From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) Shortly after reaching cruise altitude, pilot experienced elevator control problems. Using elevator trim and engine power he maintained a controlled descent but was forced to land prematurely 1 mile short of destination airport. Minor injuries to pilot and occupant. Aircraft obtained substantial damage. Post accident examiniation revealed fwd rod end of acft elevaor rod became disengaged. (-4) on April 15, 2000, at 1119 hours pacific daylight time, a homebuilt smith RV-4, N63SM, made an off-airport forced landing after experiencing elevator problems in cruise flight at Willows, California. The airplane, owned and operated by the pilot, sustained substantial damage. The pilot and passenger suffered minor injuries. The personal flight, conducted under the provisions of 14 CFR part 91, originated from lincoln, California, about 1045, and was en route to Willows. Visual meteorological conditions prevailed and no flight plan was filed. The pilot reported that the passenger had been flying the airplane from the backseat, and about 8 miles south of Willows, the passengerinformed him that he had no fore or aft control authority. The pilot took the controls and comfirmed that there was no elevator response from the stick but that he did have control continuity to the ailerons. The pilot stated that he planned to land using the manipulation of a/c trim and throttle as a means of controlling the a/c's pitch attitude. In an effort to avoid making any major heading changes, the pilot attempted to land on closed runway 30 because of his present near alignment with the runway. Due to the lack of control authority to the elevator, the pilot attempted to gain altitude by trimming the airplane in the full aft position. Due to insufficient altitude to make the airport, the pilot reduced the throttle and mixture controls and landed in a rice field about 1 mile south of the airport, coming to rest in an upright position. A FAA inspector from the sacramento flight standards district office examined the airplane following recovery. He reported that the rear jam nut on the elevator push rod had worked loose, allowing the oush rod to rotate off the forward connection. He stated that the jam nut and controlrod were improperly installed.
