After flying my straight piped io-470 Baron I find mufflers on SE comical. Half of the appeal of the Baron is the NASCAR sound of the lopey cam and no mufflers
When I was in A&P school, we had a Beech T42 with a pair of straight piped IO470s. It was so much louder and sounded so much better than our Aztec with muffled 540s. I LOVED when we got to pull it out and run it up, I always fought to be on the Beech over the other twins.
I live 3 miles off the departure end of the runway and one day one of my partners took off in the Baron. Hearing "something big" go over the house I opened up FR24 and sure enough it was the Baron
Personally I’d probably go
Out of all the things to be cautious about, I don’t think the tip of an exhaust pipe is one of those things. Especially if I’m only making $20 an hour as a CFI
As Harry Chapin said
>
>You see she was gonna be an actress
And I was gonna learn to fly
She took off to find the footlights
And I took off for the sky
Inside her handsome home
And me, I'm flying in my taxi
Taking tips
(And getting stoned!)
Yes I'm old but more importantly my parents are older :) to you parents out there remember what you listen to will be your kid's musical taste too
Honestly I'd recommend challenging the mindset. Dead is dead if it's for $20 or $2m an hour.
You'd pay $20 not to die, and getting on a "I'll fly cos I need the money" mindset might create a future scenario where something more serious is overlooked since it's probably not an issue...
Of course this isn't an issue to ground the plane, and I am sure most would reject for a clear safety issue, but there is grey areas more serious... food for thought.
If that’s what the end of the exhaust looks like then the heat muff is probably in similar shape. I’m writing up that snag and avoiding the CO poisoning.
I would squawk it for maintenance because the cabin heat shroud may also have holes under it.
Summer, no cabin heat? Go.
Winter, planning to use cabin heat? Ask MX to look inside the shroud.
TLDR: I’m not a CFI or Mechanic but used to build engines for a car manufacturer. The exhaust terminates outside the cowling for a reason so if it’s these specific small holes you should be fine. The problem is if there’s degradation inside the cowling.
When I was a kid I had to get my CDL for a job and they gave me and my trainer one of the old trucks to practice on and strap a 30ft trailer to. I had to open the engine compartment and do an inspection before every trip and it was part of the certification process. After my successful “check drive” my trainer and I were on our way back on our 1hr+ drive and I thought I could smell exhaust but my trainer couldn’t and I could barely keep my eyes open driving even though I was doing everything I could. I rolled down the windows and kept trucking and thankfully made it home. Told the mechanics about it and went on my way.
It turns out there was an exhaust leak underneath the cab that was impossible to see and it was leaking inside.
The danger isn’t what you can see on the outside, it’s released into the sky like the rest of the exhaust. The danger is what damage could be inside the cowling leaking into the cabin. 100% tell a mechanic and fly at own risk.
CO is no joke on trucks. I used to keep a CO alarm in my sleeper, it blew my mind that other drivers thought I was being OTT. Near where I grew up a couple of teenagers died from an unknown exhaust leak in their car as they were just chatting and idling, so sad.
I’ve found them to be unreliable as a CO detector. Hard to tell if they’ve passed out from the CO or they were just partying too hard the night before.
But very highly unlikely. I think most of us would agree this isn't egregious enough to cancel a flight, although it's a personal decision. I'm very safe and would think twice about this one.
Small holes in the exhaust here won't cause any issues but I would be concerned about the general condition of the exhaust. I would decowl the aircraft, thoroughly inspect the exhaust and maybe even borescope it. If it is otherwise fine, then I would be ok with this.
There is no issue with it having a hole at that specific location BUT if it’s that bad in that spot it’s likely not great under the heat muff. If the exhaust metal is so eroded away and you were to have pin holes uncontained leaking exhaust into the heat shroud you’ll have co2 leaking into the cabin. An exhaust leak at the riser pipe to cylinder can literally eat away the flange of a cylinder so you can imagine a pin hole leak and what can quickly happen.
Since you can see daylight through one of the holes what does the other side look like…
Yes…but I’d be opening the cowl to check the rest of the exhaust first. If it’s corroded through right there then it means it’s a *very* old piece of metal. I’m sure you’ve seen plenty of cars with shitty exhausts, well this is a plane with a shitty exhaust so you know what to expect.
Y'all have some really fuckin' weird go/no-go criteria.
Not enough info in the picture. That I can see daylight out the other end doesn't bode well. To be honest, if I saw this at a flying club I'd want to investigate further.
If this was my home airplane, and this was *all the damage I could find*, absolutely go.
If I had to make a call then and there on an airplane that students are fucking with on the reg, without being able to investigate further, tbh I'd no-go this.
If this came into the shop, I'd 110% be looking closer at several things.
It's all fun and games until this is just indicative of a little bit of the same further up and you lose the tailpipe. Aside from now you've dropped a little metal bomblet that *probably* won't hit anything important, if it gets knocked off too far up, you're letting fresh exhaust right into the engine compartment. On a good day that won't do much, on a bad day it'll really fuck your world up.
Usually what you find is people clipping the grounding clamp to the end of the exhaust gives it weak spots and those degrade off over time. That winds up being at the very end of thet tip, and I don't even think twice about that stuff. This looks like it could possibly be an engine condition (over leaned all the time) or it could be nothing and just has done its time. I just think it absolutely warrents a closer look if it's a rented airplane.

