MT prop hairline cracks

I discovered some hairline cracks in my MT prop and have sent photos to MT tech spt. Of course I hope these are cosmetic; we'll see. Have any MT users encountered this issue?

Those do not look exactly like mine, but my prop is painted black. I happen to live about 10 minutes from MT USA in Deland, FL and have flown over to have mine looked at. They assured me that it was cosmetic and was a paint issue. My prop was installed in 2008 and now has about 850 hours on it and those small cracks have been there for several years now. MT told me they started using a different paint some time ago in response to this problem. As I said, that does not look exactly like mine, but that could be a different paint. I will be interested to hear what MT tells you.
MT USA has been great to work with and are very customer service oriented, IMHO. I will probably have them overhaul mine one of these days.

Dave,
I too live near Deland (Merritt Island) and also believe these are cosmetic. Once the influence of this tropical whatever we are enduring in Florida for the next several days has past I'll zip over there and let them take a look.

I have sent these pics to Germany to the tech support guys.

Please let us know how this resolves.

Dave

MT very prompt reply





Here's the reply from MT USA (I emailed them last night and at 0830 today they replied - I'm very happy with that response time!)

"Hi Don,

Those cracks are cosmetic only, only in the paint, they do not affect the core strength of the blades. No reason for grounding the aircraft. See section 6.2.2.4 and 6.8.3 in the attached operations manual."
