[f-AA] Prop Bolts

[John Baker]

DD,

 

Typically, the installation with the tapered shaft flange will use standard
AN6 bolts with a drilled shank. Length of the bolt will depend on the
propeller used.  I believe my setup with a W72CK42 prop and Chief spinner
used AN6-55 drilled bolts.  AN310-6 castle nuts, AN960-616 flat washers and
AN380-3-3 cotter pins are standard.  I have heard, second hand, of the use
of AN365 lock nuts being approved and/or used, but do not think their use is
universally accepted. Carl White may have some additional input on this.
With a Sensenich wood prop, you will need the Sensenich A-437 bushings and a
crush plate.

Hey Clan:

What type of prop bolts are used on an A-65-8 with the tapered shaft prop
flange?  Need the AN or NAS numbers and how you safety the prop.  The last
IA allowed nyloc nuts to secure the propellor; however, my new IA and I an
not certain if this is approved.  

 

Any help would be greatly appreciated so I can get the Champ ready for the
Sparta Illinois Winter Fly-In on Dec 16.  Last year there were 2 airplanes
at the fly-in, a record.  Of course they were frozen in until Spring.

 

Thanks for the help.
