I EVEN BOTHER ENTERING THE CORRECT EFFECTIVITY IN THAT POS JAVA BASED SOFTWARE CALLED N@VIGATOR! SMH!

[@StigAviation]

This must be a software issue on your interface my friend. Because I never have a problem with my airbus manuals. And all our manuals are digital at this point, Airbus and Boeing. The toolbox is nice especially for the 787 but the rest is still very old. The Boeing SDS is written poorly. In that regards airbus does a better job at breaking down the systems.

[@NicholasRiviera-Dr]

The Airbus manual works fine on my iPad. However, there appears to be some misunderstanding when the Airbus manual is translated to English. Some of it just makes no sense. “Make the thrust reverser unserviceable” - what does that mean? Drive a tug into the side of it?

[@savagecub]

Brake fans ??? ………..Brake fans ??? ………Are you f*cking kidding me? 737 doesn’t even have brake temperature gauges !!! How would you ever know when to use brake fans ???????

[@StigAviation]

What are you talking about my friend ? Can you put some context behind your comment?

[@savagecub]

@@StigAviation The Airbus has brake temperature gauges in the cockpit. You can see the brake temps. Boeing you have no idea ! No brake temp display in the cockpit.

[@StigAviation]

@@savagecub yes because it’s an option that the carriers don’t buy. There are temp sensors that can be installed as well as tire pressure sensor. Just options. That’s all

[@savagecub]

@@StigAviation I have operated-300s, 500s, 700s,800s &900s for two different airlines. Never seen brake temp gauges. I don’t even know where Boeing would put them since there’s no EICAS in the 737. I have however operated A320s for an airline that did not buy brake fans. At least though we the had temp gauges so we could at least see when the brakes were getting hot.

[@StigAviation]

My friend, I completely understand what you’re coming from, but you’re comparing two different manufacturers that have two completely different mindsets and options. Either way break temperature is obviously important but not as important to Boeing on a 737. But take a look at the 787. Completely different perspective right!

[@LeemWills]

U talk to much just get to it

[@StigAviation]

Will do. Thank you for the suggestion Wills. I appreciate you taking time and watching.

[@NicholasRiviera-Dr]

@@StigAviationkeep talking bro. Next people will complain that you don’t explain enough 🤦‍♂️

[@ntal5859]

Boeing is the atypical cheapness of the USA made crap.

[@StigAviation]

Well I wouldn’t necessarily say that. But lately quality assurance has been a bit lacking.