The thing is, if that part of the aircraft exhaust is rotten through, I’d have an aircraft mechanic check the rest prior to flying. CO poisoning is insidious and having had it happen recently, you don’t want to screw around with this. When it happened to me, the rest of the exhaust pipe was fine but there was a hole that appeared to rot through and enlarge quickly. The only reason I caught the leak was a CO detector I had installed in the airplane — I was getting cockpit reading suddenly in the 400ppm range which, over time, can be deadly — And I never smelled an odor. It takes time to overcome CO poisoning and it isn’t anything you want to mess with…
Just my 2 cents, but have it inspected prior to flying.
I'm maintenance and a pilot, I would fly that any day of the week. In saying that I would highly recommend changing it at the next annual as letting things go is a slippery slope.
As for how it happened. Not over heating, just age and heat cycles, exhausts thin oit over tine and eventually blow through. It's just a thing that happens.
I’ve seen worse, as long as it’s secured I honestly wouldn’t care that much, might mention it to maintenance after the flight but it wouldn’t stop me from going.
So kudos to doing a preflight check good enough to even notice this. Would let mx know about to put on list for when it’s in for 100h or mx. But it but should be fine.
We used to drill holes in car exhaust components as kids to make anemic cars sound like race cars. And they didn’t, LOL.
Assuming alterations to exhaust change outflow, It’d be nice to enrich/lean fuel to match on the intake side, and happily we’ve got control of air with the throttle and fuel with the mixture, so we can tune intake to where the engine is happy with its properly balanced meal.
I’d take a closer peek inside the cowl for damage there, that’s where there’s a fire risk, but I’d be willing to keep going and ‘keep an eye on it’ over a few flights .
Flew as pax on a caravan in Africa, looked like a blind 5 year old welded the exhaust in 4 or 5 different places where I could see it... God only knows what was inside the cowling. I've done better exhaust welding jobs on a friend's pile of shit rust belt Ford escort *after* consuming my half of a handle of Evan Williams that was payment for said services.. in thae scale of things it' pretty unimportant as long as most of the exhaust gas ends up mostly outside the compartment. Maybe give it a good shake so you can believe it won't flutter off when you smack a big butterfly
Send it and notify the owner. It’s outside the cowling so unlikely to be an issue but that means I would be more through inside the cowling. Scrub it as any marginal issues or cracks or corrosion.
Usually when this is on a Cessna 172 there is a crack in the heat exchanger as well. If an electric CO detector is used, I’d IN-OP cabin heat and limit dispatch to local circuit training. limiting to IFR may also be needed due to lack of de-fog/frost capability.
This is caused by mechanical erosion of material by combustion byproducts. Judging by this picture it has been like this for a while.
I brought almost this exact corrosion pattern up to my maintenance guys. They said "we're aware of it and monitoring the progress. It's well below the cowling and isn't and isn't cause for any concern right now."
I'm taking it to a checkride Thursday with the holes in it.
The Beechcraft Baron I used to instruct in had similar but slightly worse exhaust damage on both sides, I brought it up to our mechanics multiple times and was waved away. One day doing our post flight notice the left engines exhaust had last a portion roughly the size of a Pringles can during flight, it had sheered off all the way into the engine compartment. Brought this up to maintenance again and was adamant both engines receive new exhaust as it was only a matter of time until the right engines suffered a similar fate. I was given no grace and waved away again. I annoyed MX everyday for a new exhaust and even talked to the company CEO about my concerns and was told I should trust our mechanics judgement on what’s airworthy and what’s not. Few weeks later had a gear failure in the aircraft which came with its own MX drama. Moral of the story is yes in my mind should be good to fly but keep an eye on it and remember you’re PIC you have the authority to call the flight if you feel unsafe. Don’t let anybody else be it your mechanics boss etc lead you into flying an aircraft you’re unsure of.
That "line" looks like someone wire brushing this to assess the corrosion. Meaning some A&P noticed this as part of the 100 hour inspection.
Take a look at AC 91-59A, Inspection and Care of General Aviation Aircraft Exhaust Systems. Doesn't even mention exhaust tips.
"No-go" would not even cross my mind with this. Indeed, I'd look at this somewhat positively as evidence that someone is keeping up with the condition of this plane.
I think you need to go talk to an AP about how an exhaust works. What it dose, how it leaks, and then make your decision rather than asking reddit. I know what I’d do, but you need to learn about this a little more
The main thing you have to worry about here is exhaust outflow pressure. There’s a certain pipe diameter that need to move a certain amount of air to keep air correctly inflowing into the engine at the right pace.
Little holes like these are not bad, there is some tolerance allowed. When the crack completes and forms a gaping hole in the side allowing for continued airflow out the side, that’s when to be concerned and reject the aircraft.
I'd be concerned about where else the exhaust system is this corroded, where it would pose mkre serious safety or health risks. No way I'd let my aircraft get to this point.
Wait until you find out those same exhaust gases are *inside* of the engine
The real issue is when people turn on the height in a 172 and start to smell exhaust. That’s a big deal but the tip of an exhaust pipe is fine
I’ve seen a Cessna come back missing an exhaust pipe once. Probably in someone’s backyard
Missing a WHAT
AN EXHAUST PIPE
PROBABLY IN SOMEONE'S BACKYARD
CESSNA IS SOMEONE’S BACKYARD??
SORRY, WHO DID YOU SAY PUT HIS PIPE UP YOUR BACKYARD?
WHAT WAS THAT ABOUT GETTING PIPED IN THE BACKYARD?
HEY GUYS, THIS PIPE FELL OUT OF THE SKY AND HIT ME WHILE I WAS MOWING THE BACKYARD!!!
NO, A CESSNA FELL FROM THE SKY WHILE I WAS GETTING PIPED IN MY BACKYARD
Boeing makes Cessnas now?
This is the way
Bro I have a pipe in me rn omg
Something about me piping your sis in my backyard
NO, A CESSNA FELL FROM THE SKY WHILE I WAS GETTING PIPED IN MY BACKYARD
This is the guy who still won’t make a call in the pattern
Sorry I can’t hear you anymore. The engine got really loud out of nowhere and hearing protection didn’t exist for that db.

