Tech Tuesday - Gulfstream APU Removal

[@mrterbang]

After 13 years on the type, I never saw an APU removed. You learn something every day.

[@adamdarnell7996]

You’re very welcome Shaun. Hope your fans like it.

[@spanieaj]

You might have to get your own KZbin channel for the maintenance side of Corporate Pilot Life. A spin-off (you might say). You did a really good job on this video.

[@BenDoverII]

A+ sir...

[@flyoverfredusa]

Thanks Adam, great stuff !

[@atubebuff]

Great video and commentary Adam! Approx how heavy is the APU?

[@donc9751]

Thank you Adam! Great job on the video and that APU must be almost like what a pace maker is to a heart. I couldnt help but think of how hot it must have been working in that hell hole! Been a few years since I visited Florida, but it was this time of year when I was there and the heat and humidity there was worse than anything I experienced when I lived at Ft. Hood / Killeen TX many decades ago. At 630 am it was awful, I hope you were not on there for long! Now you've got some fans of your own Adam! Thank you!

[@daveneely8692]

It is Great how the company is supporting you. Pass a thanks along to Adam and the rest of the staff a thanks!

[@ColdCanuck50]

Please give our thanks to your employer for being kind enough to make this video possible, too....cheers.

[@richardarnold3812]

I like the fact that co workers are happy to get involved,great video.

[@chuckeberth4370]

That was great of Adam to help out. The APU is one of those things you flip a couple of switches and it starts and provides power. You never think of it having to be replaced. Thank goodness for A&P's.

[@spanieaj]

Adam did a great job videoing and explaining the components that goes into the APU and the removal process. Very cool!

[@niceguy2171]

Thank you Adam so much for filming that for us! Fascinating to see a major component of the plane get pulled, and would even watch you find what's wrong with it. Although palletized like it is, means a rebuilt unit could be put into place.

[@ChaitanyaAysolaINDIA]

Sounds like a good design to have a self-containing and self-extinguishing fire box in a fire situation. Thanks for sharing the video.

[@davisc1926]

Wow, this brings back a lot of memories from my design years! This APU looks very similar to the Honeywell unit I did prototype work on from the G5. If I'm not mistaken, the engine spins at around 45,000 rpm!

[@billnicholson2470]

Very cool Shaun. Hats off to Adam and everyone involved. Thanks for this. Love the tech stuff,

[@kevincollins8014]

First off thank you Adam for taking the time to do this . As always thank you Shaun for your time as well. You both are greatly appreciated!

[@shadowman3320]

Watch out Shaun, he could have his own channel soon! Great job, Adam!

[@Big.Ron1]

Very cool. I should have guessed it had a GTC 85 in there to spin up those big Rolls Royce motors. Great video showing what the a&ps do. Thank you.

[@trinipilot2246]

Great vlog Shawn, and thanks to Adam for the great video!!! I deal with APU’s on a commercial airliner scale, but they are pretty much all the same. So it was nice to see it on the corporate side!!!

[@CGK3001]

Awesome vid! Thanks for all involved 😃👍🏻

[@Tom_YouTube_stole_my_handle]

Adam has a talent for this. Great job.

[@fredthorne9692]

THANK YOU ADAM. Very cool, and amazing how ease of servicing is building into design. A highly technical, rollerscate with wings. But, the most intricate machine that makes it all work has two eyes, two ears and a cerebellum. Take that AI.

[@richschindler8731]

Me thinks you’ve found your new tech advisor. Well done. He also made it sound much easier than it is. I’ve done it a few times and although it’s not too hard, it’s not all that easy. This is the nice part of being retired, I can sit back and watch others do the work. Still miss flying though!!!

[@Searider76]

Great video! You've got some great folks working with you there to help with your videos!

[@vetterfellow]

Thanks Adam and removal crew.

[@williegillie5712]

I really enjoyed watching greg’s video. Thanks Shaun for putting it up on the channel. Thanks Adam for taking the time to show us how it is removed to be serviced.

[@examiner0078]

Thank you Adam! I really appreciate your time and that of your team. Thank you too Shawn. Have a great rest of your week and as always be safe! God bless. Chip

[@mikedavis5397]

Thank you and the crew for the tour, it’s very interesting for me since I’ve been a wanna be pilot for years. Special shout to your corporate for allowing you to share. There might even be a few things they weren’t aware of. Thanks again. 👍🇺🇸

[@Kelly-jc3jc]

I've been working around corporate aircraft for almost 30 years and have never seen that. Nice job Adam and thank you Shaun for sharing.

