Broken Equipment on a Private Jet! - Tech Tuesday

This is a short description of a Minimum Equipment List, or MEL, and how it works. The MEL is how we are able to operate when we have broken equipment. I hope you enjoy!

Possibly one of best tech Tuesday vlogs you have posted Shaun. I found it be very interesting. Thanks for the time you take to make these.

[@CorporatePilotLife]

Thank you!

[@johncollier608]

I love Tech Tuesday but this one was really, really interesting. Thanks, Shaun.

[@W1RMD]

I appreciate all of your videos. Thank you for explaining the technical things too. I would like someday in the future to see more tech videos, especially radio and navigation equipment. Thanks and keep up the great work!

[@dougf94912]

Fascinating, thanks for walking us through this!

[@danielmeans4498]

Interesting video. Glad you all were safe

[@nancyinlow4904]

Well that was interesting...and comforting... to know there are many backup systems ...love your tech Tues...

[@johnzimmy9590]

Shaun, Very good explanation of use of the MEL. It has been a little while since I worked on a G4 but forgive me to say that selecting "ND OFF" is using the selector switch at top of overhead panel. The knob you showed was just the brightness knob. I'm retired now but anyway good job. Lots of times the filters get clogged with carpet fibers and the unit (DU) fails. Each DU has a conical shaped filter that needs cleaning on a scheduled basis.

[@MBa-gd6nm]

Great documentary as always Shaun!

[@billnicholson2470]

A lot more involved than I thought. Thanks Shaun

[@MattyCrayon]

Have to agree with others here. I love all the tech Tuesday vids, but this was was really fascinating. Glad you were able to get the mission accomplished. If you know any kids. I was finally able to post my C172 flying video for kids. Had to wait a bit, while I got permission to actually show GoPro's attached to the windshield during takeoff and Landing, but after CASA here in Aus said it was ok, I put it up last week. All the best and keep the great videos coming.

[@andymugridge5034]

Very informative 👍

[@G4Disco]

As a maintainer that is trying to become a commercial pilot, repairing things myself will be difficult to resist.

[@richardschindler8822]

As being the pilot / A n P mech this is where I would have earned my pay. I would have taken my pilot hat off, put on my mechanics hat and went trouble shooting, fixed or MEL’d it. If we were at our home base we would have had an extra screen in stock and I would have thrown it in. If we had a piece of equipment that was common to several of our aircraft, we always had those items in stock. This would have been one of them. Happy flying !

[@adamdarnell7996]

These screens are $98,000 each. No one keeps spares in house.

[@rmaracallo]

Great to see you troubleshooting real world problems

[@all_golde]

We miss the g4 flights, please bring them back soon

[@torgeirbrandsnes1916]

Great tech vlog as always! I have my 120h TT and 20h PIC. When I worked for SAS (SK) as Red Cap, one day I had a flight with FI to KEF, a 757 the copilot tells us that they are AOG due to a snag. They were just going to inform us, the ground crew that had to cancel the flight and they were going to call OCC/OPS and let them now. So I asked the FO «Did you check your MEL?» He looks like a question mark, thinks for a few sec and says «No, I will do it now» He runs into the cockpit and less than a munute later he calls and says that we can start to board in 10 mins! Another time I was a pax on a FF (Tower air) from OSL-MIA. The flight was 3h late from the gate due to a strobe light did not work. They had to get a new one flown in from SVG. Once onboard we was told that 10/12 lavs was U/S. That was FF for you! There 747 was all line no before 50! Made in 1969/70! Pan Am was the most worn. BA/LH had kept there 747s as good as new almost.

[@G8R8R]

Psst...did anyone check to make sure that the display brightness was not turned all the way down? (old mechanic joke). Mechanic is the hero when the flight is not missed.

[@chrisk2097]

Very interesting and well done... By the way your last tech video you were showing us how to gut out a plane. Were you able to get any footage of them putting it back together? That was pretty cool!

