Probable cause:
Improper IFR operation on part of the flying crew. The following factors were reported:
- No record of weather briefing received,
- Weather forecast unknown or not reported,
- Hit mountain at 6,060 feet approximately 1,6 NM from VOR,

Aircraft flight cycles:

Circumstances:
The crew was completing a training flight from Los Angeles to Ontario. The pilot under supervision was supposed to complete an ILS approach with one engine inoperative, to make a missed approach and a go-around procedure. On final to runway 25R, the airplane went out of control and crashed in a field. The airplane was totally destroyed and all five crew members were killed.
Probable cause:
The failure of the aircraft rudder hydraulic actuator support fitting. The failure of the fitting resulted in the inapparent loss of left rudder control which, under the conditions of the flight, precluded the pilots’ ability to maintain directional control during a simulated engine-out missed-approach. The existing weather conditions degraded external visual cues, thereby hampering rapid assessment of aircraft performance by the flight check captain.