[@cmans79tr7]

Saw the title and planned to hit like even before seeing the vid. Then you came on and said you weren't there...oh oh! What a great guy for Adam to step up to the plate, videoing it ! I wish I could've hit double like! Add me to the list of people who are curious as to why the APU had to be pulled, and what the next step was going to be.🤔

[@misterstuff7270]

No disrespect, that might have been the best tech Tuesday video ever

[@Col-Hogan]

Well done!! Adam would be a great addition to tech Tuesday!!

[@AquarianNomadic]

No clue, but the engineering by man is incredible!

[@alterrex6921]

You and P1D are the two best aviation channels on the platform! Love the content and Adam did a great job! He should be a regular host on tech tuesday!

[@dgw671]

That was a great video! Good job to Adam for taking the time to record while busy removing and installing an APU! Thumbs up!

[@michaelreed1380]

Thanks for taking the time to post and a big thanks to Adam for taking his time to do that for you and the company for letting you guys do that, very cool!

[@caryfields3927]

Thank you Adam and Sean for this great snapshot of the APU removal;always wondered what was going on inside that area awesome guys,

[@dschell1961]

very cool,everything is so compacted in such a tight little space

[@kenbryant2570]

Wow. Adam has missed his calling. Awesome job. Thank you so much. I learned a few things today.

[@michaelthompson4269]

Great video Shaun. I’d like to see Adam make an APU change on the Hawker look that easy.

[@CorporatePilotLife]

HA! Good luck...

[@BoB4jjjjs]

Well done Adam and the team, your a star. Thanks for sharing.

[@flyby420]

That's pretty cool how it's easily removed and paletized like that. Thank you for sharing.

[@do8472]

BTW, CPL is the first click when I get home from work and see the bell. Thanks to Adam, outstanding!

[@petejones4808]

Much Kudos to Adam! Greatly appreciated video and a great team effort to film, edit and get it out for us. Thanks so much guys.

[@Superdavey2002]

Awesome job Adam! Thanks so much. Love the Tech Tuesday series. Please keep them coming as much as you can.

[@ivoryjohnson4662]

Thanks for taking the time

[@hommie789]

Sorry shaun, love all your tech video's but this one tops them all. Excellent video and loved it and yes a big thanks for filming it for our pleasure.

[@doctorjohn-burgtekie]

Thanks to all involved in the making of this video. Now what all does the APU do?

[@doctorjohn-burgtekie]

@Evan S Thanks Evan for the reply.

[@mellentine]

Next time he changes out the TROV or relief valve, have him film that. We build and repair them in TUS, and have been told by Gulfstream that the primary cabin pressure valve (TROV) is a royal pain to install and remove. We get them with the actuator beat to hell from the installation process.

[@larrymayberry2312]

Awesome video. Love the technical stuff...

[@phillipsiviter2024]

Thank you Adam for sharing this, knew that this has to happen but not how. Fascinating stuff.

[@chucktx5957]

Excellent! Thanks Adam! Thanks Sean!!

[@johns8771]

That hell hole is downright spacious. Try crawling up in one on a Huey. Definitely not for the claustrophobic.

[@beandrive]

I know right? I remember having to change out the engine deck on the Huey and going in the hell hole in Fort Hood, TX during the summer. Good times

[@seatravel8536]

Awesome video and thank you Adam! Learn something new and cool today. Kudos to the company for allowing theses videos.

[@jodimiller7931]

well done Adam, thanks for sharing with us CPL.

[@TheFamilyman7]

Having a tech like him on your Team should keep your crew's BP down. Nicely done!

[@nitsascar1985]

Thank you for this great Video and many greetings to Adam he really did a great job.

[@graysono]

Awesome! Thank goodness a bright designer made it compartmentalized and easy-ish to remove! Otherwise you'd be spending ages in the hell hole. Im astounded how small it is considering what it does!

[@Dan-nh8nu]

Video quality of your camera is mint

[@StealthParrot]

Thanks Adam & Shaun, that was really neat. Tech tips are fascinating.

[@nzcyclone]

Thank you Shaun and Adam, well Adam mostly but to the whole team there who seem to be supporting you and your channel :). That APU didn't look that large. Somehow I strongly suspect its cost is even larger.... Question Shaun. Can an aircraft still fly with an inoperative and or removed APU?? I would guess yes but with restrictions. Take care everyone and keep safe out there, look forward to the next wonderful tech vid :)

[@ice9100]

Great video! I missed working with the GIV cheers!

