## 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.

- [NTSB ERA20CA106](https://openairdocs.org/ntsb/ERA20CA106), Feb 18, 2020: Aerospatiale AS350 (N188FS), Tampa, FL, substantial damage. Probable cause: The flight instructor's inadvertent throttle reduction below idle, which resulted in a total loss of engine power and subsequent impact with terrain following a power-off autorotation.
