Prop Spacer?

[NW_Pilot]

Take a look at these photos let me know what you Think?

Note: only 43 hours on bird found during cowling removal when diagnosing a CHT probe failure.

MT Prop On SMA diesel.

No sign of Grinding on the cowling or surrounding area?

Safety wire appears backward on one nut on the first picture on the hub extention at the flange. Look at the right side of the picture, middle nut.

Presumably you're asking about the rubbing marks, but you write:

No sign of Grinding on the cowling or surrounding area?

If you're asking if the prop extention is rubbing on any surrounding material, if you don't know, we don't know. We're not there. You don't appear to be sure either.

What exactly is it that you're asking?

The Gouges in the prop hub are deep!\

Interesting that they say "Damage" is not a problem?


From SMA,


I confirm that this damage is probably due to a contact with the lower cowling (there should be a mark on the cowling). The cowlings have a tendency to drift upwards during flight and come into contact with the propeller hub because of soft shock mounts. We are currently certifying new shock mounts that will be less flexible and less sensitive to aerodynamic efforts submitted to the cowlings. As specified by MTPropeller, the damage is not a problem.

Wondering if it's Normal I have never seen this so called rubbing on the prop hub/spacer SMA is saying the Damage is Normal. The Little cricket in my head says it's not. They have already showed a lack of attention to detail the Pitot Heat is Labeled Pilot Heat.

The Cowling is chafing and streaking (Smoking) on the airframe...

It's a wonder that your lack of knowledge about the airplanes you fly hasn't got you killed yet.

Well, there is an 8620 hanging on the plane as of yesterday! FAA says Once through the Shot Penning it is not airworthy. They found no signs of rubbing around the area near the hub.

Another Couple Photos of Prop Hub,

Belt Hidden Behind Baffling Hard To See.

8620, Grounded! Not Only By My Word the Faa

The residue on the cowling and fuselage is nothing, its meerely aluminum oxide, or it could be from the new baffle seals, I can't really tell for sure.
The residue from the alternator belt is not extraordinary, it could just be the alignement between the two pulleys is not exact.

Without looking at a Hartzell maintenance manual, that chafing on the hub could be repairable and returned to service. The FAA sometimes does not know what is actually legal or not. I had an FAA inspector ground a C-172RG that was there for a CFI check ride because the exhaust was loose. I had to copy the parts book showing the springs on the attach to prove that it was OK.

That was one big mistake, letting the FEDS look at it without an incident occuring. Now you are screwed royally! You're on your own now hoss. You've taken a controlled situation and handed it over, congratualtions.

I am not screwed! Clients refused to do anything about this!!! That aircraft is a POS. I will not fly it across the ocean. Damage was discovered when a mechanic pulled top cowl off to diagnose CHT failure. CHT is a Required Item for STC! Clients also refused to send New CHT probe.

Screwed in as you were paid to deliver the airplane, right? Was the airplane delivered? Did you get paid for flying the airplane?
Screwed as in who called the Feds in on this? They don't usually get involved in an inop CHT gauge. Any time the Feds get involved, somebody gets screwed.
