Flight Preparation and Conditions
The two private pilots, who were not instrument rated, did not obtain a weather briefing or file a flight plan for their night cross-country flight. The flight occurred during dark night conditions.
Witness Observation
A witness observed the helicopter descending from the clouds while following a highway. The helicopter appeared to be at an altitude just above a 285-foot tall radio tower.
Sequence of Events
Approximately 5 miles south of the radio tower, the helicopter struck an electrical pole, then impacted terrain. It came to rest adjacent to an oil pump jack.
Weather Study
A weather study conducted after the event revealed that the accident site was located in an area characterized by low ceilings and restricted visibility.
Examination Findings
During examination of the helicopter, no anomalies were found with the engine or airframe that would have precluded normal flight operations.
