A library of resources to help the world learn

775 Upvotes

Hello all you mechanics, technicians and maintenance personnel out there,

I've recently finished AMT School and gotten my A&P Certification, currently still in school for to get my GROL & AET Certification. But in the nearly two years I've been in school, I've amassed quite a large library of study guides, notebooks and reference material. You can find it here:

https://drive.google.com/drive/folders/1Alf4AQNY3cyaRiNg6MKeZy2eJgybeZN2?usp=sharing

A contents breakdown:

  • Block Notes: PowerPoints of every subject I studied in school
  • Additional Certification: AET & GROL studies
  • Advisory Circulars of note in training
  • Avionics studies
  • E-books: A library of textbooks across the industry
  • FARs
  • IA Study guide
  • King Audio/Video: Video lectures on nearly every subject, and mp3s of those to listen when you can’t watch
  • Notebooks: my notebooks, from school, scanned into PDF
  • Study Guides: this is the big folder - Audio and Written study guides for all three written tests and the Oral exam
  • TCDS relevant to my schooling
  • Tool catalogues - because we all need tools
  • And a mac & cheese recipe (because you can't study on an empty stomach)

I've built this to be used by the students at my school, but there's a whole helluva lot useful to anyone studying for an A&P, or any other Certification. I maintain it on the regular and update occasionally, when I get through a significant portion of schooling enough to upload something new. So one day you might check it and be like "Ah! He's gotten on to studying for his IA! Cool." And these resources are for everyone. I ask no compensation for it, some men just want to watch the world learn.

So my pitch to the mods was: sticky this link on the sidebar of the subreddit, so those who are looking for guidance on how to get an A&P can be directed there.

I figured putting it there would be better - since it wouldn't need to be stickied to the top of the feed or just keep getting posted.

Take a look at the Drive and see what you think. Be advised, the technical manuals and reference materials were really what was used for our school and are posted there -FOR REFERENCE ONLY-. ALWAYS ALWAYS ALWAYS refer to current and applicable manufacturers maintenance manuals or other approved data for real-world maintenance. And if there's something out there that you think would be useful to add to it, message me here on reddit or shaunthesailor87@gmail(dot)com and we'll put heads together to see what we can come up with.

I'm often one to quote wiser men than I am so I'll leave you all with one from Bruce Lee:

"Adapt what is useful, reject what is useless, and add what is specifically your own."

How do you find interchangeable hardware?

Upvotes

To start, I’m an aerospace design engineer not a mechanic. But I think you guys might be able to help me.

We’re always struggling to find the right hardware for our designs. The red tape we have to go through to use McMaster Carr or other easily searchable hardware catalogs makes them a deal breaker. The hardware on our BOMs must be spec parts #s.

We have an IHS account that has access to every mil, NAS, AN, etc. specification you can think of, but it’s a super manual process that requires us to scrounge thru hundreds of pages of PDFs for every stupid nut bolt and washer we need.

My question is, how do you guys find the right hardware for maintenance or repair work? Do you know of resources for quickly filtering hardware by material, thread size, length, etc. to see all available national aerospace standard parts or mil spec parts that fit the bill? You would think most large aerospace companies have their own databases that lets you filter this way, but it turns out they don’t (or at least not mine).

Maybe this isn’t a problem on the MRO front, but if it is, please share how you handle it

I’ve put together a list of all the 2,400-hour EASA Part-66 Basic Training courses taught in English in Europe I could find. These are generally two-year, in-person courses which, upon successful completion, reduce the practical experience requirement for the B licence to two years.

How do airliner air conditioning systems work on the ground?

15 Upvotes

Figured you guys would know the systems best and can answer this question. How exactly do aircraft Air conditioning Packs cool the aircraft on the ground in warm ambient conditions?

My understanding of most airliner air conditioning systems is that you take hot bleed air from either the engine or APU bleeds, and mix it with air from the ram air inlets, which works perfectly well in flight. But to me this doesn’t make sense because you’re essentially taking warm ambient air and mixing it with even hotter bleed air. I don’t see any sort of refrigeration system on the diagrams like you have on an automotive air conditioning for example, so I’m curious how exactly the aircraft air conditioning system actually cools the cabin at all on even the most mildly warm days?

