Incident Overview
The airplane impacted upsloping mountainous terrain while in level controlled cruise flight during a night cross-country journey. According to radar data, the pilot was cruising at approximately 6,500 feet as indicated by the mode C altitude reporting transponder. The flight was conducted under radar flight following service provided by a controller at the Los Angeles Air Route Traffic Control Center.
Pre-Flight and Weather Conditions
Prior to departure, the pilot informed the air traffic controller that he had received the airport's weather. The reported sky condition was broken, with layers at about 5,500 and 7,000 feet mean sea level. During the initial climb, the pilot requested information from the controller regarding cloud elevation, acknowledging that he "seems to be in a little bit of clouds...sort of in and out." He subsequently climbed into clearer conditions.
Flight Path and Communication
The airplane tracked near the centerline of Victor Airway 183, which has a published course of 195 degrees. The pilot was familiar with the roundtrip route between his home-base airport at Santa Barbara and Bakersfield, having flown it previously. During the final minutes of the radar-recorded flight, the pilot maintained a general cruising altitude of about 6,500 feet. The controller was aware that the minimum enroute altitude for aircraft on instrument clearances along the airway was 9,000 feet. Both the controller and the pilot had sectional aeronautical charts available, which depicted a 6,840-foot mean sea level mountain peak along the flight route.
Collision and Impact
The pilot's course did not deviate as he approached and struck the mountain during the dark nighttime flight. The bearing from the initial point of impact to the Santa Barbara Municipal Airport was 197 degrees. Additionally, the bearing and distance between the initial point of impact and the main wreckage were 198 degrees and 0.25 miles, respectively.
Controller Actions
The controller did not issue a terrain-related safety alert, as required by a Federal Aviation Administration order.
