## The NTSB's investigation of this event (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 CEN11LA543](https://openairdocs.org/ntsb/CEN11LA543), Aug 3, 2011: Aero Commander S2R (N1735S), Washington, IA, substantial damage. Probable cause: The loss of engine power for reasons that could not be determined because postaccident examination of the airframe and engine did not reveal any anomalies that would have precluded normal operation.
