NTSB investigations: Lycoming 0-320 series
135 cases on aircraft whose registry engine model is Lycoming 0-320 series, where the defining event was Loss of engine power (partial). Aircraft are matched to the registry by N-number and event date, checked against the reported serial number, make and model, so older matches can be wrong.
