This has been discussed at length in numerous threads all of which are merged, but:
It's worth noting that the passenger was the foremost expert on Aerocommanders in the southern hemisphere (if not the world), and the pilot was one of the more experienced on the line at the time. At 7,000ft the aircraft is nestled right into a reasonable turbulence penetration speed at cruise settings.
With the experience onboard, a low time airframe (one of the best in the fleet) and the aircraft comfortably in its niche, you could all but rule out over manipulation.
The only freight onboard was tools and parts for repairs to another aircraft.
Anecdotally, in the past 6 years I can think of at least 5 CB penetrations by Aerocommanders, that the pilots and aircraft have come away from relatively unscathed.
