On December 31, 1993, approximately 1400 mountain standard time (MST), a Swiss registered Glasair I RG experimental aircraft, HBYDJ, impacted the terrain during a forced landing near Ogden, Utah. The private pilot, who was the sole occupant, was not injured, but the aircraft sustained substantial damage. The pilot, who was on a local pleasure flight, departed Ogden-Hinckley Municipal Airport about 20 minutes earlier. The pilot had not filed a flight plan, and there was no report of an ELT activation. According to the pilot, the engine lost power, and he attempted a forced landing on rough soft terrain. During the emergency descent, he made the decision to land with the gear up in an attempt to minimize the damage to the aircraft. An FAA inspector who responded to the accident found that a stainless steel nut on the fuel line-to-engine fitting had come loose, resulting in an interruption in the fuel flow to the engine. According to the pilot/manufacturer, the nut that came loose had been used to hold the fuel line to the engine for over 85 hours of powerplant operation.
