ERA16LA153

The sport pilot/mechanic reported that the accident flight was the first flight in the experimental, amateur-built airplane after he installed an overhauled engine. About 30 minutes after takeoff, the engine experienced a sudden and total loss of power and would not restart. The pilot then conducted a forced landing to a grass field, and the airplane nosed over. The pilot and another mechanic subsequently performed a condition inspection of the airplane and found that fuel had leaked from the gascolator between the glass cup and metal frame. They also found that the gascolator bale clamp was not safety-wired, which allowed the clamp to loosen and subsequently relax the seal between the glass cup and the metal frame and the fuel to leak.

On April 2, 2016, about 1530 eastern daylight time, an experimental amateur-built Ginny B, N349E, was substantially damaged during a forced landing in South Harrison Township, New Jersey. The pilot sustained minor injuries. Visual meteorological conditions prevailed, and no flight plan had been filed for the local flight from Alloway Airfield (NJ02), Alloway, New Jersey. The personal flight was conducted under the provisions of 14 Code of Federal Regulations Part 91.According to the pilot, who also held an airframe and powerplant (A&P) certificate, the flight was the first since he overhauled and installed a Continental O-200 engine. The pilot took off about 1500, and headed north from the airport. About 30 minutes later, the engine experienced a sudden and complete loss of power, and the pilot could not get it restarted. The pilot then completed a forced landing to a grassy field, where the airplane nosed over. The airplane's wing spar, vertical stabilizer, and right wing struts were substantially damaged. The pilot and another A&P rated mechanic subsequently performed a conditional inspection on the airplane, where they found that fuel had leaked from the gascolater between the glass cup and the metal frame. They also noted that the bale clamp was not safety-wired, which allowed it to loosen and relax the seal between the gascolator glass cup and its metal frame.
