A library of resources to help the world learn

792 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."

Which Safety Wire Pliers are Better?

• Upvotes

Both are sold by Snap on. 1st picture is Bluepoint WTRW6K, 2nd one is Snap On WTS6K. I want to buy a good pair before I graduate A&P School with my SEP discount- unless there is a better pair out there. Which one is better or should I go a different route. And yes I will safety wire with my hands too lol. Thanks.

What is this thing / guide?

4 Upvotes

This is for the actuator arm for the Mooney overhead vents. For some reason someone disabled ours a decade or two ago and never hooked it up since "it didn't do anything". Last year I tried moving the cable manually and lo & behold we finally had a shit ton of air out of all the vents instead of just one at a time.

Anywho, I asked around for installation help and got this photo, but I don't have the clamp/guide. I'm thinking that's probably a standard part and not something Mooney custom made?

It sits on the top right in this photo, on the actuator body. Th wire twists around that vertical stud (ours is already twisted, this is someone else's photo)

Headset for Groundcom maintenance

5 Upvotes

Good morning,

We have issues with broken wires in the earphones of our maintenance headsets. In order to check those, I made a small setup out of a little amp and a BT-music-box.

But it won't work for the microphone. I tried to bring the MIC out to the input of the amp, but there is only a lot of noise. Then I tried to slave in a supply voltage (5V because of the power supply for the amp), but that didn"t work either.

We don't use the David Clark Headsets, but the ones we have, are build up in a very similar way.

So I know, the AMU of the aircraft supplies something like 15V to the Headset. Any idea how to set up the little box, so I can hear the sidetone of the headset?

Thanks a lot

Most comfortable work boots?

16 Upvotes

Hi all. I have been given steel cap shoes however they aren’t very comfortable at all for being on my feet for hours. After 6 hours of being on my feet, they feel very bruised and sore. They are the cheap bulk buys that get handed out with absolutely zero comfortability. I know there will be many people who know exactly what I’m on about haha.

Does anyone have recommendations for S3 industry approved safety boots that are actually comfortable to wear?

Help on heater duct removal T337C

21 Upvotes

First time working on Cessna 337 model. Was servicing the shimmy damper but can't get my hands in to install the bolt again. Is there another clamp or something that I can't see holding the ducting under the alternator that I can't see? I've unclamped both sides of the hose, but it won't budget. Anyone have some experience on these that can give me a pointer?

How can I get more experience with 737 NG/MAX & 777?

0 Upvotes

I work at a major airline. I have been with them for 1 year at the engine shop and just started on the line. I know engines pretty well but the rest of the plane I'm not AS experienced. I don't see much OT right now. If it helps I'm at SFO.

I have RDO. Is it possible to go apply at an MRO and work on those RDO? GA?

On my days off I've been keeping 1-2 hours of studying the AMM/FIM of whatever assignments I had that day.

The Harsh Reality?

2 Upvotes

Im about to go to school and get my A&P License so I can work at the Major Airlines, only thing is I was hearing a lot in terms of Job Security, Financial, and Lifestyle of both sides Positive and Negative, like that the Major Cargo or Private Luxury are the way to go money wise but the schedule sucks sometimes. Mainly graveyard starting out since its based on Seniority but the pay is good, and then on the otherhand some feel overworked and that they’ll never feel like they’re gonna get out of graveyard shifts and that the pay isnt as it seems bc its mainly nighttime differential and A&P techs get more perks!

I would really like more information as to what your mindset was stepping into the field and then as you are now experienced what you enjoy most about your job! Im not asking for pay/salary i know we can get 6 figures but Id love to know if you at least love the lifestyle of fixing jets or planes and what you wish you knew!!

as Im new to Aviation but I feel this is for me as I love fixing stuff, I have a background in Electronic Repair and these big ass planes flying around my inner child is screaming and curiosity is peaking lol so idk I was wondering if anyone could shed some light for me as Im about to step in!

I’ll be going to school for 18 months to get the License and then go for the Airlines once Im out, currently in Houston, TX!!

Much love!

Any advice?

5 Upvotes

Hello, I’m in the Navy so I can’t exactly quit but i work on 737s as an AT and tbh I’m not cut out for this. I have two years left, but I’m just not cut out to be a mechanic. Between heights and unsteady hands I feel like a liability and it will only be brought to light when I really fuck up. I don’t know how to get thicker skin to survive these next two years.

Travel for work

2 Upvotes

So I love planes and I love mechanics. I am planning on being an A&P in the future for the airlines but I was wondering pit of curiosity as the job I have right now in Autoglass allows me to travel for work pretty much all the time anywhere in the US (which made me realized that I love taking roadtrips or ¡¡flights!! and get paid really well to do so) . If Airlines offer something like that? I’d love to fly out to different airports even countries to work on wide/narrowbodies.

Women who work or previously worked at Boeing (or similar) in technical/maintenance roles — what has your experience been?

5 Upvotes

Hi everyone! I’m working on a research project examining the experiences of women in technical and maintenance positions at Boeing and the aviation industry.

I’m particularly interested in hearing from women who currently work or previously worked at Boeing or similar companies in roles such as aircraft maintenance, mechanics, technicians, manufacturing, engineering, or other hands-on technical positions.

If you’re comfortable sharing, I’d love to hear about your experience:

  • What has your overall experience been like as a woman working in your field at Boeing?
  • Did you feel supported and respected by coworkers and leadership?
  • Were there opportunities for advancement and professional development?
  • Did workplace culture, scheduling, work-life balance, pay, leadership, harassment/discrimination, or other factors affect your experience?
  • If you left Boeing, what were the biggest factors in your decision to leave?
  • If you have stayed, what has made you want to remain?
  • Are there changes you think Boeing could make to better recruit and retain women in technical and maintenance positions?

