Prop AD
« on: November 17, 2019, 09:23:20 AM »
Hi All,

Can anyone recommend a good Prop shop in the south (Mo,Ar,Tn,Ok, Tx etc) that are familiar with the HC82X20-1B prop and inspection for the AD?

Also, what have others been paying for this inspection?

Thanks in advance,

Thanks for the reply rmartell.
I called several places and no one would touch it until I called Memphis Propeller in Olive Branch MS. They quoted around $1750 for the inspection required by the AD. Now if it doesn't pass I'm not sure what I would do. A new prop from Hartzell cost almost as much as the airplane is worth. I guess I would look into an MT prop. I wonder what others have done...

best regards,

Hi Kevin,

Fosters were the first I called. They wouldn't touch it.
Hartzell quit publishing repair manuals etc. for the old props so I guess that gave them a reason to stop testing them. Memphis Propellers will still do the testing and they quoted the $1750 which sounded fairly reasonable.

Thank you though for taking the time to reply,

Best Regards,

Sorry, I didn't respond since the shop we use is further away. Sensenich Propeller in Gainsville, GA does the HC-B3Z20-1 props for the GO480's and are very familiar with them. I don't honestly know if they do the AD on your prop but worth a call. Ask for Dan Landis, 770-538-0444.

Link to the 2 previous posts about MT prop I think their two blade prop is fairly reasonable as far as props go.

You will probably have to do at least a one time STC since even in AK field approvals are getting hard to get. BUT MT prop people will work with you to get the approval needed.

Thank you Jim and Doug for your replies.
Jerry Foster called me back and had found an MV prop that was overhauled by another shop for 15k. I thought that was pretty professional of him. He wasn't making a dime off it but still took the time. I guess if mine doesn't pass I would probably pay the extra 5k and go with the MT.
