## NTSB investigations (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 pilot's operation of the aircraft above maximum gross weight, resulting in her inability to attain a sustained climb rate after becoming airborne.
