Okay. You can see why we were cautious though, right?
I get it!
The Columbia CV-107IIs with N numbers are KV's and BV's with major upgrades and service life improvements.
They have owned the type certificate since 2006.
Not sure how someone other than Columbia will make the CH/BV to N number happen.
Probably when the paperwork equals the gross weight of the -46.
I've been researching mast retaining nut installation, maintenance, pre-flight inspection, and incidents since theis occured.
I never expected or have every heard of a total separation of rotor and drive system together.
This is why you let the investigation team do their job, and minimize speculation.
Was always taught that mast bumping would cause failure to the mast, not total drive system separation.
But, I've never been on an investigation of a mast bump incident, so can't say for certain.
This incident with a 206 was mast bumping and the mast failed.
NTSB: Ergonomics Explain Main Rotor Loss During Flight Test - Aerossurance
Ergonomics during a flight test was likely cause of a mast bumping event say NTSB. The dual controls remained fitted and a flight test engineer was holding a 3.5 kg laptop over the cyclic with one hand while making notes with the other.

More than one Marine General received this appropriate salute from the flight line as they taxied out to get some flight time in our squadron's aircraft. Oh such wonderful memories.

It's a sign of the troops affection sir!
I saw a video by an aeronautical engineer who believes the cause was likely a catastrophic MRGB failure (actually locking up rather than breaking apart internally) and the sudden rotor stoppage actually ripped the mounting deck cleanly away from the fuselage. He believes the evidence will be found in the tension on the MRGB mounting struts that did not give way. He also notched that the tail separation was too close to the body to entertain mast bumping. If this is accurate that surely must be a very rare event.
Interesting and plausible explanation! Scary as f*ck.
