## NTSB investigations (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 CEN11CA685](https://openairdocs.org/ntsb/CEN11CA685), Sep 6, 2011: Cessna A185F (N550DP), Hays, KS, substantial damage. Probable cause: The pilot's improper recovery from a bounced landing, which resulted in a loss of control.

Probable cause: THE INADEQUATE COMPENSATION FOR THE WIND CONDITIONS BY THE PILOT WHICH RESULTED IN A LOSS OF DIRECTIONAL CONTROL ON LANDING AND SUBSEQUENT COLLISION WITH A DITCH.
