The Ford 5-AT-C Tri-Motor was destroyed by fire after it impacted the ground near Oceanside, California in poor weather conditions. The aircraft had departed Agua Caliente, Mexico at 17:30 hours. The flight ran into blinding rain from a sudden squall that had blown in from the Pacific. The aircraft suddenly lost altitude and the left wing tip touched the ground, throwing the plane on its nose.

The T.A.T.-Maddux technical board of inquiry stated that the accident was the result of "a local weather condition of unpredicted and unforeseen characteristics."
