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.

Narrative: malfunction or defect report FAA form 8010-4 submitted. On August 7, 1996 at approximately 1630 cdst a Cessna, C172N, N4949G, made an emergency landing in a hay field on county hwy mm, Cadott, chippewa county, Wisconsin. The aircraft did not sustain any damage. The ATP rated pilot and passenger did not report any injuries.

Visual meteorological conditions prevailed. No flight plan was filed. The pilot stated, he experienced a rough running engine at lever cruise flight followed by degraded power output and was unable to maintain altitude. On site evaluation of the engine revealed the magnetos points were not opening due to excessive wear on the point's cam follower. This wear was accelerated by a heat build-up, on the magneto shaft, generated by a failed rear bearing. A malfunction or defect report, FAA form 8010-4, has been submitted pertinent to this part failure.