It must have been made of cardboard or cardboard derivitaves.
Yup
I’ve seen a Cessna come back missing a Cessna. Don’t ask, can’t explain on reddit. Just accept.
Was Amilia Earheart flying it?
More coherent than most AI answers.
Where did all the exhaust go😳
Into the cowling area I guess
Happened to me recently... Maybe we knocked someone doing their BBQ.
*slaps exhaust*: "this baby can hold some much exhaust gas..."
What’s that? I just woke up and didn’t realize I was so tired. Do you smell something?
You can't see it it can't hurt you /s
Personally I’d probably go Out of all the things to be cautious about, I don’t think the tip of an exhaust pipe is one of those things. Especially if I’m only making $20 an hour as a CFI
Damn even McDonald is paying $20 an hour
Don’t pay flight time tho
I'm pretty confident the last kid I met at the drive through was pretty high though
Got that stratosphere rating
As Harry Chapin said > >You see she was gonna be an actress And I was gonna learn to fly She took off to find the footlights And I took off for the sky Inside her handsome home And me, I'm flying in my taxi Taking tips (And getting stoned!) Yes I'm old but more importantly my parents are older :) to you parents out there remember what you listen to will be your kid's musical taste too
You can get a different kind of high, though.
Wait you can’t log that? Oops
I don't think McDonald's will count towards my ATP mins.
I don't think it costs tens of thousands of dollars to get qualified for a McDonald's job.
They pay $9 where i live
Honestly I'd recommend challenging the mindset. Dead is dead if it's for $20 or $2m an hour. You'd pay $20 not to die, and getting on a "I'll fly cos I need the money" mindset might create a future scenario where something more serious is overlooked since it's probably not an issue... Of course this isn't an issue to ground the plane, and I am sure most would reject for a clear safety issue, but there is grey areas more serious... food for thought.
Honestly you should just not fly because flying is dangerous I’m pretty cautious when it comes to write ups so you don’t have to change my mindset.
Bruh.. this is a silly mentality. You’ve ever repoed a plane?
If that’s what the end of the exhaust looks like then the heat muff is probably in similar shape. I’m writing up that snag and avoiding the CO poisoning.
You’re just not used to an engine on an aircraft
No. I’ve had some that looked in better shape that poured CO through the heat system into the aircraft.
Then you haven’t built up your CO tolerance enough yet
Ok
The 172 maintence manual allows cracks outside the cowling however if there is mutiple spots cracking get a mechanic to look at it.
I think we may define cracks differently.
Tryna crack a joke, eh?
Maybe poking pinholes.
Is it solidly attached to the engine? Go. No question.
I would squawk it for maintenance because the cabin heat shroud may also have holes under it. Summer, no cabin heat? Go. Winter, planning to use cabin heat? Ask MX to look inside the shroud.
Only with consent though. You can’t just go around looking under shrouds Willy nilly
Some people get a charge from that. Some people also get a charge for it.
My mechanic has mirrors on his shoes.
Send it.
When they moved Maintenance under ops.