[@marktaylor8263]

Great job Adam. Very interesting. W/O you guys the plane would never get airborne. 👍👍👍

[@jerrymullen9661]

Plug and play. Great job.

[@apterex]

Great work Adam thank you

[@chriholt]

Big thanks to you and Adam, that was very interesting!

[@Excitable67]

So very cool they did that! Interesting to see. Thank you!

[@ThomasR119]

That was very cool. Thanks Adam! Great video!

[@projekt6_official]

Great explanation and lots of detail! Well done, guys!

[@erick7862]

What legends!! Great vid Shaun!

[@waynemagin2554]

Thank You Adam !!! Great content !

[@BeechSportBill]

Wow! Looks like the engine of my Prius!

[@bigd-1-channel514]

Nice job Adam. keep them coming Shaun

[@JoMoJack]

Adam, you did a great job! The way you talked reminded me a lot of AVE, especially when you said "Ladies and Gentlemen, ..."

[@charlessteven8825]

Wonderful never seen before.Adam thanks for the Video and Shaun we love.Lots of greetings from Germany

[@andrewleatherman4931]

That’s an awesome video! Your team seems great! Thanks for the video.

[@jerrykorman7770]

Good job, Adam. Shaun, here’s your final check, there’s the door. Kidding!

[@howardmarshall1696]

Damn that new camera pulls great footage. Clarity. Thanks always Shaun

[@GeraldLaumeyer]

Awesome video Adam did a great job

[@Langelierdesigns]

Very cool!!! Thanks to Adam!

[@do8472]

Seriously cool! Thanks so much. "palletised" = smart engineering. Be nice to your A&Ps!

[@datruth9872]

Excellent ! That was good ! Like tech tuesday. LATER !

[@raymondmcnamara9550]

Thanks Adam

[@Lee-in-oz]

Thanks heaps Adam - and Alairion management - for letting this happen. Adam, do you find having thing like the APU palatised is easier for maintenance / accessibility?

[@Xpyburnt_ndz]

Kudos to Adam! GR8 vid guys!

[@danward8720]

Very cool. Our shout out to Adam. What is the fuel flow for it when operating?

[@kevincollins8014]

I always wondered that as well. But my question would be do they have to calculate for fuel burn while it's in use? Kind of the same question just worded differently I guess.

[@gregoryknight7986]

About 300 lbs/hr

[@G650Owner]

Well done gentlemen.

[@starman10548]

Great video. Thanks Adam.

[@AviationNut]

Wow, this is awesome, Adam should make videos he is good at it and he would have some amazing content. Thank you Shaun for posting this very interesting video.

[@tedferkin]

One quick question I do have, where does that inlet duct get its air from?

[@1biggun712]

Keep on keeping on top of the clouds 👍👍🤘😎

[@torgeirbrandsnes1916]

Great stuff! Thanks Adam! I learned a lot today. Cool!

[@SmittySmithsonite]

I'm betting I could buy 2 new fully loaded pickup trucks for what that unit costs! Thanks for the vid Adam, and thanks for posting it, Shaun! Super interesting!

[@danielmills-thysen9807]

Super cool! Thanks.

[@dennisdalessio8238]

Great video and wonderful explanation. Thanks

[@funkengruven7773]

Does the APU on the G-IV actually assist in engine start by diverting bleed air or is it for back-up/auxiliary power only and the engines start themselves? I used to start military jets many, many moons ago on the flight line with our version of a "jet engine in a box", but it occurred to me the engines on this style jet probably don't need bleed air to start???

[@superskullmaster]

FunKen GreuVeN the APU in this instance only provides bleed air for anti icing. The engines use a starter generator for starting.

[@gregoryknight7986]

The APUair IS used for eng start, NOT to be used for Wing AI

[@702Wolfi]

Someone give this man a youtube channel!

[@petermacpherson4192]

Do APU's have a TBO time like regular engines do? What's the overhaul cost of an APU? Those small fan blades are pretty cool.

[@west1304]

Hi thanks for sharing, did this APU fail in service or was it changed due to maintenance and product life span conditions?

[@SomEto]

Great Vid Again,Thanks from the UK

[@kencolson]

Thanks for sharing.

[@scottlambert2609]

That’s really cool to see!!

[@beandrive]

Thanks for the upload. Just for the record, why pull the GPU?

[@flyoverfredusa]

Thanks Adam !!
