I understand this cable tie is not holding the prop, but why is it the exactly?

KopfSmertZz@reddit
It is just holding the goo to the prop, no worries
RemarkableFig2719@reddit
Very Indonesia
BrownLightningBro@reddit
There are around 36 cable ties on ATR props, that one there just helps keep the de-ice wiring from chafing
Boundish91@reddit
Why cable ties? Bad design?
BrownLightningBro@reddit
Great design. Easy to remove, easy to install, and probably relatively cheap as far as aircraft parts go. They are not load bearing, purely to prevent movement that would lead to chafing.
UltraViolentNdYAG@reddit
And at 1,800 RPM (or whatever), centrifugal forces are not induced making it "load bearing"?
Felipe_Sexo@reddit
They are simple and they do the job
_esci@reddit
und what about that huge lump of glue or corrosion? is that also also standard procedure?
BrownLightningBro@reddit
PRC, common aircraft sealant. They've made a mess of it, but im sure it will do the job until it gets to a maintenance base for a more permanent repair/blade replacement.
Fantastic_Shake_9492@reddit
While it’s hard to mess that up, the lack of precision in this makes me wonder what major repairs were done improperly by this tech. This station should probably be audited sooner rather than later
robtk12@reddit
Ha ha, Blade replacement.

Buddy you gotta speak with conviction on something like this. "I'm sure" ain't cutting it lol
BrownLightningBro@reddit
Hard to speak with more conviction than that, without inspecting it in person.

It’s Lion Air - probably the worst of the budget carriers in SE Asia and one of the very few airlines I will just refuse to fly.
GirlScoutSniper@reddit
I've watched enough Mayday Air Disaster shows to know this name.
BallisticHabit@reddit
Same.
I knew I recognized the name.
TomChai@reddit
That lump probably throws off blade balance but should be within limits, it's supposed to be a temp fix until the plane gets back to home base and have the prop blade replaced.
fried_clams@reddit
Are they usually white, like this one? I didn't think white cable ties were UV stable.
BrownLightningBro@reddit
Normally black from what I've seen there, but again, probably just a temp fix to get it home.
grimrapper2001@reddit
Most of the cable ties used externally are the black “UV resistant” type. Exception being on propellers and landing gear.
Danamaganza2@reddit
Surely a p-clip would be necessary here?
BrownLightningBro@reddit
No. There are 1500+ ATRs that have come off the production line, and they are all full of zip-ties, nose to tail. They are not load bearing, simply to prevent chafing.
ExtensionList8801@reddit
Why would a foreskin clamp be needed?
SuperFriendlyAv8or@reddit
Question: are these ordinary zip ties like you might use at home, or are they super-duper aviation specific zip ties? I would have assumed that the forces of the prop (and general vibrations on an ATR) would destroy them pretty quick...
ElectricalChaos@reddit
Ordinary run of the mill cable tie. The thing about vibration is that stuff needs to be loose for damage to start occurring. If things are tight, nothing happens.
Original_Morning_649@reddit (OP)
Good to know, thank you.
SweatySwim3411@reddit
When i went parachuting the plane we went on had duct tape on the wing. Made things a little more stressful for me.
Original_Morning_649@reddit (OP)
At least you had a parachute.
SweatySwim3411@reddit
Until the cord was pulled i was skeptical.
LearningT0Fly@reddit
Speed tape*. It’s designed for repairs on aircraft.
secretpenguin0@reddit
All jokes aside, a properly sized plastic band will hold just fine.
Not the prop of course 😂
claws76@reddit
Duude I first thought it was a squirrel, then a dead squirrel zip tied…
analphylaxis@reddit
You are not alone.
VoiceActorForHire@reddit
my exact thoughts, i was thinking what purpose does a dead squirrel serve when zip tied to a prop
MooseBoys@reddit
for good luck

Probably just a single blade out of balance. Better than adding a lead weight and more "eco-friendly".

