Fatal Training Flight Accident at Santa Maria AFB (2457)

Incident Overview and Context A crew was conducting a local training flight at Santa Maria Air Force Base when the accident occurred. The flight was part of a new circuit, and the crew was operating under conditions that would later prove critical to the outcome of the event. The source does not specify the aircraft type, registration, date, or operator, so those details are not included in this account. ## Weather Conditions and Flight Progression During the new circuit, weather conditions deteriorated. Visibility became limited due to fog, which affected the crew's ability to maintain situational awareness. The source does not provide additional details about the specific weather parameters, such as visibility distance or wind conditions, beyond the presence of fog and limited visibility. ## Final Approach and Impact On final approach, the crew failed to realize that the aircraft's altitude was too low. The aircraft subsequently struck the ground and disintegrated. The impact occurred a few kilometers from the airport. The source does not specify the exact distance, the terrain type, or the direction of the approach. ## Casualties and Outcome All seven crew members were killed in the accident. The source does not provide further information about the identities, roles, or nationalities of the crew members. ## Probable Cause The source does not state a probable cause. It describes the sequence of events, including deteriorating weather, limited visibility due to fog, and the crew's failure to recognize low altitude on final approach, but it does not assign a formal cause or contributing factors.
