Captain / Total flying hours:

Circumstances:
Shortly after takeoff from Burbank Airport, while climbing to a height of 1,000 feet in limited visibility due to fog and night, the aircraft entered an uncontrolled descent, collided with power cables and crashed in a field, bursting into flames. All three occupants, two pilots and a stewardess, were killed.
Probable cause:
Several theories have been suggested as the probable cause of this accident. However, to date, no direct evidence has been uncovered which will substantiate any of them. Thus, it is the opinion of the Accident Board that the probable cause of this accident was failure of the pilot to maintain proper control of the aircraft while climbing through fog. It is believed he suffered a spatial disorientation while climbing in low visibility due to poor weather conditions.

Circumstances:
The aircraft departed Los Angeles in cloudy conditions (ceiling at 600 feet). The pilot was certain that visibility was better outside the city when few minutes later, he encountered foggy conditions. With a ceiling at 2,330 feet, he decided to get around the clouds and went into a canyon when the airplane impacted a hill side. All four occupants were seriously injured and the aircraft was destroyed by impact forces.
Probable cause:
It is the opinion of the Accident Board that the probable cause of this accident was poor judgment on the part of the pilot for attempting this flight under weather conditions which existed at the time and for continuing flight up a canyon until engulfed in fog which could have been avoided and for attempting a turn in a canyon so narrow that there was not a reasonable expectancy of being able to complete the turn.