Came here to say this!
EvenMoreCoconuts@reddit
What is that really though?
Dizzy-Tennis-5518@reddit
Thought it was a wasp nest
Majestic_Magician243@reddit
It's securing the connection / wires for the heated deicing boot on the prop blade. Normal.
streetlegalb17@reddit
It keeps the prop stimulated
Phil9151@reddit
I always stimulate my prop state.
patrick24601@reddit
Stimulated ? Or does it keep the oil from flowing out of the prop back into the engine ?
Garmberos@reddit

Puzzleheaded-Emu6338@reddit
I think it’s for the prop anti-ice system

Possible repair to the boot? But just hope its balanced.

EvenBear1118@reddit

Skasue@reddit
Do pilots get notified, and personally inspect repair jobs?
Because I’d trust the guy willing to fly with a repair job, then a mechanic thats just given the “all good trust me bro”.
Wikadood@reddit
Pilots only do a walk around to make sure theres no obvious damage. Mechanics are the ones doing detailed inspections and that trust me bro it signed in blood technically because of how big a sign off is to do since its confirming the aircraft is airworthy and anything wrong will come back to you.
putlermustdiehorribl@reddit
Don't worry. They have a spare plane. Just in case.
Jeff61059@reddit
It’s holding the crack in the prop together while the Liquid Metal cures. Can a FAA mechanic confirm this?
usernamechexoit@reddit
ATRs are simultaneously the most amazing and absolute worst aircraft around. The repairs look like sh1t, everything is rotten and yet these things keep flying with a decent safety record. You should see what some of the landing gears look like when they come in for overhaul.
Felipe_Sexo@reddit
They are common, I've worked on Airbus c295 and they have them too. Also the plastic covers between the blade and the cone are connected by velcro and small zip ties
Extension-Brother291@reddit
Looks like poop to me am I wrong
Flyby-1000@reddit
It flew in that way, it'll fly out that way!!!
30K100M@reddit
The logo is probably more unsafe than the ziptie.
Past_Difficulty_7706@reddit
Relax there is some JB Weld on there too
star744jets@reddit
Prop de-icing boot delamination. It seems legally repaired as per Minimum Equipment List probably with a maximum time to repair and strict limitations such as ´Do not operate under icing condition ´.
rocketwilco@reddit
i am shocked to learn props need de icing.
i figured centrifical force was very powerful
kss1089@reddit
If you look again, you will notice the de ice boot only goes so high on the blade. that is because ice can and does form on the blades. The reason why the boot stops instead of going all the way to the tip is that ice can only "hang on" until about 600 G's of acceleration.
Smaller piston props that spin at 2,700 RPM will have shorter boots than large turbo props that spin at 1,700 or 1,591 RPM.
I have replaced boots on aircraft without fully disassembling them by doing a static and dynamic balance on the prop. HOWEVER, this was only during engineering test flights on non certified aircraft and or propellers. I am not suggesting or recommending that anyone ever do that. It sucked. much much easier to put a boot when it's out of the prop on a bench.
Source, I am a propeller engineer.
railker@reddit
Sure does, though I can't say I've ever seen it as it's usually gone, the evidence is in the ice shields installed to mitigate the damage from the ice shedding off the blades. Those things get absolutely battered in winter.
josiasroig@reddit
VoePass agreed with that
Ch0singRnN@reddit
Not a thing you would like to hear on an ATR
ForgotPassword_Again@reddit
You’d be surprised how much plastic holds airplanes together.
Macallan18Year@reddit
That is just a really shitty prop deicing system wire routing job on that blade. She ain't goin' to the moon, it'll be fine.
Wise-Boysenberry5286@reddit
Used to secure Prop Deice wires on alot of planes
Difficult_Question62@reddit
Definitely not safe. Protocol says to wrap twice with duct tape prior to the cable tie. Then you’re all good
Whowhatthinkisiam@reddit
What is that? JB weld?
MattheiusFrink@reddit
it's a shame my IA is no good for the 121 operators, otherwise I would ground that piece of shit right now.
Boomhauer440@reddit
Lol wow you're such a hero. Other countries don't give a shit about your IA.
MotoJoker@reddit
You wouldn’t last at an airline then lmao
Disastrous-Wall-6943@reddit
It's not a shame because that's airworthy.
It's a little ugly, but it's airworthy.
Ok_Strength9287@reddit
Nope that’s a “Military Grade” zip tie buddy
Volt_OwO@reddit
I'm more curious about the grey sludge looking thing above the zip tie, what is that?
Disastrous-Wall-6943@reddit
Sealant.
sagewynn@reddit
Thays the worst sealant job I've ever seen, and I've done alot of sealant jobs
getouttathatpie@reddit
That is what a perfect PRC job looks like after one flight when the AC dispatches before its dry
Boomhauer440@reddit
My company started using AC240 instead of PR1422 for exactly this reason. The full cure time for AC240B1/2 is like 4 hours and b-2 is 10-12. Plus you can get it in little 2oz cans that are perfect for small repairs like that without wasting a semkit or having to weigh it out.
sagewynn@reddit
Word? Looks like my poop after gas station burritos, a protein shake and 3 large mugs of coffee

