As per your suggestions, have realigned the PAPI. The PAPI height is 630.6 feet and 3 feet below the RWY at TDZ. The threshold is 1166 feet to the north.
The graphic at
Post #554 has been changed. A larger scale graphic is

I think the NTSB reference to 140 KTS IAS was probably taken prior to the initial contact, and time-wise the distance from impact to the top of the hill to the north of Bethel Dr equates to 9 secs and 130kts. I suggest that the tree felling had an impact on the final speed.
