The NTSB's narrative final · quoted from the NTSB record
A flight instructor (CFI) was providing a Biennial Flight Review (BFR) to the owner of a tailwheel equipped airplane. The airplane's last annual inspection had lapsed, and the owner's BFR was not current. The owner filled the airplane's fuel tanks from a personally owned fuel tank that contained a mixture of 25 percent aviation fuel and 75 percent automotive fuel. The owner said he drained the airplane's fuel tanks before the flight, and did not notice any contamination. An engine run-up was completed without any deficiencies, and the fuel selector was positioned to the left tank. After takeoff, about 400 feet above the ground, the engine began to lose power and run rough. The owner selected an emergency landing area in an area of small trees and brush. The airplane collided with several trees, and received damage to the fuselage and wings. Postaccident examination of the airplane revealed water in the carburetor and the left wing fuel tank. An analysis of fuel from the owner's fuel tank failed the specifications for aviation gasoline.
