California

En route, oil temperature got high and the oil pressure got low. Oil spread on windshield. The engine lost power and the crew attempted an emergency landing when the aircraft struck a cabin and crashed, bursting into flames. Both occupants were seriously injured.

While descending to San Bernardino Airport on a flight from Torrance, the pilot encountered poor weather conditions when the twin engine airplane hit a large boulder on a mountain ridge located in Fontana, about 9 miles southwest of San Bernardino Airport. The aircraft was destroyed and the pilot, sole on board, was killed.

En route from San Diego to Palm Springs, weather conditions deteriorated and the twin engine airplane entered a thunderstorm area with severe turbulences and strong winds. The right empennage assembly and the right outboard wing panel failed in flight, causing the airplane to enter an uncontrolled descent and to crash in flames near Palm Desert. The aircraft was destroyed and all six occupants were killed.

After takeoff from Camp Fox (Santa Catalina Island), while cruising at low height, the left engine failed. The pilot elected to make an emergency landing but unstable, the seaplane struck the water surface, lost its left float and came to rest upside down. All 10 occupants were quickly rescued while the aircraft sank and was not recovered.

Parked at Yolo County Airport, the twin engine airplane was stolen by two men who wanted to make a probable illegal flight. During the takeoff roll, the pilot lost control of the airplane that veered off runway, collided with ditches and came to rest in flames. The aircraft was destroyed and both occupants were not recovered.

While cruising at low altitude in poor weather conditions, the twin engine airplane struck a hillside near Oakland. The aircraft was destroyed and all three occupants were seriously injured.

During acceleration, the flight engineer stated, "Look at that warning light on No. 3." There was no verbal response from any other crewmember. The aircraft was accelerated normally to V1 and V2, was rotated, and was lifted off without difficulty. Shortly after the captain called for gear and flaps up, a loud noise was heard and the flight engineer announced that they had lost the No. 3 engine. The No.. 1 blade of the No. 3 propeller had and the loss of the blade caused an imbalance that caused separation, almost instantly, of the No. 3 engine from the aircraft. The propeller blade penetrated the lower fuselage of the aircraft and penetrated the lower inboard side of the No. 2 engine. As the blade passed through the fuselage, it severed pneumatic, hydraulic, and emergency airbrake lines as well as the electrical wiring for propeller controls and some engine instruments. The first officer informed the captain that the engine had separated. The aircraft continued to climb and began a right turn. An emergency was declared and the crew requested and received clearance for a landing on runway 07. Debris was discovered on the intersection of runways 07/25 and 15/23, but the pilot decided to continue the approach. The aircraft touched down near the end of runway 07. The captain called for flap retraction and for the props to be put in reverse pitch. The engine sounds increased, and the first officer advised the captain that the propellers were not going into reverse and to use the brakes. As the engine sound decreased, the captain replied that nothing was happening. Maximum power was applied and the aircraft again took off, and cleared the blast fence at the end of the runway by approximately 30 feet (9 m). At 10:39:35, the crew advised the Hollywood-Burbank Tower that they had no brakes and that they were proceeding to the Van Nuys Airport (VNY). The crew the saw that the No. 2 oil pressure was low and that there was no BMEP indication. Attempts to feather the No. 2 propeller were not successful, and the No. 2 engine stopped with the propeller blades at a positive, low pitch angle. Van Nuys cleared the flight for landing on runway 16, but the crew replied that they wouldn't make it, and requested runway 34. At 10:43:22, the Van Nuys local controller cleared the flight to land on runway 34L. While approaching the airport, the airplane was losing altitude and airspeed. The crew realized that they would not make it to the runway. The throttles were retarded and a forced landing was attempted on the Woodley Municipal Golf Course, about 1 mile south of the Van Nuys Airport. The aircraft touched down on it's main landing gear and bounced three times. The nose of the aircraft struck a 24-inch-high (61 cm) concrete foundation of a partially constructed building. The aircraft came to rest against a house trailer parked nearby and caught fire about 20 minutes after it came to rest. Three crew members were killed while three other occupants were injured.

The crew departed Alameda NAS for a training mission when the airplane crashed in unknown circumstances in a mountainous area located 11 miles south of Ukiah. Both pilots were killed.

While in cruising altitude, the pilot encountered poor weather conditions with rain, turbulences and thunderstorm activity. While flying under VFR mode, he lost control of the airplane that entered a dive. It suffered an in-flight failure then crashed inverted in water near Walnut Grove. All six occupants were killed. VFR flight was not recommended by FSS.

The crew was engaged in a local training flight out from El Toro MCAS. After takeoff, while climbing, the airplane went out of control and crashed in the garden of the Saddleback College located about 8 miles southeast of the airfield. Four crew members were killed while two others were injured.
