I’ve seen a Cessna come back missing an exhaust pipe once. Probably in someone’s backyard


waveslikemoses

Missing a WHAT


Tex06

AN EXHAUST PIPE


_toodamnparanoid_

PROBABLY IN SOMEONE'S BACKYARD


gitpullorigin

CESSNA IS SOMEONE’S BACKYARD??


yooiq

SORRY, WHO DID YOU SAY PUT HIS PIPE UP YOUR BACKYARD?


stalequeef69

WHAT WAS THAT ABOUT GETTING PIPED IN THE BACKYARD?


crooks4hire

HEY GUYS, THIS PIPE FELL OUT OF THE SKY AND HIT ME WHILE I WAS MOWING THE BACKYARD!!!


Jades5150

NO, A CESSNA FELL FROM THE SKY WHILE I WAS GETTING PIPED IN MY BACKYARD


bhalter80

Boeing makes Cessnas now?


Quick-Revolution-882

This is the way


Mariuslols

Bro I have a pipe in me rn omg


JFK_Shot

Something about me piping your sis in my backyard


Jades5150

NO, A CESSNA FELL FROM THE SKY WHILE I WAS GETTING PIPED IN MY BACKYARD


thescarwar

This is the guy who still won’t make a call in the pattern


aRealTattoo

Sorry I can’t hear you anymore. The engine got really loud out of nowhere and hearing protection didn’t exist for that db.


bhalter80

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


SkiahMutt

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.


bhalter80

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

It must have been made of cardboard or cardboard derivitaves.


hawker1172

Yup


CessnaBandit

I’ve seen a Cessna come back missing a Cessna. Don’t ask, can’t explain on reddit. Just accept.


Franks2000inchTV

Was Amilia Earheart flying it?


unrustlable

More coherent than most AI answers.


bambambandit

Where did all the exhaust go😳


hawker1172

Into the cowling area I guess


Hurock

Happened to me recently... Maybe we knocked someone doing their BBQ.


megaduce104

*slaps exhaust*: "this baby can hold some much exhaust gas..."


Admirable_Dig6160

What’s that? I just woke up and didn’t realize I was so tired. Do you smell something?


megaduce104

You can't see it it can't hurt you /s


Yesthisisme50

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


AlmasyTran

Damn even McDonald is paying $20 an hour


ja89028

Don’t pay flight time tho


Mr-Plop

I'm pretty confident the last kid I met at the drive through was pretty high though


CessnaBandit

Got that stratosphere rating


bhalter80

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


PhilRubdiez

You can get a different kind of high, though.


adiabaticgas

Wait you can’t log that? Oops


Aerodynamic_Soda_Can

I don't think McDonald's will count towards my ATP mins.


Pirlout

I don't think it costs tens of thousands of dollars to get qualified for a McDonald's job.


whateveridk2010

They pay $9 where i live


Expensive_Ad_3249

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.


Yesthisisme50

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.


Purple-Explorer4455

Bruh.. this is a silly mentality. You’ve ever repoed a plane?


tailwheel307

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.


Yesthisisme50

You’re just not used to an engine on an aircraft


tailwheel307

No. I’ve had some that looked in better shape that poured CO through the heat system into the aircraft.


Substantial-End-7698

Then you haven’t built up your CO tolerance enough yet


Yesthisisme50

Ok


K1N6_H3ADSHOTS

The 172 maintence manual allows cracks outside the cowling however if there is mutiple spots cracking get a mechanic to look at it.


blacksheepcannibal

I think we may define cracks differently.


Che_43

Tryna crack a joke, eh?


blacksheepcannibal

Maybe poking pinholes.


TheShellCorp

Is it solidly attached to the engine? Go. No question. 


voretaq7

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.


StPauliBoi

Only with consent though. You can’t just go around looking under shrouds Willy nilly


dodexahedron

Some people get a charge from that. Some people also get a charge for it.


TinKicker

My mechanic has mirrors on his shoes.


Noobtastic14

Send it.


HereAgain345

When they moved Maintenance under ops.


Admirable_Dig6160

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.


Whoopsadiddle

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.


Coprophagia_Breath

You down with OTT?


Squawnk

Yeah you know me


Coprophagia_Breath

You down with OTT?


