From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.
What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
During cruise climb at 16000 ft, the pilot and his observer (certificated pilot but not required crew) noticed abnormal right engine torque and temperature indications. After briefly discussing the issue, the pilot in command elected to shut down the right engine and return to Deer Valley Airport. The aircraft landed uneventfully.