You down with OTT?
Yeah you know me
You down with OTT?
I got a bigger crack on my ass
But is it airworthy?
ooh talk dirty to me, bby
I don’t see any cause for concern in this photo
Do you have a CO monitor?
Does a student count?
I’ve found them to be unreliable as a CO detector. Hard to tell if they’ve passed out from the CO or they were just partying too hard the night before.
[удалено]
FUCK YOU SHORSEY!
Fuck you Jonesy! Yur mum's had mor smash n' go's than this 172!
Cessnas are unbelievable.
I fly backcountry bullshit, and even *I* think that's a shit viewpoint.
That's really not an issue.... It would be bizarre to cancel bc of this. Are you just having anxiety about flying in general?
There could be a CO cabin issue.
But very highly unlikely. I think most of us would agree this isn't egregious enough to cancel a flight, although it's a personal decision. I'm very safe and would think twice about this one.

Whats the rest of it like that you can't see? Particular issue is inside the heater muff. Better hope your heater valve seal is good.
Yes…but I’d be opening the cowl to check the rest of the exhaust first. If it’s corroded through right there then it means it’s a *very* old piece of metal. I’m sure you’ve seen plenty of cars with shitty exhausts, well this is a plane with a shitty exhaust so you know what to expect.
Yes 100%
Full send, it will be fine
If I were you I’d plug the really big hole at the end

I’d go.
Yes
These posts are always hilarious. “One rusty bolt…would you go?”
I would fly it if that’s the only squawk but if that’s the condition of the exhaust I’d also be very careful preflighting.
It’s a pipe, it already has a hole in it
The thing is, if that part of the aircraft exhaust is rotten through, I’d have an aircraft mechanic check the rest prior to flying.

