## Other investigations on N5221P (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: THE LOSS OF ENGINE POWER DUE TO A BENT PUSH ROD AND THE RESULTANT LOSS OF OIL. FACTORS WERE THE COCKPIT SMOKE AND THE LACK OF SUITABLE TERRAIN FOR THE FORCED LANDING.
