NTSB summary
HISTORY OF FLIGHT On March 30, 2007, at 0144 Pacific daylight time, a Ryan Navion A single engine airplane, N4369K, was destroyed during an in-flight breakup while maneuvering near Los Banos, California. The owner/pilot was operating the airplane under the provisions of 14 CFR Part 91. The private pilot and one passenger sustained fatal injuries. The local personal flight departed Los Banos about 0124 with an unknown destination. Night visual meteorological conditions prevailed, and no flight plan had been filed. Family and friends of the pilot and passenger were interviewed by the local authorities. During the interviews, local authorities determined that both the pilot and passenger had each consumed between 8 to 10 beers between 1800 and 2400 on March 29, 2007. Prior to the flight, the pilot and passenger had departed from a local bar in Los Banos where patrons had overheard discussions between them about doing some "crazy" aerobatics. The National Transportation Safety Board investigator-in-charge (IIC) reviewed recorded radar data for the area of Los Banos Airport. At 0124, on March 30, 2007, radar data showed a secondary 1200 (visual flight rules - VFR) beacon code at a mode C reported altitude of 1,500 feet msl (mean sea level). The data showed the recorded radar target departed to the south, and climbed to a mode C reported altitude of 7,000 feet; it then began maneuvering in the general area of Los Banos. The radar target indicated a maximum altitude of 8,000 feet msl, with the indicated altitudes varying erratically between 7,000 and 5,000 feet. The calculated gro
Probable cause
the pilot's intentional performance of aerobatic maneuvers that exceeded the design stress limits of the airplane structure. Also causal was the pilot's impairment due to the effects of alcohol consumption. Contributory was the pilot's impairment due to the effects of prescription medication.
