1950 So Cal Nevada B-25 Accident The 1950 So Cal Nevada Interstate accident occurred when an ex-USAF B-25 crashed while on approach to the So Cal Airport following an engine failure. All 6 crew members were killed. The aircraft was completing its last test flight before joining Air Metro - Nevada. - Details : The aircraft, a North American B-25 Mitchell, departed the So Cal Nevada Interstate Airport for a local test flight around the area. The aircraft was operated by the United States Air Force during the second world war, and it upgraded to a civilian plane. It was one of the many B-25s that were purchased by Air Metro. The crew consisted of two pilots, the Captain, who had over 10.000 flight hours, and the First Officer, who was also experienced, with over 6000 flight hours. Also included were the navigator, whose seat was located in the nose section, the flight engineer, who had 2000 flight hours, and was preparing to be First Officer with Air Metro after this flight. There were also two Air Metro aircraft engineers, seated in the tail section. The aircraft departed with no problems, the crew completed the entire test flight in one hour. The Captain decided to conduct a high altitude circling approach which the other crew members agreed to. (Computer generated photo shows the high speed circling approach that the Captain decided to conduct) - Approach : The aircraft was cleared to approach by the ATC, weather conditions were perfect at the time (calm wind, sunny day...etc), and everything seemed perfect for the Captain. Suddenly, while flying over the sunken highway, the aircraft a dual engine failure, the Captain sent the following transmission: "NA B-25 we have an engine failure, we're goin around". The aircraft was observed making a very high pitching go around, with the wings rocking side to side, before it entered a descending right bank. (The descending right bank) The crew were unable to pull out of the descending dive, and the plane impacted terrain just a few meters from the runway end, near the intersection leading to the highway. The aircraft was completely destroyed and all 6 occupants were fatally injured. (Impact) Site : 0.1 km S of So Cal Nevada Interstate Airport, NV, USA Summary : Engine failure, pilot error during the subsequent go-around Aircraft Type : North American B-25 Mitchell Operator : Air Metro on behalf of USAF Registration : N99439X Crew : 4 Passengers : 2 Survivors : 0 (1 Initially) Fatalities : 6 (all) Injures : -- Phase : Approach Nature : Test Departure Airport : So Cal Nevada Interstate Airport, NV, USA Destination Airport : So Cal Nevada Interstate Airport, NV, USA Damage : Destroyed - Cause : The Civil Aviation Safety Board determines that the probable cause of the accident as the following: The Captain failure to maintain speed and control while conducting a low speed go-around following a dual engine failure. The dual engine failure happened when the radial engine's crankshafts stopped due to metal fatigue. Contributing factors: The Captain failure to retract the landing gears during the attempted go-around, which resulted in higher drag forces to the aircraft. The First Officer failure to assist his Captain during the emergency situation. The crew's agreement to conduct the high altitude approach. The failure of multiple aircraft engineers to inspect the engines crankshafts.
