The NTSB's narrative final · quoted from the NTSB record
A non-certificated pilot was flying a weight-shift control airplane, and he reported that he had developed “mechanical problems” and was going to fly under a set of electrical wires to land in a vacant lot; the airplane impacted the wires and terrain. The pilot added that, prior to the accident flight, he had landed due to a fuel problem, repaired the problem, and departed. The pilot died about two weeks after the accident, in a manner unrelated to the accident. Circumstances surrounding the pilot’s death precluded a detailed examination of the airplane and engine.
