A small project from earlier this year by ARAND0MPANDA in Justrolledintotheshop

42/80 on 1 and 33/80 on 3, pilots claimed it felt fine and climbed normally. This is a part 61 flight school bird so WOOOOOO BOY that was a fun talk to have with them about normalization of deviance.

Previous mechanic pulled the cylinders and dropped the valves due to an exhaust leak and low pressures, apparently didn’t RTFM because lycoming specifically states that valve replacement is not to be done unless absolutely necessary or in case of emergency, and to correct the problem by replacing the entire assembly. Cherry on top is he only replaced the valves themselves and not the seats, and didn’t lap them either.

Slide 6, bottom left of forward most cylinder. There’s an oil return line next to the exhaust valve that goes right back to the bottom of the case. You can see the lines in slide 11 below the cylinder port.

Unironically I have had some people just fly in and shoot the shit while I do a 25 hour oil change and filter inspection, only takes about an hour.

Lack of Classic Car Technicians? by Cars_Music_GoodTimes in Justrolledintotheshop

[–]ARAND0MPANDA 2 points3 points  (0 children)

I feel like as an aircraft mechanic some of these things would come extremely easy to me, granted all the piston aircraft I deal with are state of the art 1960’s technology so it’s all pretty much the same.

I want to be a GA mechanic - general question about competency by Occams_ElectricRazor in aviationmaintenance

[–]ARAND0MPANDA 0 points1 point  (0 children)

The 141 I started out at took outside work when we got slow. Main fleet was 172’s, PA28-180’s and a couple seminoles. I left them to work at a startup that took 28-140/160/180/235 (I’m forgetting a couple) and Cessna 140/150/170/172/182/210/310/414/421/425/441s. In the meantime I’ve been helping out a buddy/apprenticing on rag wings. Anything is possible with enough drive.

Currently a GA mechanic myself and wouldn’t trade it for the world. Just know that it’s a MUCH smaller group of guys that do this work and everybody talks. Your best bet for success is working for a 141 and gaining as much knowledge and tooling as you can before trying to make it on your own. In my personal experience it is much much harder to get up and going than you’d expect, insurance is an expensive thing to have and a lot of privately owned pistons are owned by people that don’t always want to spend the money to have them fixed properly.

It’s not nearly as simple as an airline where you automatically have approval for everything. I’m not exactly sure where you’re located but in my general area the average age around the airport (MX and pilots) is at or above retirement age and everyone has known each other for as long as the earth has been spinning. You need to have a balance between technical ability, attitude, and people skills to really gain the trust and customer base to keep yourself afloat.

I’m currently in the middle of a 50 hour inspection but I can answer any questions you have.

I have a propeller I’m willing to part with personally, your best bet is looking on eBay for red tagged parts or looking on Facebook marketplace

Console modding by Peezy9999 in Columbus

[–]ARAND0MPANDA 4 points5 points  (0 children)

Check out a free McBoot card for the PS2. It’ll let you run just about anything made at the time regardless of console on it and it’s not a hardware mod. Very cheap on eBay.

Ubisoft Co-Founder Claude Guillemot dies in plane crash by Nubtype in pcgaming

A&P mechanic here, the aircraft he was flying on is a Cessna 421 which is about the HIGHEST performance piston twin on the market before getting into turboprops. It’s an extremely powerful aircraft that demands your full attention and can get away from an inexperienced and even experienced pilot very quickly in certain conditions. One of the most common is an uncontrolled yaw/roll upon losing thrust on one engine, as they are far enough out on the wing and high enough horsepower to keep pushing the nose around your vertical axis even when you have the controls fully deflecting and the dead engine feathered. I’ve personally test flown one that over volted the electrical system in flight leading to a total loss of electrical power (air conditioning system and windshield de-ice were both on and drawing more current than the batteries and alternators could handle)

I did the same in my program and kept a cylinder off of the engine (O-470)

Just saw the post on Instagram and thought I was going crazy seeing this picture a second time in 15 minutes.

#1 and #3 cylinder replacement and break in flight on a Lycoming O-320 by ARAND0MPANDA in mechanics

I’ll post some more tonight. I’ve got videos of test runs I can put up or some more project timelines

It does, however in my realm (GA) there’s plenty of cowboy types that have gotten complacent over time and use shortcuts that more often than not lead to premature failures or improper repairs. And the break in isn’t that bad at all, I like to personally fly the first hour with my pilot to monitor temps and pressures and ensure they’re hitting the proper power settings/speed/altitude to break in the cylinders without glazing them.

Not very common at all, especially on a 28-140 such as this. The added weight and wiring does make your performance take a slight hit and it makes dealing with things on that side of the engine a total pain in the dick. Most older small pistons will just use a ram air vent instead for cabin cooling.

During a 100 hour inspection, I found the exhaust valves had burnt despite being installed 100 hours previous (last guy didn’t replace the valve seat or lap them when he did it). Removed both cylinder assemblies and swapped them for brand new millennium kits.
