Yes. The Caravan was not the only piece of swiss cheese.
At 1343:28, the pilot of the Caravan made a broadcast on the CTAF stating that the aircraft was entering and rolling runway 06. The SFIS controller heard the Caravan pilot’s ‘entering and rolling’ broadcast and was aware of the developing conflict between the Caravan and the B737. However, the SFIS controller elected not to issue a safety alert (see section titled Safety alert).
The ‘entering and rolling’ broadcast was the first transmission the flight crew of the B737 recalled hearing from the Caravan pilot and when they first became aware of the Caravan. At 1343:36, the B737’s FO made a broadcast on the CTAF stating that the B737 was on a 5 NM final approach for runway 24. Neither the Caravan pilot nor the SFIS controller responded to this broadcast.
