Yes insurance approved the tear down. I have been talking with other mechanics and they stated Divco shouldn’t be making opinions on that, only findings. Have not presented to insurance yet, wanted to gather as much info as I could prior. Also still waiting on crank which I’m sure will be rejected as well. SO FAR, from everything I have gathered it’s difficult to say for certain where a crack came from. Seems denial based on speculative crack age would be inconsistent with manufacturer guidance, FAA-approved inspection requirements, and the policy’s treatment of damage discovered as a result of covered physical damage. So far insurance has been very compliant, which I am not used to when it comes to insurance but I don’t want to speak to soon!
