  - flare - improper, pilot in command (cause)
  - recovery from bounced landing - improper, pilot in command (cause)

THE PILOT SAID THE ACCIDENT COULD HAVE BEEN PREVENTED WITH LESS CONTROL INPUT, TIMELY USE OF DIVE BRAKED AND LESS AIRSPEED ON FINAL APCH.

## 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 19861130063719A](https://openairdocs.org/incident/19861130063719A), Nov 30, 1986: Scwzer SGS233A, Wurtsboro, NY, Substantial damage. On landing, the aircraft porpoised 4 times before severely damaging the glider. Gusting winds a factor.

## Other investigations on N1222S (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.
