## 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 DEN05LA086](https://openairdocs.org/ntsb/DEN05LA086), Jun 7, 2005: Beech S35 (N9TT), Broomfield, CO, substantial damage. Probable cause: the pilot's failure to maintain adequate airspeed which resulted in a stall, and his failure to abort the takeoff. The loss of power for undetermined reasons is a contributing factor.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft 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.