[@tonytango6676]

This is the kind of video to show to someone who has a fear of flying. Or even some concerns.

[@dmacdonell]

Shaun, excellent video, thanks as always. Aren't you able to switch displays electronically? In other words put the necessary navigation information on any of the six displays? Or the most critical information for the given situation. I always thought they were electronically switchable.

[@Breenild]

The redundancy is for, that you will not get big problems, when one device quits in fight. But when you takeoff with one device broken, then you don't have a redundancy anymore. When then one device fails, then you are in trouble.

[@edpippin]

You better not mess around long I hear that Operations Manager you guys have can be a hard ass...LOL

[@gtr1952]

Thanks Shaun, very interesting! 8) --gary

[@jimtorley70]

Who (or what group) generates the MEL for your specific airplanes? I can see that the factory would have a basic MEL but does your company augment that MEL and is it required to be "approved" by the FAA? Great video as always! Thanks!!

[@jimdougherty2758]

That was really interesting, didn't know that the DU's were that easily interchanable. How long can Honeywell keep those CRTs (cathode ray tubes) flying?

[@CorporatePilotLife]

They are not making new ones anymore, they just refurbish the ones already in service. There are still several hundred planes out there flying that use them (G-IV and G-V both use them). While the demand is there, they will continue to support it.

[@johnfitzpatrick2469]

G, day Living the Corporate Pilot Life. The Minimum Operations Proceedures Manual for that plane; is that FAA requirement or Manufacturer of the jet? More so, will that information be used in the annual inspection to determine replacement components of the jet?🌏🇭🇲

[@chrispistel5221]

Can you put any data on any display, or is each display dedicated to one function? In other words, if that unit failed in flight, could you bring up engine instrumentation on another display to continue the flight? Same thing for other display info. Can you give up nav data on one seat to get primary flight displays for both pilots (assuming display 1 or 6 failed in flight)

[@royalfred06]

Have you or are you a member of the "Mile High Club"?

[@1ytcommenter]

if they replace the unit will the replacement be again a crt display or will the new one be an lcd?

[@philanderson1200]

Reminds me of Presidential 69 display going out during the flight to Vegas.

[@CorporatePilotLife]

I was wondering if anyone would remember that one!!

[@Subgunman]

CRT displays? If so it would be nice to go to newer avionics ( ouch except for the painful cost ) one could also lose a few hundred pounds of glass and lead. It is nice that they are "plug and play". More than likely a bad power supply, thank god they don't use cheap Chinesium components in these items so MTBF can run for quite a few years between major service. Wonder what a refurb unit will cost?

[@CorporatePilotLife]

I'll have to ask about the refurb cost of one of these, but my guess is several tens of thousands of dollars.

[@ILM787]

MEL list is an opposite concept just like “near-miss”.

[@RogParish]

Was that display a CRT or a flat panel?

[@peterahjorter]

I like these informative videos, I follow you and Björn_pilot for aviation videos

[@davidfarrish9000]

Tell me what was that screen cost? I know on the Cirus it’s a fair bill

[@falcondrvr200]

IIRC, they were around 40k back in 2015 but I could be confusing that with another component. Most operations have a contract with Honeywell that sort of “insurers” the components, so when they fail, you don’t come out of pocket for the whole cost. I don’t remember the full details but I think the program was called Bright Parts and Duncan serviced the program for me. I’m just an airline cargo pilot now so I don’t have to give a crap anymore and have forgotten many details!

[@320Scott]

A bit more involved than TOMATO FLAMES!

[@chrisc161]

Were you at your home base? It seems that because maintenance has the parts.

[@CorporatePilotLife]

Nope. We were out, but had another maintenance company local and was able to get the parts quickly. We were in Wyoming.

[@jeffreygosselin1143]

D.M.I. Deferred Maintenance Item(s). 😬

[@Kenny-en7wb]

Can the displayed info be moved to another screen? Avionics seem dated!

