This crash (thankfully no body bags, nice job on the evac) seems to hinge upon three core elements:
1. Decision to go around (SOP based or condition based?) - possible "supervisory error" finding
2. Go around actions taken (pitch and power?) - possible "training/CRM" finding
3. Decision to raise gear (when?) - possible "training/CRM" finding.
Some comments regarding corporate culture and their influence (sometimes insidious) have been made here, but whether or not the final report addresses that remains to be seen.
Someone pointed out earlier that had the plane settled with the mains still down, there may still have been some damage to the aircraft (due to a firmer landing/thump) but significantly less damage than with the landing gear up and the aircraft sliding down the pavement. (For example, less likely that engine integrity / mount being compromised ... fire ... )
