## 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 LAX96LA343](https://openairdocs.org/ntsb/LAX96LA343), Sep 20, 1996: Aero Commander 690 (N840DC), Truckee, CA, substantial damage. Probable cause: The inadequate visual outlook by both pilots while in the vicinity of the airport. A factor was that each aircraft was on a different frequency at the time.

## FAA accident and incident reports (1)

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.

- [Accident 19960920034351A](https://openairdocs.org/incident/19960920034351A), Sep 20, 1996: Gulstm 690C (N840DC), Truckee, CA, Substantial damage. Tuning radio during climb through FL190, failed to see and avoid a glider that was thermaling. Wing tips hit.
