Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

Full Narrative
On September 12, 1993, about 1835 eastern standard time, a Cessna 172F airplane, N5678R, experienced partial loss of engine power during cruise and landed off-airport near Fishers, Indiana. The private pilot and two passengers reported no injury. The airplane was substantially damaged in the forced landing. The flight originated about 1630 EST in Galion, Ohio, without a flight plan and operated in visual meteorological conditions under 14 CFR 91. According to the pilot, after descending from an altitude of 4500 feet MSL to 2500 feet MSL, the airplane's right magneto failed. The pilot states the airplane then misfired on the left magneto. Not being able to maintain altitude due to low RPM, he performed emergency procedures and initiated a forced landing onto a field. Postaccident investigation revealed the left magneto was inoperative.
