## 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 WPR11LA265](https://openairdocs.org/ntsb/WPR11LA265), Jun 18, 2011: Aerovodochody L-29 Delfin (N37KF), Reno, NV, substantial damage. Probable cause: The failure of a modified engine mount to keep the engine properly aligned, which resulted in partial failure of the rudder support structure due to the deflection of the jet engine exhaust.
