## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

Probable cause: Improper overhaul of the right magneto, which eliminated system redundancy, and resulted in a loss of engine power when the left magneto failed during aerobatic flight maneuvers.
