Analysis
The flight was inbound to FAT following an operational exercise with two ANG F-16s. Northeast of the airport, about 9,000 feet MSL, VFR, the flight called approach control, declared an emergency due to engine fire and requested immediate vectors to the airport. Approach control asked the flight which runway they requested and the flight replied 29. The flight was seen on radar at 6, and then 4 nautical miles at 4,000 feet MSL, with the airport at 12 O'clock. The flight reported field in sight and was handed over to the tower. Intracockpit conversations were transmitted on tower frequency until impact. A pilot mentioned possibly having to make a 270 degree turn, but the flight was seen passing through the extended centerline of runway 29, about 1 1/2 miles from the approach end of the runway, appearing to be low and fast.
The airplane impacted to the west on Olive Avenue. Witnesses reported that the airplane impacted in a nose low and left wing down attitude. The airplane immediately became a fireball which slid down the avenue. Several apartments on the north side of the avenue became ignited. Some major airplane components, including the right wing, right engine, and empennage came to rest on the avenue. The left engine came to rest in an apartment unit. Both pilots were fatally injured. There were injuries to persons on the ground.