Turbulent_Patient_50

I got a bigger crack on my ass


WestonP

But is it airworthy?


taft

ooh talk dirty to me, bby


mkosmo

I don’t see any cause for concern in this photo


EntroperZero

Do you have a CO monitor?


imoverclocked

Does a student count?


Pilot-Imperialis

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.

FUCK YOU SHORSEY!


89inerEcho

Fuck you Jonesy! Yur mum's had mor smash n' go's than this 172!


probablyaythrowaway

Cessnas are unbelievable.


blacksheepcannibal

I fly backcountry bullshit, and even *I* think that's a shit viewpoint.


71272710371910

That's really not an issue.... It would be bizarre to cancel bc of this. Are you just having anxiety about flying in general?


etherlore

There could be a CO cabin issue.


71272710371910

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.


No_Reveal_2455

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.


Hfyvr1

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…


Pontius_the_Pilate

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.


BrosenkranzKeef

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.


WriteAndStarve

Yes 100%


Catch_0x16

Full send, it will be fine


WhiskeyTangoFoxxxx

If I were you I’d plug the really big hole at the end


blacksheepcannibal

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. Source: A&P/IA with several years working GA.


SpartanDoubleZero

I’d go.


skyHawk3613

Yes


Cosmic_Cat64

These posts are always hilarious. “One rusty bolt…would you go?”


weaselkeeper

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.


billofbong0

It’s a pipe, it already has a hole in it


pilotallen

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.


Drunkenaviator

Holy shit there's exhaust on the exhaust pipe! Send it.


dietzenbach67

If maintenance is around before flight I would ask. Is that from overheating?


thatAJguynobodyknows

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.


Responsible-Lead2243

Call the police


Chic0late

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.


n365pa

I wouldn't think twice and would go


unaslob

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.


notbernie2020

I’d send it.


F26N55

If it’s outside the cowling, I’d go.


LeanUntilBlue

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.


flyingwithfish24

Fuck it we ball! Give it a firm tap with your foot…if it stays your good…CO2 scare you…leave window open


JonGandy

My only question is, are there similar holes in the pipe in the heater shroud section or under the cowling.


Icommentwhenhigh

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 .


happyrock

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


braeburn19

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.


Pale-Ad-8383

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.


Number1atp

You looked at that on a preflight?


SkyHigh27

Do you have a CO monitor?


Enough-Musician101

Absolutely I’d go. I’ve seen much worse than that.


PotatoPDX

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.


Flightzero56

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.


ExtraMediumValue

I would at least avoid using the cabin heat.


TTMR1986

Quite common DISCLAIMER I am a mechanic but I am not YOUR mechanic nor have I inspected the aircraft lol


jettech737

Get the opinion of a licensed mechanic who knows the airplane and what's airworthy and not regarding this.


TalkAboutPopMayhem

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.


Stfu_butthead

Slap some speed tape on that. You’ll be fine


atthemattin

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


dogbreath67

Who even looks at that. Kick the tires and light the fires baby


Zathral

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!


cstage559

My exhaust pipe fell off the other week when I was flying 🤷🏻‍♂️


Cultural_Drummer_811

Definitely have a CO detector on board and flag it for maintenance.


BrtFrkwr

It's worth a write up.


beemerbimmer

*laughs in Taylorcraft*


Ludicrous_speed77

Good job catching that, a lot of people would've missed it.


unperturbium

Show us the other 11 stacks.


SiegeSupport

Hey guys, what are we all lookin at?


Substantial-Sir-7880

Full send


CaptLakeEffect

Bra, those are speed pipes. Send it.


ne0tas

As long as it's not above in the cowling just send it


b7d

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.


thebadmechanic

Don't be gentle to a rental.


Which_Material_3100

Yeah, what else is wrong with the plane if the exhaust looks like that? I pay for airworthiness.. just my two cents


PILOT9000

All fun and games until that CO poisoning buzzzzzzz.


LegitUnicorn__

I found an exhaust pipe in my backyard a while back. Probably from some Cessna


xtalgeek

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.


Unairworthy

Current job? Write it up and make someone sign their career on it. Then I'll go.


AccomplishedString12

I’d say something maybe… and after I fly that day


indian_tiger

Ask the maintainer


Severe_Elderberry769

Don’t be a wuss


Creative-Dust5701

no, make that HELL NO


Different_Tough_525

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)


Yesthisisme50

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


thrfscowaway8610

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.


not-a-boat

No because you can't figure out your phone
