A library of resources to help the world learn

773 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."

When a task card calls out flush lubrication instead of a Zerk, is this typically done with a standard grease gun using a flush-tip adapter?

12 Upvotes

When a task card calls out flush lubrication instead of a Zerk fitting, is this typically done with a standard grease gun using a flush-tip adapter? The grease point appears to be a countersunk vent that accepts approximately a 1/8-inch tip. I understand how the Zerk type work, but not exactly sure about the flush type.

Need advice on how to get my a&p

2 Upvotes

Im in a bit of a predicament, im 19 and have been working and saving up money for the past year, i have wanted to be an aircraft mechanic for a few years now, since i was abt 16. But its really difficult to find a way to comfortably do it, because my options are slim in tampa. I live really close to NAA, but theyre super expensive and idk if its worth it, i was planning on going to traviss tech, but thats over an hour commute each way and idk if im ready for that, it seems very grueling.

So im looking for any advice, because this is keeping me up at night and my anxiety over the future is just going crazy. Im willing to move just for the licence at this point.

Nightshift Walkaround flashlight

39 Upvotes

For the past 2 years my primary walkaround flashlight has been the Olight Baton pro 3, lately I’ve been noticing it struggles to illuminate the top of the 777 rudder and its battery life has fallen off significantly, I also hate the magnetic charging as I’ve found it to be somewhat fickle.

I’ve been looking in to the Nitecore EDC 17 and 25.
Does anyone have any experience with those 2 flashlights in a flightline environment?

I would also love other suggestions I’m trying to keep the budget around $75-$90.
Thanks!

Studying O’s & P’s

13 Upvotes

I know this question gets asked a lot, but I’m having a hard time finding the right resources, so I figured I’d ask.
I passed all three of my written exams and now I’m starting to prepare for my oral and practicals. I feel like I’m overthinking it, but I just want to make sure I’m studying the right material and not wasting time on things that won’t help me.

What are the best study guides/resources for the oral and practical portions? I’ve seen a lot of people recommend Jeppesen is that the go-to? Are there any good Quizlets you recommend, and if so, which ones did you actually use and find helpful?

Are there any books or guides you would recommend purchasing? I just wish there was a clear guide that showed what I should focus on and what kinds of questions/tasks to expect.

Any advice would be greatly appreciated. Good luck to everyone currently studying for their O&P!

Are insulated tools important for electrical safety?

33 Upvotes

Electricians are encouraged to have pliers and screwdrivers with fancy insulated grips to provide more protection against electrocution compared to normal dipped handles. I mean like those Knipex tools with the red-and-yellow handles rated up to 1000 volts. A commercial jet is full of high-voltage wiring, and I assume there's no less of an electrocution risk compared to a house or building; in either case we can open the circuit breakers, remove external power, and turn off the batteries while working, but unpredictable shit happens. Yet I don't see any coworkers at the base rocking insulated tool sets. Is the risk really that negligible, or do people just live dangerously because they don't want to pay the extra cash for insulated tools?

EASA Part-145 ePub

12 Upvotes

I recently found myself needing to look up EASA Part-145 quite a bit while I was away from my desk, and reading the PDF on my phone got old pretty quickly. So I converted the current Part-145 (including the AMC & GM) into an EPUB so I could read it on my Kindle.

I figured some of you might find it useful as well, especially if you regularly reference Part-145 on the go.

The content itself is unchanged. It's just the official document reformatted for e-readers. If you notice any formatting issues or have suggestions for improvements, let me know.

Disclaimer: This is an unofficial EPUB conversion of the official EASA Part-145 (Annex II) publication. The content has not been modified; only the formatting has been adapted for e-readers. The official EASA publication remains the authoritative version.

I'm currently studying aircraft maintenance and stumbled upon that website. Useless to say I'd LOVE to buy one of those but I'd rather make sure it's not a spam before.

Anyone here knows or ordered something from this website ? Or even got one of those DIY turbofan ?

Thank you !

Orientation

11 Upvotes

This may sound dumb, I start a contract next week and they informed me to first 4 days are orientation and I’ll bring my tools in after that. My main question is what am I expected to wear during orientation?
I’ve only worked on the military side of aviation and did not attend A&P school so all I know is to wear my uniform and boots. I’m assuming a backpack with my forms is typical to bring but I’m not sure if work attire (boots/utility pants/tshirt) or something a bit nicer (khakis/nicer sneakers/polo) is expected.

Anyone can send something into the sky

0 Upvotes

Saw an epitaph of a space shuttle engineer that said "Anyone can send something to space. But here lies the man that brought them back."

I made my own modification out of it:

"Anyone can send something into the sky. It takes a real mechanic/pilot to bring them back".

Hope you like it.

forceps

I've had the same pair of forceps for years, and they finally broke. I used to find great ones at flea markets, but those seem to be few and far between these days. Where do you go to find a good-quality pair?

People who've dealt with AOG, what takes up the most time in fixing the aircraft?

53 Upvotes

Marine engineer here. I know what it's like when something critical breaks and the part you need is an ocean away. Lately I've been wondering how its managed in Aviation (since I am a huge avgeek)

Everything I read says a grounded aircraft bleeds tens of thousands per hour, and that a big chunk of the downtime is waiting rather than working. Waiting for the part, the paperwork, the right person with the right stamp to show up.

Before I blindly believe what the articles and literature say, I'd like to hear it from people who actually live it:

  • In your worst AOG, where did the hours actually go?
  • Ever known the part (or a qualified person) was sitting nearby (another airline, another hangar, another MRO) but you couldn't touch it? What happened?

Seeking perspectives of AOG desk managers, MCC controllers and AMEs.

Ramp agent->maintenance.

Hey, I just got a job as a ramp agent in Seattle, and if I work for six months I can maybe get an apprenticeship for aircraft maintenance. Should I be looking forward to it? I’m interested but is the pay good after I get my A&p? 100k?

Travel Anxiety?

8 Upvotes

For those that have to travel often for the job, so you experience any travel anxiety? If so, what helps? For context, I'm working at an MRO so I don't have to travel too often for work, but recently I've been having to travel more and my anxiety around flying has gotten pretty bad. It's gotten worse since I've had my daughter a year ago, but I figure all of life's anxiety gets worse once you have kids.

Overall I feel crazy since I know aviation is safe, but my nervous system can't seem to agree.