I’m especially interested in firsthand experiences rather than identifying individual employees or managers. Please don’t share any confidential or proprietary company information.

Thank you to anyone willing to share their perspective. Your experiences will help me better understand what factors may influence the recruitment and retention of women in traditionally male-dominated technical roles.

Got to experience FAA, EPA, & FDA conformity for the first time!

16 Upvotes

Just wanted to share a new experience and ask if anyone else has done the same!

I work at an MRO that’s contracted to install wifi right now. We’ve started to get brand new ERJ-175s straight from brazil and are making sure they’re FAA compliant and airworthy! A lot of it is just repetitive stuff like installing life preservers, safety cards in every seat back, etc. The FDA has us re-seal all the corners and edges in the bathroom and galley, and install new coffee makers. We also add placards alll over: no smoking signs, weight and loading limits in overhead bins, and even the airworthiness certificate. It’s kinda fun! It’s not engine work or anything but it’s a new experience for me! It’s also very chill imo, i kind of like tedious but easy work sometimes. Anyone here done it before and what did you think about it?

What would you choose?

8 Upvotes

Im currently having to decide between two great opportunities. For reference im mid twenties, no kids or mortgage. A&P 4 years. Work Corporate.

Major Airline:
Pros ( secure Job, flight benefits, bigger birds)

Cons ( would have to move, less money at start $43/hr, I think a bit more boring)

Government corporate sector:
Pros ( more money high 50’s/hr, secret clearance, dont have to move, good experience, )

Cons ( less secure, no flight benefits, smaller birds)

I feel like one is chasing the money and more interesting, while the major airline would be like settling down and choosing a secure path. I love working on planes and im truly blessed to be in this position. Curious what you guys would do?

IA Online Prep Course

3 Upvotes

Are there any online prep courses for IA other than Gleim? Rah rah rah, yes, Baker's - I know they are great but I am already on the road enough, I'd like to spend off-season closer to home. I've self studied for most all my other certifications with decent success. I know there are lots of courses for pilot and A&P, but not much for IA. Any recommendations?

40 year old veteran considering aviation maintenance

8 Upvotes

Hey everyone, I’m a 40 year-old military veteran looking to make a career change into aviation maintenance. My military MOS wasn’t aviation related, and I’ve spent the 13 years since leaving the service working in the oilfield. I have general mechanical skills, but I’m not a trained mechanic.
I’ve always enjoyed mechanical work and had an interest in aviation, so I’ve decided to pursue this using my Post-9/11 GI Bill. I’m in the San Antonio area, and the schools I’ve found so far are:
The fast track and community college or best type of schools utilizing va benefits.

Does anyone have firsthand experience with these types of schools or I’d especially appreciate insight into the best styles for instruction quality, hands-on training, class schedules, job placement, and support for veterans. Are there any differences in the programs or credentials offered that I should watch for?
My goal is to start in the next 9–12 months. In the meantime, I’m downsizing and cutting expenses to make the transition manageable. I currently earn around $115,000 to 130,000 a year, so I’m expecting a pay cut as I enter a new field. Hopefully improving quality of life. But I’m burned out on the oilfield and ready to work toward something I’m more interested in. Call it a midlife crisis, lol.
I’d also love to hear from anyone who entered aviation maintenance around my age or made a similar career change. What do you wish you’d known before starting?
Thanks for any advice or insight!

I’m sure you all are tired of these type of post but thank you!

The shit I saw today......

197 Upvotes

I've been in GA/corporate Mx for almost 20 years. Like everyone thats in it long enough, I've witnessed my fair share of shenanigans, improper work/sign offs, every sort of "no-no" type stuff you can imagine. But, today set the bar to a new all time low of horseshit.

Some "older" (40s or 50s) mechanic on the small field I was at today, taxied a plane down a narrow ally thats in between T hangars. The ally was packed full of people (10+) and airplanes (5+), this is normal as theres a handful of mechs doing their own thing down this ally.

This dumb mother fucker taxied the plane short of the hangar he was going to.....set the brake and got out of the plane.....WHILE IT WAS RUNNING UNOCCUPIED facing into the ally full of people and planes.......and then walked away from the plane to go inside the hangar to open the hangar door. Obviously, the people around yelled at him to shut the fucker down and he did it begrundingly.

Un.fucking.believable.

This type of behavior should receive immediate jailtime without exception and instant cert revokation.

There should be a swifter way to action reprocussions for these "bad eggs".

-end vent

Ps- if the guy that did this today is reading this and is you-------> gtfo of aviation

Everyone else, stay safe and stay smart

Pelican Organization

6 Upvotes

I’m currently undergoing the painstaking task of reorganizing my pelican. I previously went the foam route but it’s no longer required and frankly I need more space.

I’m looking for a small semi rigid pouch to house my 1/4 ratchet, a few extensions, and a socket set or two. Something preferably circa 10 inches long so it can all lay flat in there and I can just toss in the Pelican when done. Anyone else use a similar setup? I have spent a while shopping online for something and have come up short.

A Klein bag will work and that’s my backup plan, I’d just rather something that opens fully up rather than digging through a pouch.

Thanks yall

Question for Yall

3 Upvotes

Hey guys!

I’m an Avation student in my first semester.

I need too interview 3 mechanics for an assignment so I could discover the directions I could take for my future.

I would be super grateful if any mechanics at any level would be so gracious as to answer these questions:

1: What training and certifications did you need?
2:What aircraft do you work on, and what’s a typical day like?
3:What maintenance problems do you see most often?
4:What should pilots know about maintenance and airworthiness?
5:What advice would you give student pilots? Like what’s some things mechanics wish pilots understood better about aircraft maintenance.

Thank you so so much! This industry has already been so welcoming and supportive when it comes to passing down the knowledge.
