What happened
During a flight through inclement weather, an airplane impacted the side of a mountain within the San Benito area. The wreckage of the aircraft remained undiscovered for 12 days following the impact. There were three fatalities among the crew members on board.
Findings
Investigations into the accident revealed that the aircraft was operating at an altitude that was too low for the terrain being traversed. Additionally, the flight path had deviated from its designated airway. The investigation concluded that the primary reason for the collision was that the aircraft was not maintaining a sufficient altitude to safely clear the mountain range. A contributing factor noted in the findings was the absence of available navigation aids in the vicinity at the time of the accident.