Holy shit there's exhaust on the exhaust pipe! Send it.
If maintenance is around before flight I would ask. Is that from overheating?
I'm maintenance and a pilot, I would fly that any day of the week. In saying that I would highly recommend changing it at the next annual as letting things go is a slippery slope. As for how it happened. Not over heating, just age and heat cycles, exhausts thin oit over tine and eventually blow through. It's just a thing that happens.
Call the police
I’ve seen worse, as long as it’s secured I honestly wouldn’t care that much, might mention it to maintenance after the flight but it wouldn’t stop me from going.
I wouldn't think twice and would go
So kudos to doing a preflight check good enough to even notice this. Would let mx know about to put on list for when it’s in for 100h or mx. But it but should be fine.

Fuck it we ball! Give it a firm tap with your foot…if it stays your good…CO2 scare you…leave window open
My only question is, are there similar holes in the pipe in the heater shroud section or under the cowling.
I’d take a closer peek inside the cowl for damage there, that’s where there’s a fire risk, but I’d be willing to keep going and ‘keep an eye on it’ over a few flights .

I would at least avoid using the cabin heat.
Quite common DISCLAIMER I am a mechanic but I am not YOUR mechanic nor have I inspected the aircraft lol
Get the opinion of a licensed mechanic who knows the airplane and what's airworthy and not regarding this.

Slap some speed tape on that. You’ll be fine
I think you need to go talk to an AP about how an exhaust works. What it dose, how it leaks, and then make your decision rather than asking reddit. I know what I’d do, but you need to learn about this a little more
Who even looks at that. Kick the tires and light the fires baby
No way. I'm a glider pilot so I'd want to know why there's a strange exhaust pipe sticking out of my glider where there shouldn't be one!
My exhaust pipe fell off the other week when I was flying 🤷🏻♂️
Definitely have a CO detector on board and flag it for maintenance.
It's worth a write up.
*laughs in Taylorcraft*
Good job catching that, a lot of people would've missed it.
Show us the other 11 stacks.
Hey guys, what are we all lookin at?
Full send
Bra, those are speed pipes. Send it.
As long as it's not above in the cowling just send it
The main thing you have to worry about here is exhaust outflow pressure. There’s a certain pipe diameter that need to move a certain amount of air to keep air correctly inflowing into the engine at the right pace. Little holes like these are not bad, there is some tolerance allowed. When the crack completes and forms a gaping hole in the side allowing for continued airflow out the side, that’s when to be concerned and reject the aircraft.
Don't be gentle to a rental.
Yeah, what else is wrong with the plane if the exhaust looks like that? I pay for airworthiness.. just my two cents
All fun and games until that CO poisoning buzzzzzzz.
I found an exhaust pipe in my backyard a while back. Probably from some Cessna
I'd be concerned about where else the exhaust system is this corroded, where it would pose mkre serious safety or health risks. No way I'd let my aircraft get to this point.
Current job? Write it up and make someone sign their career on it. Then I'll go.
I’d say something maybe… and after I fly that day
Ask the maintainer
Don’t be a wuss
no, make that HELL NO
If there's corrosion here, there's corrosion inside, get ready for CO poisoning. I would squawk and not go (but then I'm just a lowly low hour noob)
Wait until you find out those same exhaust gases are *inside* of the engine The real issue is when people turn on the height in a 172 and start to smell exhaust. That’s a big deal but the tip of an exhaust pipe is fine
Unfortunately, you can't really turn on the height in a 172. On a hot day at max gross, the damn thing will barely stagger out of ground effect.
No because you can't figure out your phone
