Eddy Current AD


Recommended Posts

Now I am confused!!!!!   I looked at the above listed AD very closely and could not find a reference to serial numbers not affected.  Only the A and B hub are exempt.  And the required peening refers to the blade shank as far as I can find.  Cant find anywhere peening is required on the hub.  Of course the prop shops I checked with could be wrong but i would really like to show them documentation to prove them wrong.

one more little consideration....if you have a prop strike of any sort with that nice new hefty B hub then you are hung for another hub if the blades are usable as is the case in a great number of instances.  The B hub has a flange that gives way with pressure on the shank in almost every instance of strike.  The eddy current ones had a heavier flange and in most cases are reusable.  I owned a prop shop for years so this is not just blowing smoke.  Would be glad to show you an example of each hub.

Want to buy my old hub?
