## 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: A partial loss of engine power due to a stuck engine exhaust valve during takeoff initial climb. A contributing factor was the airplane's excessive gross weight.
