I have read and also heard second hand that the government has been pulling them off of the Husky's and is going back to Harzell because of the increase in maintenance costs. Not sure if it is pilot issues or other. Wondering if anyone has the low-down on that or if it's just hearsay.
There have been several instances (again second hand info) of de - lamination as well as the metal leading edge leaving the blades.
It's winter in Alaska and the rumors abound, hopefully someone can get the facts.
Just talked to one of those "government pilots" yesterday about the MT prop on the Husky he's flying. He loves it, and isn't giving it up. Neither is anyone else.
There have NOT been any cases of "delamination" in these props that I know of. There have been some cases of VERY tiny cracks that got folks wound up. All these were repaired at no cost to the owner, other than shipping one way. And, frankly, every one of those I saw were cosmetic in nature. The company has been really good with customer service.
I know of ONE case of an MT prop that leaked oil, and had to be repaired. That too was done under warranty.
I do not know of any cases of the SS leading edge strip coming off an MT prop, though it certainly could happen, I suppose.
Give Flight Resource a call and talk to them about these issues. Those guys are good guys and they'll tell you honestly about any issues they've seen with the props.
Now, try dealing with Hartzell. All they do is issue an AD on your hub, and let you deal with it. At your cost.
