Default Prop separation. Who's at fault?

I had a brand new 16-8 3-blade prop on a new g-38 and a new hanger 9 cessna. The prop broke on the first flight, twisted the crank, broke the engine mount box and a hole in the side of the plane where the broke piece hit. Should the prop manufacturer be liable?

Should they be?

Maybe.

Will they be?

No.

Who is to say that it wasn't on the ground at the time, and got hit with a dropped chicken stick? Or maybe you flew into a bird, or some small, unseen item?

It's sad, but I doubt you would have a case.

Looking on the good side NO One Was Hurt and thats a good thing.

I don't think you could make a good case in a court room, Did UPS drop the package? did the kid at the hobby store drop it on the floor?could an unballanced engine cause it to come apart? Did you balance it before use? did you over Toqure the prop not causing this prop damage/failer?

As you can see the possable what if's are endless, and most Judges "sence no one was harmed" would throw it out.

You might ever so nicely plead you case to the prop company and see if you get any compensation some Co might help you out if thay feel it will help them. (you never know untill you ask)

Tough one to prove. Did you hit a rock on the runway? Lots of factors. Bummer!

Sorry for the loss.

There's so many opportunities for user error, that I don't see the prop manufacturer as being likely to volunteer to take the blame.

In addition to the above valid questions about whether the prop hit anything, or you over-tightened the nut ...

Did you use a spinner ? If so, did the cutouts in the spinner touch the blades of the prop ? Can you prove that they did not ? (including proving that the spinner did not rotate during the flight due to prop not not being tight enough).

I'm not claiming that you did the above - just pointing out how the prop manufacturer can look at it.

ok, sorry if i'm missing something here but am i right in thinking you put a 16-8 3 bladed prop on a size .38 cu engine?

i think i might have got this wrong here but if that is the case, i'm not really surprised that it all busted up and broke the engine

A 16-8 3-blade should be right for a g-38. I'm not looking for a court case. Just a little upset because everything was new. I'm just going to suck it up and let it ride. I have already ordered all my replacement parts and i need to send the engine off.

Did the same thing you did, typing while you were hitting enter. You have it all figured out now.

zerodown,

Why do you think the prop broke first? Is it possible the engine was defective and turned loose first? You might take a stab at a warranty claim on the engine (since you said it was new).

Like above I wound bet your engine let go first (thus bending the crank) and then threw the prop.

Ever seen a gas motor backfire? Goodbye prop.
