The NTSB's narrative final · quoted from the NTSB record
The experimental amateur-built Hawk Aero Tandem airplane sustained substantial damage during an emergency landing following a loss of engine power during cruise. The pilot stated that he had lost engine power after restarting the engine twice. He impacted a mound with his nose landing gear. A witness saw liquid in the fuel tank when the airplane was disassembled. The airplane was powered by a Hirth 2706 fuel-injected engine. The Blue Max two cycle oil's recommended fuel and oil ratio was 100:1. An engine manual supplement noted that the recommended fuel and oil mixture was 90:1 for fuel injected engines. The pilot reported that he used a 100:1 fuel/oil ratio. A representative of the engine repair facility stated, "This engine experienced a piston seizure of the mag[neto] end piston. ... The PTO side piston is undamaged and from inspection of this cylinder it appears that possibly there was too lean of an oil mix in the fuel."
