So I guess we have to look elsewhere to see whether the CH-7, or the CH-77 for that matter, is a safe kit helicopter.
As with most machinery H and H, they are as safe as their human intervention.
Yes, the machine in the closed report was abused, and suffered as any other machine would.
I know of a CH-7 with 1500 odd hours or working airtime, ( not a weekender) with few issues.
Dilligent maintainance and balance goes along way toward longevity.
I know of two others in excess of 300 hours in the same boat.
Integrity of the machine is not an issue.
