## NTSB investigations that cite this AD (2)

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 DEN03FA068](https://openairdocs.org/ntsb/DEN03FA068), Apr 17, 2003: Cessna 310D (N6861T), Provo, UT, destroyed, 3 fatal. Probable cause: failure of the student to maintain aircraft control. Contributing factors were the instructor's inattention to the fuel supply, fuel exhaustion, an inadvertent stall/spin during the turn from base…