[@CorporatePilotLife]

In this configuration, no. The #2 DU shows the same info already and that is why this one is the only one that is allowed to be inoperative.

[@bartofilms]

Is there a check of the wiring/bus that feeds the failed DU, before the good unit is swapoed in? Cheers.

[@davidgreed1885]

Circuit breaker would obviously be checked, then swapping the units would determine if the wiring/bus was at fault - that is, the the known good unit would not light up once the swap has been completed - and based on Shaun's explanation would result in a no fly scenario if the wiring/bus fault could not be fixed there and then.

[@CorporatePilotLife]

That's exactly correct.

[@dannywilliamson3340]

Does that collar lock the circuit breaker open, or is it just a visual indicator?

[@darrellgordon7456]

it locks the breaker open, so it removes power from the system.

[@CorporatePilotLife]

yep...serves as both

[@aarocka11]

Where do you find a replacement CRTs?

[@CorporatePilotLife]

There are a few companies rebuilding them. They pretty much all require that you send the old one in when they send you a refurbished one. I'm not sure of the company names though.

[@thomassteele-sheets7471]

Whats the rule on if you are the pilot but also have your A&P? I'm really curious about this in the 135 world.

[@CorporatePilotLife]

Some operators do not allow that because it can be an accounting nightmare, but there is no regulation preventing it at all.

[@thomassteele-sheets7471]

@@CorporatePilotLife that would be the life for me. Wrenching and flying.

[@johnfarr2738]

Did you record this flight?

[@CorporatePilotLife]

I tried, but the GoPro shut off half way through the flight. I'm getting really tired of those cameras losing footage!

[@mentonish]

For how many years can you get replacement parts!!!

[@CorporatePilotLife]

They are not making these anymore, but they continue to refurbish the old ones. Why knows for how long, but there are still about 400 G-IV's out there and a almost 200 G-V's that use the same screens. The demand is still there to keep them going for now.

[@iisubzeroii5538]

Hi Shaun, what is the procedure if the ash tray is missing ?!! Thanks for the upload - very interesting and a side that us mere mortals don't see (or appreciate)

[@CorporatePilotLife]

I would have to pull the manual, but I believe that is in the NEF (Non-Essential Furnishings) which is similar to the MEL.

[@iisubzeroii5538]

@@CorporatePilotLife thanks for the reply Shaun!! I suppose this just relates to commercial ??? In a directive updated as recently as 2000, an ashtray is part of the"minimum equipment," meaning that if something happens to any one ashtray, an airline must replace it within three to ten days, depending on the circumstances

[@rikspector]

Shaun, Personally I've found a stick of chewing gum usually solves most of these problems:) Cheers, Rik Spector

[@davidharris2519]

if airline pax knew about MELs they would be more afraid to fly

[@tenpiloto]

You mean the ignorant pax who don't realize the benefits of MEL. Unfortunately most Americans are woefully ignorant about most subjects.

[@colinpotter7764]

Does that mean in this case that the pilot flying must be in the left hand seat?

[@bruce2357]

That would not make sense since one pilot could end up disabled. Seems more likely that the unit that can be inop. is on the right side since the captain is ultimately in charge. The right seat has what he needs to fly.

[@oldschoolnomad813]

Not 100% sure but perhaps Shaun can chime in on this but IIRC the MEL is tuned to each carriers operation policy. If you notice when he was flying PRD69 he was always in the right seat. Now with Alerion the PF is always in the left seat and PNF in the right. Same with the checklists, flying PRD69 they never called feet on the rudder peddles/off the floor or "Blue up / Brown down" on the artificial horizon .

[@CorporatePilotLife]

The MEL can be tailored to the operation, but they are generally based on the MMEL, or Master Minimum Equipment List. Nothing is written that the left seat pilot must fly, but in this case, it certainly would make sense.

[@colinpotter7764]

Wouldn't it make more sense if the Minimum Equipment List was called Maximum Defective Equipment List considering how it seems to work? 😂
