## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19880119000979A](https://openairdocs.org/incident/19880119000979A), Jan 19, 1988: Dhav DHC6TWNOTTER, Charlotte, NC, Substantial damage. Struck trees on a night ILS approach short of the runway and below glide slope altitude. Ceiling was near zero.

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.
