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.

Examination of the engine provided no evidence of mechanical failure or malfunction; however, it did provide evidence of an overly lean mixture in the form of white carbon like material on the spark plugs. Verification of fuel remaining at the time of the accident was not possible due to impact damage which compromised the fuel system. (-23)at final approach to landing runway 27 at tex lost power at approx 300' above landing height, unable to regain power landed off airport.
