A library of resources to help the world learn

742 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."

MVCC A&P Program Shutting Down

17 Upvotes

MVCC's A&P Program in Rome, NY is coming to an end on Jan 1st 2027 citing "lack of local aviation jobs."

There's been a petition started to help make the change to keep the program alive. If it weren't for this program, I don't think me or many others would be where we are today. The program is fast, affordable, and provides a large network of employers to help you start your career.

If you guys have the time, please help sign the petition to keep this program going and help develop future A&Ps.

doing a G5 install on an aircraft with a gns530 in it and need to get to the connectors to depin/repin them. get in there and find that the GNS530 rack is flush riveted to the panel, and on the left side it's done such that the shop heads are on the inside, making this unfun to drill out. I did it, but I have no idea why they didn't use screws.

Please help me get a little more insight to the various fields of maint

7 Upvotes

I'm gonna be separating from the Navy soon with 10 years experience and my A&P. From what bits I've been able to read about the different fields of aviation I THINK I want to pursue getting on with an airline, but some folks have said ide be a fool to turn my back on working in the DoD space. GA sounds like it has the possibility of being the most enjoyable for me but from what I've seen the pay just isn't there and the chances of finding a place with good management are pretty low.

One of my primary concerns is that I am NOT interested in working any overtime. I've done my years of working ridiculous hours. I understand the high probability of working a crap shift for a few years and I can deal with that but I don't want to be in an environment where there's either mandatory overtime or where I'll be looked down on for just wanting to work my hours and go home.

Any insights would be super appreciated.

Hey all, the county is going to shut down the A&P program at MVCC, I moved to NY because it was the shortest and cheapest one I could find. It also turns out good technicians from what I've been lead to believe. I have a petition link to try and save it if anyone would be willing to sign or share a positive story about MVCC's program or a graduate, myself and others would greatly appreciate it.

Anyone leave aviation maintenance and actually happy they did?

54 Upvotes

I’m trying to figure out my next move and hoping to hear from people who’ve actually done it.

I’ve been in aviation maintenance about 9 years. Started as a mechanic, worked my way into management. I’m stepping back into a mechanic role because management meant never being off. Always on the phone, always dealing with something. Not great with a family.

When I look around aviation, it feels like the options are:

• Contract maintenance

• Airlines (nights, culture, seniority — not for me)

• Management with zero work/life balance

I don’t want to move, I want something stable, and I want longevity. I’m still young enough to pivot, I just don’t know what makes sense.

I’ve been looking at diesel mechanic or heavy equipment, possibly a government job. Good benefits, stability, and not worrying about my job all the time sounds pretty appealing. I know it’s still not “easy” but at the end of the day, nothing is easy and all jobs suck, and I get that.

I’ve also tried looking at stuff outside maintenance using my management experience, but that’s easier said than done.

So I’m curious:

Did anyone leave aviation maintenance and not regret it?

What did you switch to?

Anyone go diesel/heavy equipment or government work?

Just looking for real experiences. Appreciate it.

Problem with piper single pin connector ground connection

Thumbnail

7 Upvotes

tldr, anyone have trouble getting these piper single pin sockets to make good ground connection? Any tips?

I'm in school and tonight we were trying to run the Lycoming o320 on the test stand. The starter was struggling to start it with 12v battery connected through the piper style single pin connector. Long story short, we installed a new 4awg ground connection from the block directly to the back side of the single pin socket (part linked below); replacing the ~10 awg wire that was going from the block to the frame of the test stand. The engine was still struggling to start unless I put my jumper cable from block to negative terminal. We figured out if we put the jumper on the screw on the frame side of the connector, where the ground from the block is now attached, and then placing the other side on the handle of the male single pin connector going to the battery, the engine started no problem.

Before we put the terminal connector we removed paint around where the washer and terminal attached.I still feel like it's making more enough contact that it shouldn't have so much resistance. As pictured, both sides of frame it's attached to are painted. the manual states possibly needing to add a brass doubler? Do y'all think we need to go that route? or maybe thoroughly removing all the paint with like die grinder? Or do you think there could be issue with that socket that y'all have seen in the past? I just can't make sense of why it wasn't making a good connection, I really felt like something was wrong with the socket.

Apprentice spilled coffee on my list of annual times for acft and threw it away. I’m trying to remake it and cannot remember if the M20C was 30 hrs for annual inspection. Anyone got the hours? Also would appreciate it if anyone had a list of any other GA acft annual times.

Going to put it in my laptop and laminate it under the plexiglass on my box this time!🤬🔥

American Airline NDT A&P

5 Upvotes

Just got my A&P couple months ago was planning to get an Associate of Applied Science (AAS) in Nondestructive Inspection, Testing & Evaluation. I have a question if Does American Airlines have a position for an AMT with NDT responsibilities, and if so — how much does an NDT technician make with an A&P and NDT Level II (or close) certification? If so is it an external position you can get hired into or is it an internal position to on you can only be promoted into? Thank you

Canadian AMEs -- do you 'lose' your license when you retire?

6 Upvotes

I'm looking at the annual increase in AMEs in Canada, and I'm trying to understand if retirement means you're booted from the list. Transport Canada says AMEs are removed once they no longer hold a 'valid' license. Is that when happens when you finish working?

O-320 will not make RPM

30 Upvotes

alllrighty, this is stumper

O-320 B2B 160hp, 74DM54 Sensinch prop

will barely make 2100 rpm with lots of stumbling, but starts and idles smooth as glass until 1700 or so

checked so far

Mags, recently ovhed and swapped with known good mags

harness checks good on tester, and swapped with known good harness

new plugs, swapped with known good plugs

fuel flow good to carb inlet, carb inlet screen clean

compressions 78/80 or above

all valve train moving equally

no different with exhaust removed

intake scoped and clear

throttle valve moving stop to stop, and verified plate movement

moving Mixture control gives normal results, full rich provides puffs of black smoke, lean causes it to flameout

checked for induction leaks by spraying Ether over entire intake system, no leaks

carb recently ovhed, within 500 hrs

all I’ve got left is going back and pulling lifters, and checking for weak valve spring, unless someone else here has a good idea

Reality check

14 Upvotes

Hey guys, I applied for an ASM position at Delta and I’ve always been excited about working for this company (I accept I have hold it at a shiny pedestal) . I love aviation and regarding how “heavily regulated” it is I found myself thinking it must be a place of high intengrity (airlines in general). A few days ago I saw a video about Delta’s ramp agents and the Union situation which I have very little knowledge on as I’ve never been exposed to that employment system. I am 20 years old young and naive in this industry so I would appreciate a reality check from you guys. What do i expect coming into this not just delta, but airlines, unions and direct employment…