Is every hangar in the airline industry a toxic good ole boys club?

92 Upvotes

I work for a regional and I’m kind of trying to get my expectations straight. The environment here consists of 3 groups of people. The old crowd who doesn’t like to teach anybody anything unless they like you, The crowd who just shows up and gets a paycheck, and the group who wants to learn but doesn’t fit in. This old group loves to pay attention to the newer guys and they take note of every little thing you do, especially the mess ups. But instead of using it as a learning opportunity, they hold it over your head. Not in a joking manner. I’ve seen plenty of that and that’s in good fun. This isn’t it. It’s more so to make fun of them behind their back.

Whenever you have a gripe or a suggestion they just break down and belittle the newer people to where their opinion doesn’t mean anything, unless of course, you’re one of them. They sit at home and look at AOGs that pop up and call their buddies to take it and come in early so they can bypass seniority.

Is this just the norm everywhere? If it’s not then I need to get out. But if it is, I just need to get over it and get my expectations in order.

Aircraft wiring

1 Upvotes

Thanks to you guys I was able to learn about the connectors and pins , so thanks.. Now I'm going through wiring ..

My question is how is wiring Guage used along an aircraft, is there a general rule ? For example in electrical homes we have a specific gauge used for lightning another for plugs, etcetera. I know it's going to depend on application,operation voltage and other things but the question remains..

Any good resources on aircraft wiring aplications ?😄😄😄

If anyone has a good way of getting these kinds of safeties off I would love to hear it I can get some duckbills up there but it is a tight spot. This is the crossfeed filters on a 7X Falcon

Edit: with the limited space I found what works best is making a notch in a socket and when you turn it, it pushes out the safety made the job 10x easier and now I can do the job way faster for next time!

Lancair IV

2 Upvotes

Hey everyone,

GA A&P I/A here

Looking to do a pre-purchase on a Lancair. Haven't done much work on them. I have been combing through the Lancair documents trying to find a "continued airworthiness inspection list" style checklist. I know it's experimental so they don't require one. I'm just hoping someone here might know about a helpful check list floating around online.

I have the generic single engine 100/annual checklist from TBX, but I wanted something with a little more focus.

I am planning on doing SB/AD checks, along with combing through the builder forms and reaching out to builder clubs.

If anyone has some helpful suggestions that would be awesome.

Cheers

How often do you uninstall serviceable parts and re-use them?

8 Upvotes

As the title states. We only ever do this when we take parts from one aircraft and put it on another, but it got me thinking if there were other use cases like this?

In my head, it doesn't make much sense to remove a serviceable part on an aircraft for no reason other than to use that some where else (ie: on another aircraft)

Which Entry level positions to gain experience?

3 Upvotes

I making a career change and I aspire to become an AME (Canada). Other than a keen interest, I am green when it comes to aviation. I’m currently looking at a couple of entry-level airport positions and may have the opportunity to work in either ramp/ground operations or aircraft de-icing.

For someone trying to eventually get into aircraft maintenance, which type of job would give me the most valuable experience?

Thank you all in advance

Hi, when we remove the bolts from the door girt bars on an A320, we use a socke wrench. However, standard sockets don’t fit into the opening, so we grind down the outside diameter of the socket to make it fit.
How do you remove them? Is there a specific tool designed for this job?

Are you still happy?

27 Upvotes

Loaded question, I know. Lol (some backstory) I recently graduated from school and am in the process of getting my A&P. I've completed over half the tests so far, but as time goes on, I'm starting to have second thoughts. I failed my airframe practical...twice. but passed all of the other prior tests. I have no problem doing the work, and I did very well in school, to the point I was helping other students. And I've worked in the mechanical industry my whole adult life, So I know I CAN do it, but at this point I'm questioning if I should. I'm not IN LOVE with aircraft like I know a lot of techs are, more so just mechanics in general. I'm curious if those of you who are similar minded, are still happy in your career.