GusBode@reddit

Glittering_Youth_976@reddit
That sealant job should NOT have been signed off. Sealant isn’t supposed to have an effect of prop balance.
davespark@reddit
I thought dead bird, cause you know, it’s a plane
klahnwi@reddit
Should never use those zip ties to hold the prop onto the plane. Instead, should use black zip ties. They handle deterioration from the sun better.
XsancoX@reddit
There better be a free seat in a different row. Not gonna trust this Final Destination cable tie situation.
Wumbologists@reddit
Pov: when non-mechanics think they are mechanics
StorminXX@reddit
That does not look very proper.
Uh_yeah-@reddit
Oh, it’s props alright
Crusader1865@reddit
This is a great example of a structural zip tie.
jad1223@reddit
The cable? I don’t know. Flying Lion Air? Not super safe
Anarolf@reddit
Ty wrap is there to secure leads to the deice heater mat/boot that's on the leading edge of the prop blade. It's usually lacing cord and a terminal block not visible above the spinner. The mud looks like sloppily applied aircraft sealant (PRC), there may have been some arcing from the boot, or some physical impact on the blade hub. Doubt any of those are found in the blade CMM. Now you are allowed to disable the deice and restrict the aircraft from known or forecast icing conditions for a short while
getouttathatpie@reddit
I wonder if they did a gate repair and launched before the edge seal was dry
NorthEndD@reddit
It will be dry and windy pretty soon.

no seriously, Lion air, it’s crap everything from bottom to the top.
Original_Morning_649@reddit (OP)
Yeah I’m well aware of their reputation. Although, on certain routes it’s the only carrier here in Indonesia.
SnooSongs8218@reddit
...and their fast, their aircraft made it to the crash site a whole day ahead of the aircraft crash investigation team... 🫣
747ER@reddit
This should have way more upvotes. LionAir is an extremely dangerous airline. This is their regional subsidiary, Wings Air, whose actual, official slogan is literally “Fly is Cheap”. They do not care about safety, and if it weren’t for their bribery and connections to the government, they would’ve been shut down for safety reasons long ago like AdamAir.
Dumyat367250@reddit
Why the down-votes? You are on the money. Unlike that airline.
pocpocpocky@reddit
maybe some Lion air fans….. i am just telling the truth like it is dudes.
Thick_Sympathy_8021@reddit
That's a cable tie giving a garden orb weaver spider a safe home while she is safely transported from wherever this originated to wherever ot ended at the speed of yeet. Safe travels... her brain is mush... yeet confirmed... I'm sad now.

wdatkinson@reddit
The cable tie is holding things together while the bondo dries.
Kaiisim@reddit
Probably safer than a cleaner looking equivalent.
Much like speed tape, they are the using cable ties from amazon, they should have very high tensile strength ones.
You can even get stainless steel version with upto 1000lbs of tensile strength!

That’s probably tightening a faulty seal as a temporary solution. There is a lot of grease on the prop.
