A quick reading seems to me to indicate a very sloppy approach with a first officer at the controls who was behind the aircraft and getting a cockpit GCA from the captain.
Not much in the way of an approach briefing, confusion about distance to the field, maybe forgot to arm the approach. Flaps 20 were set, don't think they did a landing checklist. Never got flaps 40, slowed to v-ref, stalled turning to final on the ILS 6 circle to land runway 1.
The FO gave the controls to the captain and a stall was called less than fifteen seconds later.

The docket opening marks a transition in the investigative process where the majority of facts needed for the investigation have been gathered and the NTSB can move ahead with analysis of those facts.
