Circumstances:
The airplane departed San Pedro-Catalina NAS (Long Beach) on a flight to Alameda NAS in Oakland, carrying 20 passengers and a crew of three. The descent was initiated at night when the crew encountered limited visibility due to poor weather conditions. Following an unsuccessful landing, the crew followed a missed approach procedure when he got apparently lost. The airplane impacted the slope of a hill and crashed at an altitude of 630 feet about two miles west of San Carlos. All three crew members were killed as well as four passengers. At the time of the accident, weather conditions were poor with heavy rain falls, clouds down to 500 feet and visibility less than three miles.

Circumstances:
Shortly after takeoff from runway 27, while in initial climb by night and in marginal weather conditions, the pilot made a turn to the right when the right wing tip hit the water surface. The aircraft crashed into the Bay of San Francisco and none of the 24 occupants survived. The cloud ceiling was down to 500 feet at the time of the accident with a good visibility under the cloud layer.
Probable cause:
The crew was unaware of his real position after takeoff due to the malfunction of a gyro. Because the aircraft was flying over the Bay of San Francisco and due to lack of visibility and the absence of ground visual references, the crew lost his bearings during initial climb.

Circumstances:
Following an uneventful flight from El Paso, the crew started the approach to Burbank-Hollywood-Lockheed Air Terminal at night. Due to low visibility caused by poor weather conditions, the pilot was unable to localize the airport and decided to proceed to the alternate airfield, Palmdale. Few minutes later, as it was flying at a too low altitude, the aircraft hit tree tops and crashed on the slope of a wooded hill located in the Verdigo mountains, some 4 miles northeast of the Burbank Airport. All 24 occupants were killed.
Probable cause:
The possibility of an accident became a potentiality when the company ground personnel failed to obtain and transmit important weather to the pilot. Failure to obtain and transmit this information to the pilot constitutes negligence on the part of the company. This, however, did not relieve the pilot of his responsibility to conduct a safe flight although it did place him in a disadvantageous position. Had no properly execution the "missed-approach" procedure it is unlikely that the accident would have occurred. The Board, therefore, determines that the probable cause of this accident was "the pilot's attempt to use the standard 'missed-approach' procedure after having followed another course up to a point there it was impossible to apply this procedure safely."

Circumstances:
The flight was cleared to Burbank Airport for a standard instrument approach. During the approach the plane descended under instrument conditions to such a low altitude as to clip the tree tops and strike a power line pole and then crash at a point approximately 6 1/2 miles short of the Burbank Airport. In a normal approach the plane would have flown over this point at an altitude of about 1650 feet above the ground. The specific reasons for the plane's descent below the minimums for instrument approach were not determinable, nor was it possible to tell whether the deviation was a voluntary one. Investigation did reveal, however, that a number of divisions were made from the company's standard Civil Aeronautics Administration approved procedures during this flight. Both pilots and six passengers were killed.
Crew:
John Pollard Snowden, pilot, †
Thomas Leo Bamberger, copilot, †
Donna Elizabeth Marr, hostess.
Probable cause:
On the basis of the evidence available the Board finds that the probable cause of this accident was the pilot's deviation from the standard instrument approach procedure then he descended below the established safe minimum altitude. A contributing factor was the company's failure to enforce adherence to company procedures.

Probable cause:
According to investigations, the sky was broken at the time of the accident, with scattered showers. Due to an insufficient visibility, it was concluded that weather conditions were unsuitable for such transpacific flight. The crew was unable to detect the mountain because it was shrouded by clouds and the visibility was low due to night.
