## NTSB investigations (3)

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.

- [NTSB LAX08LA098](https://openairdocs.org/ntsb/LAX08LA098), Apr 11, 2008: North American T-28C (N9022N), Kingman, AZ, substantial damage. Probable cause: A total loss of engine power during cruise flight due to an undetermined catastrophic internal engine failure.

Probable cause: the failure of the pilot to refuel the airplane resulting in fuel exhaustion. A contributing factor was the lack of suitable terrain for the forced landing.
