Trailing Edge Breaks

[telstar]

The trailing edge on my lower right wing cracked between the 2nd and 3rd ribs. This is in the outer edge of the prop blast area.
I have been told it may have been due to prop blast turbulance.
Has anyone else had this problem ?? Is there a known cure ? I suspect it may have been initiated by improper handling, i.e. someone moved the plane by pushing/lifting on the trailing adge.
